yeah that should make very interesting reading Erich...........
Erich:
Have you read Niklas Zetterling´s account on the matter?
I found his work very illustrative as to the real accuracy of P-47s, Typhoons and Tempests attacking German armored columns.
Not only that the RAF hit a small number of panzers and vehicles, losses of fighter-bombers were heavy when greeted by Flak batteries attached to armored colums.

yes Udet............
major bummer for the Allies !! so much for rocket attacks and all the scores put in by the US 9th AF Jugs for ground kills.
If the work on heavy bomber targets could not be immediately applied it nevertheless provided a foundation for other studies of the battlefield. Schonland had long been anxious to know something concrete about the effectiveness of fighter and fighter bomber close support. This was an issue which was causing much difficulty between the army and air force and 21 Army Group badly wanted to know what was going on.
Major Pike had already studied one Typhoon attack on a German column near La Baleine in the American sector. Together with a young RAF Pilot Officer, Pike had surveyed the aftermath of the air attack and had noted that only one tank had actually been hit by a Typhoon rocket projectile. This report was not well received by Second Tactical Air Force (2 TAF) and the Pilot Officer was sent back to do the investigation again.99
On August 8th word came that the team was to proceed to the town of Mortain in the American zone. Here, the RAF proclaimed, the tactical air force had been "a decisive battle winning factor" in stopping the German counterattack to cut off the American troops south of Avranches. According to Air Marshal Coningham, the commander of Second Tactical Air Force, rocket firing typhoons claimed to have destroyed 89 tanks, probably destroyed another 56 tracked vehicles, set on fire 104 motor vehicles and saw 47 motor vehicles smoking. These claims do not include 56 enemy tanks damaged and 81 motor vehicles damaged. 100 It had been, the air force insisted, "The Day of the Typhoon."
The army OR section was not the only group interested in the Mortain battlefield. When Second Tactical Air Force was formed in 1943 it acquired operational research staff from Fighter and Army Cooperation Commands. Fighter Command had a good deal of experience with OR work and had amassed considerable information about attacks on ground targets. For example, in early 1943 a full scale model of a German artillery division with 48 mock guns and 558 dummy soldiers was created. "Every effort was made to aid the fighters and fighter bombers in their attack task, but neither Mustangs strafing, nor Typhoons firing their new rockets with 60 lb. warheads were able to inflict more than negligible damage on the position.""" A second experiment with a mock up troop of medium artillery produced equally dismal results.
A carefully controlled study of the ability of pilots to find specific positions on the ground produced even more startling information. Tactical Memorandum No.30, dated March 1943, reported that:
fighters, given a six figure map reference were unable to spot well camouflaged guns even when the guns were actually firing ... attacks on gun positions give negligible results for a high wastage and should only be ordered in an emergency. 102
After 2 TAF was established, OR studies continued to show that there were very real problems in attacking the kind of targets which were of interest to the army. Operations against a variety of targets were carefully examined in the pre D Day period. Typhoon rockets were found to hit a viaduct 500 yards long and 8 yards wide, one in 15 times. Bombs dropped from fighter bombers scored hits one in 82 times. Rocket Projectile (RP) attacks on gun positions produced results varying from 110 rockets fired at a casement in Courseulles sur Mer with zero hits to two hits out of 127 at Fontenay. Second TA F found all this disappointing, particularly since none of the targets had been "well defended."103
The Allied Expeditionary Air Force (AEAF) established a school for training fighter pilots in close support during 1944. Results were not encouraging, for while strafing was "outstandingly successful" for damaging or destroying soft skin vehicles, bombs and rockets could not be delivered accurately by average pilots. Near misses, it was found, did little damage. Even worse, accurate target location and identification of friendly troops proved to be an art which was readily mastered by very few pilotS.104
The AEAF operational research section concluded that the probability of pilot error in identifying friendly troops and the inaccuracy of rocket and bombing attacks meant that close support of army operations should be ordered only in an ernergenCy.105 This information confirmed 2 TAF's preference for missions involving armed reconnaissance, deep interdiction and the search for targets of opportunity well beyond the battle lines. Nothing in the first two months of the campaign had altered this view, but if the Typhoons had really stopped the German armour at Mortain the whole question of close support might need to be re examined and 2 TAF ordered its OR section to the scene of the battle.
The two rival OR groups began work at Mortain as soon as the German retreat cleared the area. For eight days, August 12th to August 20th, a not entirely friendly competition to locate and examine German tanks, self propelled guns and other vehicles was underway along the roads and lanes of the hilly countryside. Descriptive accounts of the battle, as well as air force claims, had prepared the investigators for scenes of devastation. A Panzer division, it was said, had been caught in a traffic jam caused by the crash of an Allied aircraft onto the lead tank in the column. Scores of panzers had been destroyed near St. Barth61emy, and this was just one among many stories that everyone had heard.
