Alf 'Cocky' Swayne served with the Waikato Mounted Rifles for four years prior to World War One. He enlisted on the 10th of August 1914, and proceeded overseas in the main body with the Auckland Mounted Rifles.
He fought at Gallipoli, spending 13 weeks there before being wounded on the 8th of August 1915. After recovering he was sent to France with the 1st Battalion Canterbury Infantry Regiment.
He was again wounded, at Messines in June 1917. He received a commission in the field, and was transferred to the 1st Battalion Auckland Infantry Regiment, again receiving wounds twice with this battalion.
Alf served with the Auckland Infantry Regiment until his discharge on the 11th of June 1919. He was a fully qualified Vickers Gunner and Lewis Gunner, and instructor in the use of both these guns and in throwing hand grenades. These old skills were revisited when he became an officer in the Home Guard.
