The Battle of the Somme was both the largest battle on the Western Front of World War I and one of the deadliest in history, with more than a million casualties. The plan was laid at the Chantilly Conference in December 1915 - the Allied forces would take the pressure off French forces at the Battle of Verdun by pushing through the German lines at the Somme.
As with many grueling World War I encounters the battle was neither conclusive or quick. The first day of the battle - 1 July 1916 - was the bloodiest day in the history of the British Army, with more than 57,000 casualties.
While the Allied forces had pushed 10km (6 mi) into German territory by the battle's end, they had not seized the French towns of Péronne or Bapaume, and debate exists over whether the battle was necessary or militarily significant.
The tank was first premiered at the Somme - although early units could only go 4 miles (6 km) per hour and often broke down.