What the researchers saw was very different. Despite the most systematic search, very few wrecked tanks could be located. The army team borrowed an Auster aircraft to conduct a survey, but not a single additional vehicle was seen. In the end only 33 Panthers, 10 Mark IVs and 3 self propelled guns were uncovered. If armoured troop carriers, armoured cars and tank recovery vehicles were added, the total for all armour left behind in the area was 78. Nor was it possible to find many of the motor vehicles which the air force had claimed to have destroyed. Only 30 German trucks were available to investigate. While this discrepancy was difficult enough to account for, the results of the individual examination of vehicles was even more problematic. Nineteen of the 43 tanks had definitely been destroyed by US Army units. Only seven tanks showed signs of being struck by rocket projectiles. Two had been disabled by US Army Air Force bombing, seven had been abandoned without a mark on them, and four had been destroyed by their crews. The fate of just three tanks was judged to be from unknown causes .106
The Army OR group was quite prepared to accept the argument that air power might be credited for some of the abandoned and crew destroyed tanks. Their report, however, noted that these tanks could not be taken into consideration when comparing pilots' claims of having destroyed or damaged vehicles. Major Pike's dispassionate analysis of the evidence angered the RAF and provoked outrage at 2 TAF headquarters. An official air force review of the events was quickly developed. It is worth quoting at length:
Ground Investigation:
An attempt was made to examine the area on the ground within five days of the air attacks. However, at that time, fighting was still in progress and it was not until 20th August 1944 that the examination was completed. Nevertheless 39 tanks and 58 other vehicles, or the remains thereof, were examined. An analysis of the extent to which these were damaged is given below:
Destroyed . Damaged . Abandoned, Slightly damaged or untouched
Tanks . . . .24 . . 10 . . 5
Other Veh. . . 32 . . 23 . . 3
The German recovery service is remarkably efficient, and on this occasion there was very definite evidence that it had been as efficient as usual. Eye witnesses confirmed this fact. It can therefore be safely assumed that the vehicles found were only a small proportion of those actually destroyed and damaged, and probably an even smaller proportion of those which, although only slightly damaged, had been abandoned by their crews. To attribute destruction or damage to a particular arm or weapon is particularly difficult; however, taking into account the number of vehicles found, surrounded by rocket craters, and others with almost certain rocket or 20min strikes, it appears that the claims were reasonable. It is inevitable that when a large number of aircraft are operating in a comparatively small area, that certain claims will be duplicated. There is no reason to believe, however, that on this occasion the duplication resulted in anything but a small over statement of the damage inflicted.
Officers and other ranks who witnessed the attacks were effusive in their praise of their effectiveness. They freely admitted that had the counter attack continued with the same determination as before the Typhoons had appeared, they would have been unable to repel it."107
This was a serious distortion of the evidence which the Army OR group could not let pass unchallenged. Major Pike, in his report, directly contradicted the RAF view:
The efficiency of the German recovery system has been put forward as an explanation of the large discrepancy between the number of vehicles claimed to be destroyed and the actual number found. Tanks and lorries that are destroyed as a result of air attack are almost always burnt out and would not be worth salvaging unless time and labour were both very plentiful. Many prisoners have been questioned on the subject of the recovery of tanks and it has been established that burnt out tanks are never salvaged. In addition it has been ascertained that, contrary to certain statements made about the Mortain battle, very little recovery was done in this part of Normandy at the time; in fact the repair and recovery teams were already pulling out of Normandy when the battle of Mortain was at its height."108
The Army OR group agreed that the Allied Air Forces had a "considerable effect" on the German attack at Mortain. But nothing remotely resembling the air force claims could be justified. 1ndeed, in many areas of the battlefield, no signs of the characteristic rocket crater could be found. The RAF ought to have accepted this view, for it knew from its own recent research that there were serious aiming problems with rocket (and bomb equipped) Typhoons.
The most recent RAF study on the "accuracy of attacks" had been completed in June 1944. It showed that under the most favourable conditions average pilots were lucky to concentrate their rockets in a circle 150 yards in diameter. The report stated:
In order to hit a small target with R.P. the pilot must be at the right height and dive angle, have the correct speed, have his sight on the target and the right angular depression on his sight, make the correct wind allowances and be free from skid or 'g' ...
