XI Corps (United Kingdom)
|Sir Richard Haking|
XI Corps was a corps-sized formation of the British Army, active during the Great War that served on the Western Front and in Italy. It was recreated as part of Home Forces defending the United Kingdom during World War II.
First World War
XI Corps was formed in France on 29 August 1915 under Lt-Gen Richard Haking. Its first serious engagement (as part of Sir Charles Monro's First Army) was the Battle of Fromelles (19 July 1916), a diversion to the Somme offensive in which two untried divisions were launched into an ill-planned subsidiary attack in Flanders. It achieved nothing but cost thousands of casualties, and caused great resentment in Australia.
