materiel. This did not stop those outside the Chiefs of Staff questioning the strategic bombing policy. A particularly damning speech had been delivered in the House of Commons by the Member of Parliament for the University of Cambridge, Professor A. V. Hill—the noted research scientist and previously a member of the committee that had sponsored research into radar. His speech pointed out that In response to the concerns raised by the Butt report, Cherwell produced his dehousing paper (first circulated on 30 March 1942), which proposed that by area bombing instead of futile attempts at precision bombing the deficiencies of the RAF could be mitigated. The Secretary of State for Air, Sir Archibald Sinclair and Sir Charles Portal were delighted by the paper as it offered support to them in their battle to save the strategic bomber offensive, which had been under attack from others in the high command who thought that the resources put into Bomber Command were damaging the other branches of the armed services, with little to show for it. On reading the dehousing paper, Professor Patrick Blackett, the chief scientist to the Royal Navy, said that the paper's estimate of what could be achieved was 600 percent too high. The principal advocate for the reduction of Bomber Command in favour of other options was Sir Henry Tizard. He argued that the only benefit to strategic bombing was that it tied up enemy resources defending Germany but that those forces could be tied up with a far smaller bombing offensive. He wrote to Cherwell on 15 April querying the figures in the paper and warning that the War Cabinet could reach the wrong decision if they based their decision on it. His criticism of the paper was that experience suggested that only 7,000 bombers would be delivered rather than the 10,000 in the paper, and since only 25 percent of the bombs were likely to land on target the total dropped would be no more than 50,000, so the strategy would not work with the resources available. Mr. Justice Singleton, a High Court Judge, was asked by the Cabinet to look into the competing points of view. In his report delivered on 20 May 1942, he concluded that In the end, thanks in part to the dehousing paper, it was this view which prevailed but C. P. Snow (later Lord Snow) wrote that the debate became quite