All of these factors are important but it is very difficult for a pilot to have them all right at the same time."109
The report raised the question of what really happened in combat when the pilot was also being harassed by anti aircraft fire. It concluded that previous views of the accuracy of RP attacks and of divebombing (which was even more subject to aiming error) were wrong. Such ideas must have been based on "the performance of a few very keen and experienced pilots who can hit small objects, such as tanks, with R.P.'s." Such men might be grouped into a "corps d'elite" capable of attacking special targets but only continual training and practice could improve the accuracy of most of the TAF pilots.""
The rival OR teams next raced north to examine the battlefield around Falaise and the roads leading to the Seine crossings. Here there were thousands of wrecked vehicles to investigate and a new round of argument over the role of air power to be waged. The army investigators would once again report that their three week investigation established beyond dispute that the devastation of the German forces in the area known as the "Shambles" was not due to direct air attack. Only 11 of 171 armoured fighting vehicles examined had been hit by bombs or rockets. No doubt the air force had assisted in destroying German morale strafing had accounted for a third of all soft skinned vehicle losses but, in the words of the OR report, the destruction of the German army had been achieved by 1and action.""'
The investigation of the Mortain battle continued to produce sparks. After one particularly nasty exchange, Brigadier Schonland suggested that "unless there were fairies in Normandy who could remove a large formation of tanks from the Mortain area," 112 it was time to accept the evidence and act on the basis of fact, not fiction. But in the summer of 1944, 2 TAF was in no mood to discuss the issues raised by Army OR. In an official "Addenda" to the Army's Report the Air Force insisted that:
It would be wrong to regard the data provided in this report as yielding information on which to make recommendations for changes in weapons, tactics or operational doctrine, although the factual side of the report can itself be accepted. 113
If it was not permissible to use accepted data as the basis for recommendations about "changes in weapons, tactics or operational doctrine" then there was little point to further investigation of tactical air power. However, 21 Army Group was not about to give up its attempts to influence tactical air doctrine. A formal agreement was negotiated between Schonland and 2 TAF which provided for joint investigations of air operations against ground targets.
Air Force and Army OR researchers prepared four Joint Reports in the fall and winter of 1944-1945. 114 Again there was no disagreement about the evidence. For example, in Joint Report No.3 titled "Rocket Firing Typhoons in Close Support of Military Operations," it was found that 350 rockets, involving 44 sorties, would have to be fired at a small gun position to obtain a fifty percent chance of a hit.115 Typhoons were clearly weapons which were best used to reduce enemy morale and raise the morale of Allied infantry. Both doctrine and the manner of planning operations needed to be revised to take account of this new information as had been done in the US Ninth Air Force.116 The RAF, however, would not budge. The German offensive in the Ardennes provided the section with another opportunity to study the hard evidence on the role of tactical air power and once again their findings challenged the accepted interpretation. Almost the entire section was involved in the ground search while D.N. Royce worked his way down the line of communications interviewing prisoners of war. 117

this is report number 4 written by the Number 2 of the ORS in NW Europe July and August of 44..........Mortain
Report No.4
Air Attacks on Enemy Tanks and Motor Transport in the Mortain Area, August 1944
Tactical Situation
1. At the beginning of August 1944, the Allied armies had begun their break out from the Normandy beach head; the British and Canadians were pushing southward from CAUMONT and CAEN and the Americans, having driven down the west coast of Normandy, were rapidly moving eastward and northwards thereby threatening to surround the German armies in Normandy.
2. The following diary of events in the MORTAIN area illustrates the circumstances in which the air attacks took place:
6 Aug. During the day the enemy counter attacked strongly against 30 Inf. Div in the MORTAIN area and they re occupied the town.
7 Aug. In the early morning the enemy launched a strong armoured attack in the MORTAIN area. Although small numbers of tanks penetrated U.S. positions at a few points, the situation was soon under control. During the day large enemy concentrations of tanks and MT were attacked from the air with excellent results.
8 Aug. Little change reported. Enemy still exerted pressure in the MORTAIN area.
9 Aug. The enemy continued his efforts to break through to Avranches with the greater part of his armoured formations. Although the enemy held MORTAIN, 4, 9 and 30 Inf. Divs. with 2 and 3 Armd. Divs. resisted strongly on the high ground to the north, west and south of the town. 35 Inf. Div. made some progress with an attack SW of MORTAIN.
10 Aug. SE of MORTAIN 2 Armd. Div. made progress, reaching a point 6 miles east of the town. Heavy concentrations of enemy armour (5 divisions) remained in the MORTAIN DOMFRONT area but no large scale counter attacks developed. 4, 9 and 30 Inf. Divs. continued to meet heavy opposition.
11 Aug. The enemy withdrew from the MORTAIN salient and the town was re occupied by troops of VII Corps. North and south of the town all divisions advanced against little or no opposition.
