Churchill viewed the fall of Singapore to be "the worst disaster and largest capitulation in British history." However, the British defence was that the Middle East and the Soviet Union had all received higher priorities in the allocation of men and material, so the desired air force strength of 300 to 500 aircraft was never reached, and whereas the Japanese invaded with over two hundred tanks, the British Army in Malaya did not have a single tank. In "The War in Malaya" Percival himself cites this as the major factor for the defeat stating that the 'war material which might have saved Singapore was sent to Russia and the Middle East'. However he also concedes that Britain was engaged in 'a life and death struggle in the West' and that 'this decision, however painful and regrettable, was inevitable and right'.
