Peter Schenk 
Operation Sealion [PDF ebook] 
The Invasion of England 1940

An in-depth analysis of Nazi Germany’s unused strategy to invade the UK during the Battle of Britain in World War II. It is hard to believe that in the summer of 1940, neither the Allies nor the Axis powers had any experience of large amphibious operations. German planning for Operation Sealion was concerned with pioneering new techniques and developing specialized landing craft. Remarkably, in only two months they prepared an invasion fleet of 4, 000 vessels. In Operation Sealion, Peter Schenk begins by examining the vessels that were developed and deployed for the operation: converted cargo vessels and steamers, more specialized landing craft, barges and pontoons, and auxiliary vessels such as tugs and hospital ships. He then goes on to outline the strategic preparations for the landing and looks at the operational plans of, in turn, the navy, army, and air force. The planned invasion is described in full detail so that the reader can follow the proposed sequence of events from loading, setting sail, and the crossing of the English Channel, to the landing and the early advances into southern England. Schenk uniquely estimates the chances of success. This absorbing account of Hitler’s abortive mission, more detailed than anything written before, is of interest not just to the naval historian but to anyone with an interest in World War II or military strategy.