Air Effort
3. Bad weather prevented flying in the morning of 7 August but arrangements were made for the Second Tactical Air Force to come to the assistance of the IX US Air Force as soon as conditions permitted. The weather cleared quite suddenly about mid day, between which time and dusk 294 sorties were flown by typhoons of 2 TAF in support of the American ground forces in the MORTAIN area. Although, owing to their many other commitments in France, the IX USAAF only flew some 200 sorties to MORTAIN that afternoon, they continued their attacks over the next three days and flew 441 sorties in all.
4. Conditions on the afternoon of 7 August were ideal from the pilot's point of view as no opposition was encountered from enemy aircraft nor, till late in the day, was there any appreciable flak reaction. Under cover of mist and low cloud the Germans seemed to have neglected all normal precautions and, when the weather cleared, they were sighted in large numbers head to tail in narrow roads and lanes. The pilots reported that they were able to go in very close to attack, rockets being fired at 1000 yards range and cannon and machine guns from even closer. Claims made by the pilots during the MORTAIN Battle (7th 10th August) are shown in Table 1 below:
Table 1 - Pilots' Claims
. . . . Destroyed . Probably Destroyed . Damaged . Total
Armour
2 TAF . . . 84 . . 35 . . 21 . . 140
IX USAAF. . 69 . . .8 . . 35 . . 112

Totals. . .148 . . 20 . . 60 . . 228
Grand Total
(Armour MT) . 301 . 63 . 116 . 480
Ground Investigation
5. Between 12 August and 20 August members of the Operational Research Sections from 21 Army Group and Second Tactical Air Force conducted separate ground investigations of the battle area around MORTAIN (see map at Appendix A). The results of the two investigations were compared and collated to produce the figures shown in Table II. (See opposite page)
6. It was not possible to discriminate between the victims of IX USAAF and of' 2 TAF because, although the 500 lb bomb was the favourite weapon of the former and the rocket that of the latter, American pilots fired some 600 rockets in the course of these attacks and British pilots dropped some bombs. The respective merits of the 50 calibre MG and the 20 mm cannon were not considered and all vehicles that had been destroyed by small projectiles fired from the air have been classed as "Cannon or MG."
7. Tanks and other vehicles classed as "abandoned" have not been included in the Air Total in Table 11 because, although they were probably abandoned as a result of air attack, they can hardly be considered to have been among those which the pilots claimed to have destroyed as such claims are generally supported by mentions of fire or explosion.
8. Similarly those enemy vehicles listed as "destroyed by crew" may be regarded as indirect victims of air attack but cannot justifiably be taken into consideration when comparing pilots' claims with what was found on the battlefield.
9. It is most unlikely that all of the unknown causes were due to air attack, particularly as many of them were found at considerable distances from the nearest signs of such attack and as ground forces were also fighting fierce battles in this area. However, if all the "Unknown causes" are added to the air totals, the resultant figures (armour, 21 + 15 = 36 and MT, 12 + 26 = 38) are still only about a quarter of the numbers claimed as destroyed by the air forces.
10. The area was not very extensive and as two teams were searching it over a period of several days it is not considered that any appreciable number vehicles was missed. This is confirmed by the fact that one of the investigators flew low over the area in an Auster, plotting the positions of vehicles seen from the air; no fresh vehicles were discovered by this means.
11. The efficiency of the German recovery system has been put forward as an explanation of the large discrepancy between the number of vehicles claimed to be destroyed and the actual numbers found. Tanks and lorries that are destroyed as a result of air attack are almost always burnt out and would not be worth salvaging unless time and labour were both plentiful. Many prisoners have been questioned on the subject of the recovery of tanks and it has been established that burnt out tanks are never salvaged. In addition it has been ascertained that, contrary to certain statements made about the MORTAIN battle, very little recovery was done in this part of Normandy at the time, in fact the repair and recovery teams were already pulling out of Normandy when the Battle of Mortain was at its height. In any case before considering the recovery of the "destroyed" tanks and MT, the "probably destroyed" (43 tanks and 20 MT) and the "damaged" (56 tanks and 60 MT) must have presented the recovery organisation with a large task without counting any that may have been damaged by the ground forces.
12. At Appendix B is a list of the vehicles found by members of No.2 Operational Research Section together with the causes of destruction where it was possible to assess them. No similar record is available for the vehicles which were examined only by members of ORS/2 TAF.
Conclusions
(a) The attacks by the Allied Air Forces had a considerable effect on the enemy's unsuccessful counter attack at MORTAIN.
(b) The number of vehicles claimed by the pilots as "destroyed" was about four times the actual number discovered.
