British Second Army (1916)
The I ANZAC Corps (First Anzac Corps) was a combined Australian and New Zealand army corps that served during World War I.
It was formed in Egypt in February 1916 as part of the reorganisation and expansion of the Australian Imperial Force and the New Zealand Expeditionary Force (NZEF) following the evacuation of Gallipoli in December 1915. Along with the II ANZAC Corps, it replaced the original Australian and New Zealand Army Corps (ANZAC). The corps initially participated in the defence of the Suez Canal before being transferred to the Western Front in France and Belgium in late March 1916. Later in 1916 the New Zealand Division was removed from I ANZAC's order of battle, swapping with II ANZAC's Australian 4th Division.
In November 1917, I ANZAC ceased to exist when the Australian infantry divisions in France were grouped together as the Australian Corps and the New Zealand Division, then part of II ANZAC Corps, was allocated to a British corps.
