After a career in the diplomatic service Trevor Pidgeon devoted much of his time to pioneering research into the Great War, in particular into the development of tanks and the operations of the first tanks on the Western Front. His work lead to several books that were milestones in the field, including his classic study Tanks at Flers: An Account of the First Use of Tanks in War at the Battle of Flers-Courcelette, the Somme, 15 September 1916.
Trevor Pidgeon sadly died in 2008 and his last book, Tanks on the Somme, was completed by his friend Dr Graham Keech.

The principal action that took place here in February 1917 was of short duration and failure but with fascinating overtones. This is the dramatic story of the events on the Somme after the great battle of 1916 ended and before the Germans withdrew to the Hindenburg Line. Its focus is on a ravine easily as impressive as that at Beaumont Hamel.
