XII Corps was formed in France on 8 September 1915 under the command of Lt-Gen Sir Henry Fuller Maitland Wilson.[1][2] In November 1915, XII Corps was sent from France with 22nd, 26th and 28th Divisions under command to reinforce Allied forces on the Macedonian front. Wilson and his corps headquarters (HQ) arrived at the port of Salonika on 12 November, but the commander of the British Salonika Force (BSF) took XII Corp’s staff to establish his own HQ.[3] On 14 December 1915 the War Office sanctioned the establishment of two corps within the BSF and Wilson reformed XII Corps.