(c) A number of vehicles, though not claimed by the pilots, were lost to the enemy by "indirect" air action (i.e. abandoned or destroyed by the crew).

Report No.4
Air Attacks on Enemy Tanks and Motor Transport in the Mortain Area, August 1944
Tactical Situation
1. At the beginning of August 1944, the Allied armies had begun their break out from the Normandy beach head; the British and Canadians were pushing southward from CAUMONT and CAEN and the Americans, having driven down the west coast of Normandy, were rapidly moving eastward and northwards thereby threatening to surround the German armies in Normandy.
2. The following diary of events in the MORTAIN area illustrates the circumstances in which the air attacks took place:
6 Aug. During the day the enemy counter attacked strongly against 30 Inf. Div in the MORTAIN area and they re occupied the town.
7 Aug. In the early morning the enemy launched a strong armoured attack in the MORTAIN area. Although small numbers of tanks penetrated U.S. positions at a few points, the situation was soon under control. During the day large enemy concentrations of tanks and MT were attacked from the air with excellent results.
8 Aug. Little change reported. Enemy still exerted pressure in the MORTAIN area.
9 Aug. The enemy continued his efforts to break through to Avranches with the greater part of his armoured formations. Although the enemy held MORTAIN, 4, 9 and 30 Inf. Divs. with 2 and 3 Armd. Divs. resisted strongly on the high ground to the north, west and south of the town. 35 Inf. Div. made some progress with an attack SW of MORTAIN.
10 Aug. SE of MORTAIN 2 Armd. Div. made progress, reaching a point 6 miles east of the town. Heavy concentrations of enemy armour (5 divisions) remained in the MORTAIN DOMFRONT area but no large scale counter attacks developed. 4, 9 and 30 Inf. Divs. continued to meet heavy opposition.
11 Aug. The enemy withdrew from the MORTAIN salient and the town was re occupied by troops of VII Corps. North and south of the town all divisions advanced against little or no opposition.
Air Effort
3. Bad weather prevented flying in the morning of 7 August but arrangements were made for the Second Tactical Air Force to come to the assistance of the IX US Air Force as soon as conditions permitted. The weather cleared quite suddenly about mid day, between which time and dusk 294 sorties were flown by typhoons of 2 TAF in support of the American ground forces in the MORTAIN area. Although, owing to their many other commitments in France, the IX USAAF only flew some 200 sorties to MORTAIN that afternoon, they continued their attacks over the next three days and flew 441 sorties in all.
4. Conditions on the afternoon of 7 August were ideal from the pilot's point of view as no opposition was encountered from enemy aircraft nor, till late in the day, was there any appreciable flak reaction. Under cover of mist and low cloud the Germans seemed to have neglected all normal precautions and, when the weather cleared, they were sighted in large numbers head to tail in narrow roads and lanes. The pilots reported that they were able to go in very close to attack, rockets being fired at 1000 yards range and cannon and machine guns from even closer. Claims made by the pilots during the MORTAIN Battle (7th 10th August) are shown in Table 1 below:
Table 1 - Pilots' Claims

Ground Investigation
5. Between 12 August and 20 August members of the Operational Research Sections from 21 Army Group and Second Tactical Air Force conducted separate ground investigations of the battle area around MORTAIN (see map at Appendix A). The results of the two investigations were compared and collated to produce the figures shown in Table II. (See opposite page)
6. It was not possible to discriminate between the victims of IX USAAF and of' 2 TAF because, although the 500 lb bomb was the favourite weapon of the former and the rocket that of the latter, American pilots fired some 600 rockets in the course of these attacks and British pilots dropped some bombs. The respective merits of the 50 calibre MG and the 20 mm cannon were not considered and all vehicles that had been destroyed by small projectiles fired from the air have been classed as "Cannon or MG."
7. Tanks and other vehicles classed as "abandoned" have not been included in the Air Total in Table 11 because, although they were probably abandoned as a result of air attack, they can hardly be considered to have been among those which the pilots claimed to have destroyed as such claims are generally supported by mentions of fire or explosion.
8. Similarly those enemy vehicles listed as "destroyed by crew" may be regarded as indirect victims of air attack but cannot justifiably be taken into consideration when comparing pilots' claims with what was found on the battlefield.
9. It is most unlikely that all of the unknown causes were due to air attack, particularly as many of them were found at considerable distances from the nearest signs of such attack and as ground forces were also fighting fierce battles in this area. However, if all the "Unknown causes" are added to the air totals, the resultant figures (armour, 21 + 15 = 36 and MT, 12 + 26 = 38) are still only about a quarter of the numbers claimed as destroyed by the air forces.
