The Battle of the Atlantic and Signals Intelligence


Book Description

This title was first published in 2002. This book contains the U-boats situations and trends written by the staff of the Admiralty’s Operational Intelligence Centre during the Second World War. Based largely on communications intelligence, the U-boat situations and trends were designed to inform a small number of senior officers and high officials of the latest events and developments in the Allied war against the U-boats. The Battle of the Atlantic and the war against the U-boats was the longest and the most complex naval battle in history. In this huge conflict which sprawled across the oceans of the world the U-boats sank 2,828 Allied merchant ships while the Allies destroyed more than 780 German U-boats. These documents relate on a weekly, and in some cases a daily, basis exactly what the Allies knew concerning the activities of the U-boats during the Battle of the Atlantic.




U-boat Intelligence


Book Description

The second book in Grant's trilogy covering the war against the U-boats shows how the Intelligence Division of the Admiralty played a key role in the defeat of the U-boats in World War I. With the assistance of the Naval Historical Branch of the Ministry of Defence and the Director of Naval History in Washington, Professor Grant has been able to piece together the crucial role played by naval intelligence in the victory at sea 1914-1918.

Effects on U-Boat Performance of Intelligence from Decryption of Allied Communication


Book Description

Examination of the War Diary of the German ComSubs has made it possible to estimate the character and extent of intelligence obtained by the decryption of Allied radio messages pertaining to convoy operations in the North Atlantic during World War II, and to determine the effect of such intelligence on the capability of the U-Boats to contact convoys and sink ships. It is estimated that the availability of timely usable decryption intelligence increased the contact rate twofold over that which they would have obtained without it; probably over 60 sinkings in excess of the expected number if they had been deprived of decryption intelligence. These calculations help in estimating a valid measure of the effectiveness of current and future submarines in anti-convoy operations when decryption intelligence is not available. (Author).
