Born on 26 August 1889 in Hawera, a small town in the Taranaki region of New Zealand, Grant was working as a builder when he volunteered for the New Zealand Expeditionary Force (NZEF) in June 1915. At the time of Grant"s enlistment, the NZEF was engaged in the Gallipoli Campaign and after initial training, he embarked for the Middle East in October 1915. He joined the 1st Battalion, Wellington Infantry Regiment of the New Zealand Division, then being formed in the aftermath of the evacuation from the Gallipoli Peninsula.
lieutenant duly embarked for the Western Front.
Grant served with the battalion throughout 1916 and 1917, and the following year had reached the rank of sergeant. He was 29 years old when he performed the deed for which he was awarded the On 1 September 1918 near Bancourt, the leading waves of the battalion on reaching a crest of high ground, found that a line of enemy machine-gun posts offered a serious obstacle to further advance.
The company, however, advanced against these posts under point-blank fire, and when about 20 yards (18 m) away Grant, closely followed by a comrade, rushed ahead of his platoon, entering the centre post and demoralising the garrison so that the platoon were able to mop up the positions. In the same manner he rushed the post on the left and the remaining posts were quickly occupied and cleared by his company.
Shortly afterwards, Grant was promoted to second lieutenant and traveled to Cambridge in England for officer training in October 1918.
He was wounded in November, within days of his return to the front. His service with the NZEF ended with his repatriation to New Zealand in 1919. Grant remained involved with military life, serving in the Territorial Force until 1929, by which time he had reached the rank of lieutenant.
He was discharged due to his age and also for being unable to attend camp.
He later worked in Paeroa, becoming noted for his erratic behaviour which meant he found it difficult to gain employment. Undiagnosed at the time, it is thought that Grant suffered from post-traumatic stress disorder.
Grant died at the age of 81, and is buried in Waikumete Cemetery in Auckland. On 2 December 2007 it was one of nine es that were among a hundred medals stolen from the museum.
On 16 February 2008, New Zealand Police announced all the medals had been recovered as a result of a New Zealand$300,000 reward offered by Michael Ashcroft and Tom Sturgess.