10. The area was not very extensive and as two teams were searching it over a period of several days it is not considered that any appreciable number vehicles was missed. This is confirmed by the fact that one of the investigators flew low over the area in an Auster, plotting the positions of vehicles seen from the air; no fresh vehicles were discovered by this means.
11. The efficiency of the German recovery system has been put forward as an explanation of the large discrepancy between the number of vehicles claimed to be destroyed and the actual numbers found. Tanks and lorries that are destroyed as a result of air attack are almost always burnt out and would not be worth salvaging unless time and labour were both plentiful. Many prisoners have been questioned on the subject of the recovery of tanks and it has been established that burnt out tanks are never salvaged. In addition it has been ascertained that, contrary to certain statements made about the MORTAIN battle, very little recovery was done in this part of Normandy at the time, in fact the repair and recovery teams were already pulling out of Normandy when the Battle of Mortain was at its height. In any case before considering the recovery of the "destroyed" tanks and MT, the "probably destroyed" (43 tanks and 20 MT) and the "damaged" (56 tanks and 60 MT) must have presented the recovery organisation with a large task without counting any that may have been damaged by the ground forces.
12. At Appendix B is a list of the vehicles found by members of No.2 Operational Research Section together with the causes of destruction where it was possible to assess them. No similar record is available for the vehicles which were examined only by members of ORS/2 TAF.
Conclusions
(a) The attacks by the Allied Air Forces had a considerable effect on the enemy's unsuccessful counter attack at MORTAIN.
(b) The number of vehicles claimed by the pilots as "destroyed" was about four times the actual number discovered.
(c) A number of vehicles, though not claimed by the pilots, were lost to the enemy by "indirect" air action (i.e. abandoned or destroyed by the crew).

another report:
As a result of the American break through (Operation COBRA), a retreating German column was attacked during the afternoon of 29 July by Rocket-firing Typhoons of 121 Wing, 83 Group and American Thunderbolts carrying 500 lb bombs. 99 sorties were made by 121 Wing.
It is not possible to state how long this particular German unit had been fighting as its name is not known but, on evidence of its abandoned equipment, it was a mixed column containing Panther tanks, SP guns, armoured troop carriers, lorry drawn A tk guns and howitzers, Pupschen rocket guns, armoured and staff cars.
According to local inhabitants the column was passing throughout the day and was joined by troops from the vicinity who looted as they left.
II. Terrain
The path of the German retreat in the area under consideration is shown in the appended map. It lay through country well dissected by deep narrow twisting valleys, much of the area being heavily wooded.
The side road which was used leaves the main road about 1 kilometre south of ST. DENIS LE-GAST (MR 315443) and descends rapidly to LA BALEINE where the River SIENNE is crossed. This road has a steep wooded cliff on one side and a sheer drop to the river on the other so that it was impossible for vehicles to draw off the road.
At LA BALEINE (MR 323427) the road crosses the river by a bridge which had been sufficiently damaged by 500 lb bombs dropped by Thunderbolts to prevent heavy traffic from crossing.
After crossing the bridge the road turns south, closely following the course of the river and a few feet above water level. On the east a densely wooded hill rises abruptly from the roadside making manoeuvre impossible. Half a mile down this stretch of the road (at point "A" on the attached map) the road twists sharply away from the river up a side valley. At this corner the road is well exposed to air observation and attack.
For the next quarter of a mile along the road as it climbs up towards the north east there is a fairly thick screening from the air, but just before the cross roads ("B") there is a short stretch that is much more open. At "B" the route followed by some, and perhaps all, the Germans turn south and continue to climb between high banks through farmlands and orchards. At several points along this stretch there are gaps in the road banks giving access to the fields.
To the east of "C" abandoned and destroyed vehicles were found along a fairly level road through fields with trees lining all the hedges and along a similar one turning south from it. As these roads are well outside the area attacked by the Typhoons the route was not examined further.
III. Details of Damage
(Note: Letters and numbers refer to points marked on the attached map.)
Point 1: Two camouflaged Panthers were placed in an orchard and facing the main road from ST. DENISLE GAST. They were probably in this position for several hours as there were signs that meals had been cooked. Craters caused by 500 lb bombs were seen within 50 yards of the tanks; these are thought to have been dropped by American Thunderbolts which are known to have been operating in the area. The tanks had not been hit but the crews apparently baled out, set fire to their tanks, and destroyed one of the guns by leaving an HE round in the chamber.
Point 2: A 75 mm SP with thick, concrete reinforcement of the turret was found pushed off the road by a Bulldozer. This SP was undamaged but 5 strikes from the air (cannon or machine gun) had made "cups" in the concrete. There was a 500 lb bomb crater 35 yards away. If the SP had been left to block the road it would have been set on fire by its crew; as it was not, the presumption is that it was abandoned in haste.
