Anglo-French Relations Before the Second World War [PDF ebook] 
Appeasement and Crisis

Despite their shared underlying interests, Britain and France, the only powers in a position to effectively meet the first overt challenges to the European order established after 1918, ignominiously failed in the management of the crises facing them in Ethiopia and the Rhineland. In this book the author attempts to understand the (mal)functioning of the Anglo-French relationship at this key juncture on the path to the second world war.
