A detailed study of the Medium Mark A Whippet - Britain's most successful tank of World War I.

The evolution of the Whippet is examined in detail, from design and development to mechanical details and crew duties, and information on the operational use of the vehicle is drawn from war diaries and battalion records. David Fletcher explores how the Whippet was involved in several well-known incidents: from the clash at Cachy on April 24, 1918, and actions of the 6th Battalion tank known as "Musical Box" on August 8, 1918, to Sewell's Victoria Cross-winning exploits with the 3rd Battalion on August 29, 1918 and the Tank Corps' expedition to Russia.

In addition to this examination of the Mark A Whippet, this illustrated study also features coverage of other Medium tanks up to the end of the war: the Medium B, Medium C, Medium D and the experimental American Studebaker tank.
