VIDEO: The centenary of the Battle of Cambrai
Tanks are as relevant in current warfare as they were 100 years ago at the Battle ofÂ Cambrai, an Army commander has said.
During the First World War 476 British tanks spectacularly broke through enemy lines in Cambrai, north-eastern France, during a major offensive which began on November 20 1917.
Although this was not the first time tanks had been used in battle, the attack, which ended on December 6 1917, marked the first time they had been deployed in significant numbers
To mark the 100th anniversary of the Battle of Cambrai, the oldest tank unit in the world shows their main battle tank, the Challenger 2.
