Letter from WSC to Lord Rothermere, on his sources of information for the size of the German air force. Stating that he believed that the Germans had a regular military air force, in violation of the treaty, of 300 aircraft, against Britain's home defence force of 350 aircraft, and that the Germans were increasing this total to 500 by the end of 1935. These figures took no account of German civil aviation, which was five times the size of Britain's, a large part of which was rapidly convertible into war machines. Stating that Rothermere's figure of 20,000 for the German air force could have no reality. Commenting that he felt it best to err on the side of under-statement, and that his figures could be increased later, "without any reproach". Stating that he intended to do his utmost in this matter, and that he was certain that they could "extort more vigorous action from the Government. Whether it will be to little or too late is a matter upon which I am glad not to have the responsibility. I feel a deep and increasing sense of anxiety" Also commenting on the work of the India Defence League, and the need for around £2000 for the league to continue until the Spring of 1935 [carbon].
