Ironside, Field Marshal Sir Edmund (1880–1959),British army officer who served as
Chief of the Imperial General Staff (CIGS) from 3 September 1939 to 27 May 1940.
In 1938 Ironside became governor of Gibraltar, expecting it to be his last post before retirement. But in May 1939 the war minister,
Hore-Belisha, appointed him Inspector General of Overseas Forces and on 3 September Ironside succeeded
Gort as CIGS. He soon proved as temperamentally unsuited to this task as his immediate predecessor, whose dislike of Hore-Belisha he shared. He chafed at the government's inactivity during the
phoney war and supported plans for cutting off German iron ore supplies that precipitated the ill-fated
Norwegian campaign. His assessments of Hitler's plans in the west, and the Allies' ability to counter any offensive, were inadequate and he proved unequal to the task of pleasing Churchill when the latter became prime minister on 10 May 1940. He was replaced by
Dill and made C-in-C Home Forces, a post he held for under two months before he was succeeded by
Brooke, promoted field marshal, and retired. He was knighted in 1919 and created a baron in 1941.
