The Valentine was the most produced and most widely used British tank of the Second World War. The Valentine first saw combat during Operation Compass in November 1941 and remained one of the main medium tanks in British service into 1943. As the Churchill became more prevalent the Valentine was relegated to specialist and tank-destroyer variants, which would remain in service in the Far East to the end of the war. This book describes the evolution of the Valentine design and weighs up its impact on the battlefield. Although widely regarded today as one of the weaker tanks to be fielded during the war, it was exceptionally numerous, with more Valentines produced than any other British tank.
