Notes:
8/06/42: 139 Sqd., which had been overseas, was reformed at Horsham St Faith. The Sqd. was originally to re-equip with Blenheim V's, but fortunately, these aircraft were never used operationally 139 Sqd. became only the second Mosquito Squadron in 2 Group, RAF.
Sept.42: 139 Sqd. starts to get it's own Mosquitoes. (139 Sqd. had been borrowing aircraft from 105 Sqd.up to this point in time). By November 1942, 139 Sqd. was fully equipped with all it's own Mosquitoes.
31/05/43: 139 Sqd.leaves 2 Group, to become part of the 8 Path Finder Force (8PFF). 139 Sqd. would become the nucleus for the Light Night Striking Force (LNSF), which would eventually be made up of Mosquito Bombers ( other Mosquito Squadrons in the LNSF would include 627, 692, 571, 608, 142, 128, 162 163 Sdrs.). 139 Sqd. would now carry out high level nuisance bombing raids, but would eventually act as a marking squadron for the LNSF.
03/10/43: G-H used for the first time by a 139 Sqd. Mosquito B IX ML 908 (XD-Y). The G-H failed on this occasion but was used successfully to bomb Dortmund. 10/10/43.
01/02/44: H2S used by 139 Sqd. for the 1st time on The Big City (Berlin).
139 Sqd. became the first squadron to operate Mosquito B XVI's and on 02/03/44 2 Mosquito B XVI's,ML 941 (XD-N) ML 942 (XD-F),became the first B XVI's to drop a 4,000lb cookie. The target was Munchen Gladbach.
June 43 to May 45: 139 Sqd. completed 4187 operational sorties during this period with the LNSF. (225 operational sorties were carried out, when the Squadron was in 2 Group).
The last Mosquito was struck of squadron charge at end of 1952, having been finally replaced by Canberra bombers.
(214 different Mosquitoes were flown by 139 Sqd. from September 1942 to November 1953. The above are just a few examples)
