For most of World War II, British tank development remained faithful to the design philosophy inaugurated during World War I.

Experiences in North Africa highlighted flaws in this basic design, however, and the General Staff identified the need for a new heavy cruiser that could combine speed and manoeuvrability with increased armour and armament. The Cromwell Cruiser tank was designed as a result and soon proved itself one of the fastest and most successful tanks deployed by the Allies during World War II.

This book details the design and development of the Cromwell and its many variants, from its introduction at D-Day, through its many successes in the final year of World War II and beyond.
