The Tiger and the Churchill are two of the most recognizable heavily armoured tanks of World War II. Both were designed hastily in the early years of the war, and both witnessed inauspicious debuts in battle in August 1942 (the Churchill in the disaster at Dieppe, the Tiger near Leningrad). Despite their heavy weight, both tanks, which were intended to serve in breakthrough operations, had surprisingly good tactical mobility. Yet there were key differences between them too, chiefly in the effectiveness of their main armament. This fascinating and detailed work explores the design and development of these famous tanks and its influence on their head-to-head encounters, the effectiveness of the support services each tank relied upon, and the skills and experiences of the crews that fought in them. The specific battlefield conditions of Normandy in June and July 1944 are also examined, exploring the effect they had on the duels between these two heavyweight AFVs.
