On 15 September 1916 during the Battle of the Somme, tanks - one of the decisive weapons of twentieth-century warfare - were sent into action for the first time. In his previous books Trevor Pidgeon, one of the leading authorities on the early tanks, has told the story of that memorable day, but only now has his account of later tank operations during the Somme battle become available. In this, his last work which was completed shortly before he died, he reconstructs the tank actions that took place between late September and November when the Somme offensive was closed down. His account gives a vivid insight into the actions and experiences of the tank crews, and it shows the appalling dangers they faced as they maneuvered their crude, vulnerable and unreliable machines towards the enemy. His book will be essential reading for anyone who is familiar with his previous studies of the subject and for anyone who wants to follow in the tracks of the tanks as they lumbered across the battlefield nearly 100 years ago.
