U-Boats Against Canada: German Submarines in Canadian Waters by Michael L. Hadley-German submarines penetrated Canadian waters to within 172 miles of Quebec City. After sinking ships, placing landmines, and attempting to rescue German POWS they forced Canada to close the St Lawrence River. The author Michael L. Hadley reveals the military and political impact on Canada. He vibrantly documents the successful German strategy of deploying daring long-range solo sorties to pin down the enemy close to home. Especially the stories of the espionage missions, where spies and equipment landed on Canadian and American shores from U-boats, and performed intelligence operations, especially "routine" ones like setting up weather stations in hostile territory. The author Hadley is a Captain in the Canadian Navy was chairman of the Department of Germanic studies at the University of Victoria. This hardcover book was published by McGill-Queen's University Press. This is the reprinted edition from 1985. It contains 381 pages and 39 black and white photos. The book itself is in very good condition, with a tight binding and a dust cover that is in very good shape. This is a very interesting book on a topic that does not have enough material written about it.
