27th Division (United Kingdom)

The British 27th Division was a First World War regular army infantry division formed in late 1914 by combining various units that had been acting as garrisons about the British Empire. The division spent most of 1915 on the Western Front in France before moving to Salonika where it remained with the British Salonika Army for the duration of the war. In 1916 its commander Hurdis Ravenshaw was captured by an Austrian submarine whilst sailing to England. In 1918 in Salonika the division took part in the Battle of Doiran.