Points 3 and 4: Round about points 3 and 4 a number of 500 lb bomb craters were observed. At point 3 a Panther had been left on the road in perfect condition with full complement of petrol and ammunition. At, point 4 another Panther was found undamaged in every respect. If the commanders of these tanks had wished they could have travelled down the right hand bank of the stream and attempted a crossing as Shermans later succeeded in doing.
All along the river bank between point 2 and the bridge at LA BALEINE an assortment of "B" vehicles, all burnt out beyond recognition, had been pushed off the road by Bulldozers. A fair estimate would be eight vehicles (lorries and cars).
On the east side of the bridge a wrecked German saloon car was found at the foot of a 10 foot bank.
Point 5: A Panther was found to have been hit in the engine by a rocket projectile. It had brewed up.
Between the bridge and point 5 were a lorry towing a Howitzer and a saloon car; all three were completely wrecked and burnt out. RP strikes on the ground were numerous in this area.
One hundred yards south of Point 5 was another lorry towing a Howitzer; the lorry was a charred wreck but the Howitzer seemed to be undamaged.
A: Just north of corner A, by the edge of the wood, was a burnt out lorry which had been towing a 50 mm A tk gun. A Pupschen rocket gun was also found at this point; both guns were undamaged. At corner A, where many RP strikes were observed, was a Panther which had not been hit by anything and appeared to have been abandoned intact. Also at this corner were 5 armoured troop carriers (half tracks) which were all completely destroyed. RP was definitely responsible in one case and probably in all, but the damage was too great to allow accurate estimation.
Point 6: A troop carrying lorry was found burnt out; RP strikes were numerous in this area and the lorry was probably destroyed by this means.
Point 7: A Mark IV Special was found completely wrecked and pushed off the road; the great number of strikes in the immediate vicinity would suggest that it had been hit by RP.
A little further up the road were a saloon car and a lorry, both completely destroyed and burnt.
Point 8: A Panther was found wedged between a barn and a high bank; it also had stones in the tracks. A broken towing hook and tracks on the ground showed that another tank had tried to tow it and failed. This Panther had received no damage of any sort but was set on fire by the crew in the presence of the farmer.
In an orchard opposite Point 8 was a Volkswagen which had been hit in the engine by cannon or machine gun fire from the air.
A few yards up the road from Point 8 an armoured car (captured from the Americans and painted with German markings) had brewed up as a result of a hit in the engine. Although this looked like RP damage there were no strikes or debris anywhere near the point where the fire took place.
Point 9: A lorry was found burnt out; again there were no signs of rocket strikes.
In fields just off the road, at points marked x on the map, there were cars abandoned in various states of destruction. None of these had been hit by RP.
Point 10: A 75 mm SP gun was found burnt out but with no visible sign of the cause of the fire. A few yards away was a 50 mm A/tk gun, the breech of which had been deliberately destroyed.
Point 11: A Panther had an AP hit in the engine and another on the left driving sprocket; the left track was off. The gun had its barrel completely destroyed in the manner that suggested deliberate destruction on the part of the crew. This Panther had brewed up but the tyres were intact. It was a long way from the nearest area where rocket strikes were observed.
Throughout the area no German graves were found and only one German corpse, said by local inhabitants to have been that of a sniper shot subsequent to the passing of the column. It is possible that American forces had taken uhe dead to a distance to bury them but no proof or disproof of this could be found.
Many French civilians were examined in the area and their evidence confirmed the statements made in this report.
IV. Summary of Damage
The details of damage are summarised in the following table:
Note to Summary
The high proportion of abandoned Panther tanks to the total number of such tanks should be noted.
The MT was so mangled that identification of the causes of destruction was impossible; in consequence, the "unknown cause s" total has been unduly loaded. It would probably give a truer picture of events if the MT losses were spread over all the table in the same proportion as the other losses.
As a result of the American break through (Operation COBRA), a retreating German column was attacked during the afternoon of 29 July by Rocket-firing Typhoons of 121 Wing, 83 Group and American Thunderbolts carrying 500 lb bombs. 99 sorties were made by 121 Wing.
It is not possible to state how long this particular German unit had been fighting as its name is not known but, on evidence of its abandoned equipment, it was a mixed column containing Panther tanks, SP guns, armoured troop carriers, lorry drawn A tk guns and howitzers, Pupschen rocket guns, armoured and staff cars.
According to local inhabitants the column was passing throughout the day and was joined by troops from the vicinity who looted as they left.
II. Terrain
The path of the German retreat in the area under consideration is shown in the appended map. It lay through country well dissected by deep narrow twisting valleys, much of the area being heavily wooded.
