This Naval Staff History describes the vital role of the Arctic Convoys, 1941-1945 and was first issued by the Historical Section of the Admiralty as a confidential study for use within the Royal Navy in 1954. It grew out of the earlier Battle Summary No. 22 compiled by Commander J. Owen of the Admiralty’s Historical Section and issued in 1943 to cover the convoys run to North Russia in the last half of 1942 and early 1943. That wartime Battle Summary was subsequently revised and expanded by Commander L.J. Pitcairn-Jones to include all the main convoys run from August 1941 until the end of the war using all the historical records which were at hand after the war. A new preface provides additional context for the convoys, highlighting support provided to Russian forces in their struggle against Germany, for the original Staff History was narrowly focused on the naval aspects of the Arctic Convoys to Russia. This is an excellent resource for all students with a particular interest in the Arctic Convoys, the Second World War and in maritime and military history.
