RAF Vickers Wellington bombers in flight somewhere over England in January 1941. The original caption to this image stated that these aircraft had been used in the 'first big raid of the war'. The most recent operation which might fit that description was the Mannheim raid of 16–17 December 1940, where Wellington bombers opened the attack by dropping incendiaries calculated to set the centre of the city alight. Australian aircrew came to know the Wellingtons well, the RAAF's first Bomber Command unit to fly them on operations being No. 458 Squadron RAAF on 20–21 October 1941 against Antwerp, Rotterdam and Emden.
