There is some food for thought in that article...
Leaning Forward - Rhubarbs
Some here have written that the British tactic/strategy of "leaning forward" and performing Rhubarbs was disastrous, or at least unsuccessful.
But it appears that the Germans were doing the same, or similar, over Britain.
Locomotive damage repair
It is also interesting how quickly the severe damage to the locomotive was repaired and the unit returned to service.
We know that Allied fighters shot up a lot of locomotives in Europe.
This makes me wonder how quickly those were repaired and returned to service.
Of course, in the battle of attrition, the Germans could less afford the cumulative effect of such attacks.
Regardless, such factors figure into the cost/benefit of Allied strafing missions.
