# 12th (Eastern) Division

The 12th (Eastern) Division was an infantry division raised by the British Army during the First World War from men volunteering for Kitchener's New Armies. The division saw service in the trenches of the Western Front from June 1915 to the end of the war.

## Formation and First World War

The 12th (Eastern) Division, was one of the first Kitchener's Army divisions raised from volunteers by Lord Kitchener. It was formed within Eastern Command as a result of Army Order No. 324 of 21 August 1914, as part of the K1 wave of divisions.
It fought on the Western Front for the duration of the First World War. One of its most notable actions was the Battle of Épehy where there is a memorial cross to the 12th Division.
In the First World War, the division's insignia was the Ace of Spades, which has since been adopted by the present 12th Armoured Infantry Brigade.
