This comprehensive boxed set brings together two expertly written accounts of the histories of World War I and II. Each book covers all aspects of the war, including detailed analyses of decisive encounters, and profiles of important political and military figures, as well as an exploration of the staggering human cost of the war and the experiences of those who lived through it. Blow-by-blow accounts of the two wars take the reader through the battles, campaigns and fighting from the viewpoints of the different participants. With the first book setting the immediate historical context, it becomes clear to see how the impact of World War I led to the simmering and dangerous climate of Nazi Germany and the actions that led to the outbreak of World War II, one of the most devastating wars in the history of global conflict. Throughout both volumes, it is demonstrated how military technology and tactics progressed and developed, from trench warfare using heavy field artillery through to the Blitz and ultimately to the dropping of the atom bomb on Hiroshima in August 1945. All the major events are vividly portrayed through engaging and informed narrative, illustrated with over 1000 historical photographs, specially commissioned maps, plans and diagrams. In addition, insightful anecdotes illuminate this fascinating history of the two world wars and make this an accessible, highly readable box set for both the general and specialist reader.
