First published in 1979. In this text the Adamthwaite aims at leading students through the maze of documentation surrounding the Second World War. His book combines a critical assessment of recent research and writing with a painstaking selection of the key documents needed for a clear understanding of the policies that led to war. It contains the first student selection of British, French, German, Italian and Soviet documents, many of which are translated for the first time. Though emphasis falls on the years 1935-9, material is also included for the period 1929-35.
