"I have decided to prepare for, and if necessary to carry out, an invasion against England."--Adolph Hitler, July 16, 1940
Operation Sealion was the codename for the Nazi invasion of Britain that Hitler ordered his generals to plan after France fell in June 1940. Although the plan ultimately never came to fruition, a few sets of the Germans' detailed strategy documents are housed in the rare book rooms of libraries across Europe. But now the Bodleian Library has made documents from their set available for all to peruse in this unprecedented collection of the invasion planning materials.
The planned operation would have involved landing 160,000 German soldiers along a forty-mile stretch of coast in southeast England. Packets of reconnaissance materials were put together for the invading forces, and the most intriguing parts are now reproduced here. Each soldier was to be given maps and geographical descriptions of the British Isles that broke down the country by regions, aerial photographs pinpointing strategic targets, an extensive listing of British roads and rivers, strategic plans for launching attacks on each region, an English dictionary and phrase book, and even a brief description of Britain's social composition.
Augmenting the fascinating documents is an informative introduction that sets the materials in their historical and political context. A must-have for every military history buff, "German Invasion Plans for the British Isles, 1940" is a remarkable revelation of the inner workings of Hitler's most famous unrealized military campaign.

A noted World War I scholar examines the critical decisions and events that led to Germany's defeat, arguing that the German loss was caused by collapse at home as well as on the front. Much has been written about the causes for the outbreak of World War I and the ways in which the war was fought, but few historians have tackled the reasons why the Germans, who appeared on the surface to be winning for most of the war, ultimately lost. This book, in contrast, presents an in-depth examination of the complex interplay of factors-social, cultural, military, economic, and diplomatic-that led to Germany's defeat. The highly readable work begins with an examination of the strengths and weaknesses of the two coalitions and points out how the balance of forces was clearly on the side of the Entente in a long and drawn-out war. The work then probes the German plan to win the war quickly and the resulting campaigns of August and September 1914 that culminated in the devastating defeat in the First Battle of the Marne. Subsequent chapters discuss the critical factors and decisions that led to Germany's loss, including the British naval blockade, the role of economic factors in maintaining a consensus for war, and the social impact of material deprivation. Starts a new and fuller discussion of Germany's defeat that goes beyond the battlefields of the Western Front Argues that Germany's defeat was caused by a complex interplay of domestic, social, and economic forces as well as by military and diplomatic factors Integrates the internal problems the German people experienced with Germany's defeats at sea and on land Highlights the critical role played by Britain and the United States in bringing about Germany's defeat Discusses the failures of German military planning and the failure of the nation's political leaders and military leaders to understand that war is the continuation of diplomacy by other means
