It was Louis Allen’s work on Japan which dominated his prodigious output as a scholar, researcher and writer and which received greatest attention internationally. This collection of his writings focuses entirely on his principal fields of research, viz, Japan and the Pacific War, the post-war conflicts in Burma, Malaya and Indochina, and the immediate post-war years in the context of Japan, security and reconciliation. Importantly, in addition to the 24 essays brought together here from both known and unknown sources, we are pleased to publish for the first time Louis Allen’s own undated autobiographical paper entitled ‘Innocents Abroad: Investigating War Crimes in South-East Asia’, providing a unique, first-hand account of his war-time life and activities. This volume also includes a complete bibliography of Louis Allen’s writings covering all disciplines.
