A very historical collection of Diaries and Documents to a naval man involved initially in anti U boat Patrols and then in the collection of Nazi U boats - which were taken to Scotland. It was during such encounters that the British obtained the German Enigma machine and learnt much about U boats and so these diaries are rare and important on an international level, the diaries cover from mid 1941 to the end of the war, they detail many patrols during which the author, John Sellors, served. On one he States that Winston Churchill is on one boat in the patrol heading to America to meet Roosevelt. In other entries he States they are looking for and shadowing the Bismarck. In his day by day accounts he discusses the hunt for U boats, dropping depth charges on them and even picking up on one occasion over 100 survivors for return to England as Prisoners of war, after the end of the war, large numbers of captured German U-boats were surrendered to British Forces on the Scottish and Irish coasts and were brought to Lisahally, the American base had been transferred to the Royal Navy on 31 October 1944, the site was commissioned in May 1945 as Hms Ferret IV specifically for the internment. Eventually nearly sixty U-boats were brought in to Ferret IV, after a period of study and other trials many were sunk of Lisahally and Loch Ryan during late 1945 and 1946 in Operation Deadlight, after this had been completed Ferret IV was paid Off to care and maintenance on 19 July 1946. John Ernest Sellors was born in Derby in 1900. He enlisted in the Royal Navy in 1919, narrowly missing the conclusion of World War I. He remained in the Royal Navy and then the Royal fleet Reserve until the outbreak of World War II when he was called up for war service. During the war he served on ships such as Eaglet, Cochrane II and Ferret. Included with the lot is his original parchment Certificate of service.
