ND 474 took off from RAF Fiskerton at 19:05 and was the third aircraft to leave the airfield. The main raid to Stuttgart consisted of 863 aircraft - 617 Lancasters, 230 Halifaxes, 16 Mosquitos - all from different squadrons based in and around Lincolnshire.
At 20:05, five minutes after the formation of bombers flew across the coast of France, the German fighter controller had been altered and had split his forces into two parts. The bomber force flew over France nearly as far as the Swiss frontier before turning north-east to approach Stuttgart.
This delayed the German fighters contacting the bomber stream but, when the German fighters did arrive, just before the target was reached, the usual fierce combats ensued.
37 aircraft - 27 Lancasters, 10 Halifaxes - were lost, 4.3 per cent of the force. 2 of the Lancasters force-landed in Switzerland. Adverse winds delayed the opening of the attack and the same winds may have been the cause of the Pathfinder marking falling back well short of the target, despite the clear weather conditions. Some of the early bombing fell in the centre of Stuttgart but most of it fell in open country south-west of the city. The Akademie was damaged in the centre of Stuttgart and some housing was destroyed in the south-western suburbs.
