1000 RAF bombers target Cologne
30th May 1942: Operation Millennium, the largest bombing raid the world had yet seen, overwhelms the defences of a major German city and sees one Victoria Cross
RAF Bomber Command’s shift to ‘area bombing’ had already wrought devastation on the the cities of Lubeck and Rostock. Their destruction had sufficiently disturbed the Nazis to see them launch the retaliatory ‘Baedecker’ raids on Britain’s historic cities. But the head of Bomber Command, Arthur ‘Bomber’ Harris1 wanted to mount an even more shocking attack:
There remained the problem of the first-class target, the major industrial town round which the enemy was bound to concentrate effective and heavy defences. So far all that the Lubeck and Rostock attacks had proved was that we could saturate the passive defences of a town by concentration of attack; it remained to be seen whether the active and passive defences of a vital industrial area could be similarly overcome.
In order to achieve this he planned to use a much larger number of bombers to overcome the defences of an industrial target. By scraping together all the available bombers in service, including a number from training establishments, he found more than a 1000 aircraft. It was a figure that would ensure that Operation Millennium got plenty of attention around the world.
