The First World War, 1914 - 1918

The First World War 

Two HAC infantry battalions and five artillery batteries were mobilised for active service overseas during the First World War.  After the outbreak of war on 4 August 1914, the existing half Infantry Battalion was brought up to full strength and became the 1st Battalion, serving in France and Flanders from 18 September 1914.  The 2nd Battalion was raised in September 1914 and sailed for France on 1 October 1916 and saw active service in France, Flanders and Italy. The Reserve (or 3rd) Battalion supplied the other two Battalions with drafts from England.

The existing A and B Batteries of horse artillery were brought up to strength and sailed for Egypt on 9 April 1915, serving both separately and together there and elsewhere in the Middle East.  The 309th (HAC) Siege Battery of the Royal Garrison Artillery and the two second-line horse artillery batteries, 2/A Battery and 2/B Battery, saw action in France and Flanders from April and June 1917 respectively.  The three (later two) reserve batteries remained in England.

Around 13,000 members served with the HAC during this war and over 4,000 of these men were commissioned into other units. The Company’s casualties during this conflict totalled about 1,650 men who died serving either with HAC or other units of the armed forces.