The side road which was used leaves the main road about 1 kilometre south of ST. DENIS LE-GAST (MR 315443) and descends rapidly to LA BALEINE where the River SIENNE is crossed. This road has a steep wooded cliff on one side and a sheer drop to the river on the other so that it was impossible for vehicles to draw off the road.
At LA BALEINE (MR 323427) the road crosses the river by a bridge which had been sufficiently damaged by 500 lb bombs dropped by Thunderbolts to prevent heavy traffic from crossing.
After crossing the bridge the road turns south, closely following the course of the river and a few feet above water level. On the east a densely wooded hill rises abruptly from the roadside making manoeuvre impossible. Half a mile down this stretch of the road (at point "A" on the attached map) the road twists sharply away from the river up a side valley. At this corner the road is well exposed to air observation and attack.
For the next quarter of a mile along the road as it climbs up towards the north east there is a fairly thick screening from the air, but just before the cross roads ("B") there is a short stretch that is much more open. At "B" the route followed by some, and perhaps all, the Germans turn south and continue to climb between high banks through farmlands and orchards. At several points along this stretch there are gaps in the road banks giving access to the fields.
To the east of "C" abandoned and destroyed vehicles were found along a fairly level road through fields with trees lining all the hedges and along a similar one turning south from it. As these roads are well outside the area attacked by the Typhoons the route was not examined further.
III. Details of Damage
(Note: Letters and numbers refer to points marked on the attached map.)
Point 1: Two camouflaged Panthers were placed in an orchard and facing the main road from ST. DENISLE GAST. They were probably in this position for several hours as there were signs that meals had been cooked. Craters caused by 500 lb bombs were seen within 50 yards of the tanks; these are thought to have been dropped by American Thunderbolts which are known to have been operating in the area. The tanks had not been hit but the crews apparently baled out, set fire to their tanks, and destroyed one of the guns by leaving an HE round in the chamber.
Point 2: A 75 mm SP with thick, concrete reinforcement of the turret was found pushed off the road by a Bulldozer. This SP was undamaged but 5 strikes from the air (cannon or machine gun) had made "cups" in the concrete. There was a 500 lb bomb crater 35 yards away. If the SP had been left to block the road it would have been set on fire by its crew; as it was not, the presumption is that it was abandoned in haste.

I remember seeing a History Channel show about 9th AF P47's figuring out how to disable a tank by aiming at the ground just in front of the tank and letting the richochette's penetrate the unarmoured bottom.
Dont know if its true.

I like to think of this as one of those great enduring myths of WW2 aviation.
When you actually analyse it though, it turns out to be impossible.
Most WW2 tanks were more heavily armoured on their undersides than people realise. Designers generally gave their tanks some degree of protection to anti-tank mines, which meant heavy floor armour.
Panzer IV had around 85mm on is undersurfaces.
Panzer V (Panther) had around 90mm on its undersurfaces
Panzer VI (Tiger) had between 26mm and 90mm on its undersurfacces
The best penetration for a WW2 vintage M2 firing AP ammo is about 27mm at 90 degrees at 200 meters. The best penetration for API ammo is about 22mm at 90 degrees at 200m. If you add the extra velocity of a plane doing 350 mph then you can add about 155m/sec. This puts the inital velocity of a M2 AP round up from about 890m/sec to 1045m/sec, an increase of about 15%. That is going to add a maximum of about 3-4mm penetration
So, even a point blank shot against the lower hull, with no deflecting angle, adding the extra initial velocity, is not going to penetrate the armour plate on the bottom of a WW2 era tank.
You also have to consider a few other factors.
1. The drop in velocity when the bullet strikes the ground. This will rob the round of about 10-15% of its speed.
2. Round deformation when it hits the ground. Firing a .50cal round at a concrete or ashphalt surface is going to seriously mess up the claen shape of the projectile. That in turn will reduce the armour piercing capabilites of the round.
3. Angle of impact. In order to skip a round up into the belly of a tank, you would have to fire it at an oblique angle. So the round is not going to hit at the desired 90 degrees, but rather at something more like 30 degrees. This means that the bullet would have to pass through about 75% more armour to gain a penetration, if it wasn't deflected in the first place.
The one video I have seen of pilots refering to skipping rounds up into the underside of tanks is not actually referance to pazers at all. Rather it was a 9th AF straffing film where pilots would fire at the towed fuel tanks that Tigers often pulled along with them. The top and sides of the fuel tanks were armoured, but the undersides weren't. So the pilots would hit the fuel tanks, causing a nice explosion and hopefully getting a soft kill on the Tiger by pouring flaming gasoline into the engine vents.
