Took off from RAF Witchford at 18:50hrs to join a massive attacking force of 734 aircraft made up from 460 Lancasters, 169 Halifaxes and 11 Mosquitoes to attack the German main production area of ball bearings.

The plan was to split the force into two halves separated with a 2 hour interval. This did work with 22 aircraft being lost on the first raid but half that number on the second and the majority of losses on the second wave were caused by flak.

362 People were killed on the ground from this raid and one from the previous night by American bombers.

LL701 was official posted as lost without a trace. However, an entry in the German night fighter logs for the night of the 24th/25th February 1944 has come to light and records a 115 Sqn Lancaster serial LL701 as being lost in the North sea, cause unknown. (Further research is being undertaken)

Two aircraft from 115 Squadron were lost on this operation, the other:

Lancaster LL644 KO-N flown by 22 year old, Fg.Off. Ronald Frank Nice 138588 RAFVR from Hornchurch, Essex, England - killed along with all other 6 crew members.
A 4-Mot was claimed by Lt. Hans Raum, his 5th victory, from 9./NJG3 nr. Würzburg: 6500m at 01:32. The aircraft was either LL644 or 463 Sqn Lancaster LM444. (Nachtjagd Combat Archive (1 January - 15 March 1944) Part 1 - Theo Boiten)
