Consists of unbound typed diary entries, documents and letters relating to Lester's final months as High Commissioner of the League of Nations in Danzig. Lester left Danzig on 22 December 1936 having been promoted to the position of Deputy Secretary General of the League. He took up his new appointment in Geneva on 16 January 1937. Includes document written by Lester outlining the context for the file: 'The following fragments are the only notes I have of my last six months in Danzig ... The reason they are so fragmentary ... was that the crisis in Danzig developed so quickly and in such uncertainty that I could not safely keep any record of certain matters, either in my house or my Office. For three months at any rate I was not at all sure that my house and Office might not be occupied any day by the political Police or the Storm Troopers [sic].' - Document comprising of two diary entries, the first from 6 May 1936 (pages 1-3) and the second from early July 1936 (pages 4-9) combined together as a single entry. The section from 6 May 1936 is duplicated in Diary 2: January-June 1936 in the collection [diary C1/2]. Includes diary entries (some marked 'Private Diary') from the following dates: 8, 17, [?20], 23 (two entries with this date, one titled 'Relations with Greiser'), 24, and 28 July 1936; 3, 5, 6 and 7 August 1936 (two copies); 12 September 1936; 16, 19 and 24 October 1936; 22 December 1936 and 1 February 1937. Entries were all written in Danzig apart from the final entry (1 February 1937) which was written in Geneva. Includes undated notes on Albert Forster, the Nazi Party's Gauleiter in Danzig, that was originally filed between diary entries from 24 October 1936 and 22 December 1936, and was thus possibly written during that period.
