The War Cabinet papers contain mainly printed material, and some notes and correspondence, arising from WSC's positions, as First Lord of the Admiralty, from 3 September 1939 to 9 May 1940, and then as Prime Minister and Minister of Defence, from 10 May 1940 to 23 May 1945. Up to May 1940, the papers relate to the general conduct of the war, outside the departmental responsibility of the Admiralty. After that date, general papers are to be found in CHAR 20 (Official: Prime Minister), and CHAR 23 is almost wholly taken up by printed material, chiefly Prime Minister's Directives, and records of the Chiefs of Staff Committee, arranged chronologically.Subjects include: the general conduct of the war; defence; army, navy and air operations; relations with the United States and Soviet Union; food production; the war in the Far East; records of the conferences at Quebec, [Canada], Washington [United States], Malta and Yalta [Soviet Union]; the occupation of Germany; the future of Yugoslavia [later Bosnia and Herzegovina, Croatia, Kosovo, Montenegro, North Macedonia, Serbia, and Slovenia]; the future of Poland; the establishment of the United Nations; post-war civil aviation; post-war reconstruction; the Emergency Business Committee, set up for the General Election.
