The Royal Tank Regiment, the oldest tank unit in the world, will commemorate 100 years since the Battle of Cambrai

The Battle of Cambrai took place between 20 November and 6 December 1917. It was the first time that tanks had been used in significant numbers, with over 450 deployed. The battle is also widely recognised as the first time that UK and US soldiers fought and died together in conflict, as US Army engineers were attached to support the British attack.
