Naval Control of Shipping and the Atlantic War 1939-45
A detailed description of the structure and method of operation of the Canadian Naval Control of Shipping (NCS) prior to and during WW2. NCS was responsible for the organization, planning and routing of merchant convoys in the Atlantic west of 40° and north of the equator. This also entailed intelligence gathering on enemy deployment as well as friendly shipping. The work of NCS is illustrated by a detailed account of the handling of a cargo carrier from its arrival at Halifax to its eventual departure as part of an east-bound convoy.
