British War Production

Fighter output for July is found to be 50% above the target figures. Since May 1 1200 have been produced. This is more than have been made in Germany and the RAF is therefore closing the Luftwaffe's advantage.


German Raiders

The German armed merchant cruiser Pinguin sinks the British steamer Domingo de Larringa (5358t) in the South Atlantic. 8 of the crew are lost and 30 are made prisoners of war.

Germany, Planning

Hitler calls a meeting of the top officers of the navy to discuss the situation. Adm Raeder, the Commander-in-Chief, gives a detailed exposition of the difficulties of crossing the Channel with the means at present available to him. In his judgment it would be expedient to postpone Operation Sealion from September 13 to a date between September 19 and 26 to take advantage of favorable tides, and above all to limit the operations to the Straits of Dover. Finally, he comes back to the idea he has often expressed before, that the operation should be postponed until next spring.

Hitler also presents his plans for the invasion of the USSR to the OKH, the German Army High Command, and OKW, Armed Forces High Command. Speaking of increased Soviet strength along the eastern frontier, Hitler believes that Stalin has further territorial ambitions in the Balkans, namely the Romanian oil fields. Hitler then expands by claiming that Stalin's aims are no different from those of Peter the Great two centuries earlier, namely the conquest ot Poland, Bulgaria, Finland and the Dardanelles. War with the USSR is thus inevitable. In addition, he believes that defeating the Soviet Union will further weaken Britain because, with the Soviet Union laid low, Japan will be able to gain hegemony in the Far East. This in turn will focus the United States' attention on the Pacific region to the detriment of Britain. 'If Russia is laid low, then Britain's last hope is wiped out, and German will be master of Europe and the Balkans.'

Accepting that an attack cannot now take place before spring 1941, Hitler states that the army will be expanded to 180 divisions, 120 of whih will be in the East by the spring. Neither von Brauchitsch nor Halder offer any objectives to these plans.

United States, Home Front

Secretary of War Stimson calls for military conscription in the U.S. He says, 'Today we are face to face with a potential enemy which not only has been conscripting and training its own forces for the past six years but which today is putting conscription into effect upon its victims in Poland and France, and in Norway, Denmark, and Holland, in order that its own war supplies may be more ample.' Privately, Stimson feels that Britain will fall within a month.
