The 73rd Division in 1914-1918

The history of 73rd Division

This formation was created during the war. Late in 1916 orders were given for the formation of three additional home-service Divisions; they would have the dual role of carrying out training of men for overseas drafts, plus providing forces for home defence. 73rd was one of the three Divisions formed, and was initially established in Blackpool. It moved between 5-18 January 1917 to Essex and Hertfordshire, with HQ being at Boreham House near Chelsford. The Division came under command of Southern Army, Home Forces. On 21 December 1917 orders were received that the Division should be broken up. Disbandment began in January 1918 and the final elements disappeared on 8 April 1918.

On 1 January 1917 the Provisional units were all retitled, as shown in the Order of Battle below.

A number of non-regimentally-affiliated Graduated Battalions joined in July 1917. They were affiliated and retitled on 27 October 1917.
