He was 29 years old, and a lieutenant in the 5th Victorian Mounted Rifles when the following deed took place for which he was awarded the Victoria Cross:
On 23 November 1901 at Geelhoutboom, Natal, Maygar galloped out and ordered men of a detached post, which was being outflanked, to retire. The horse of one of the men was shot under him when the enemy were within 200 yards and he dismounted and lifted the man on to his own horse which bolted into boggy ground, making them both dismount. As the horse could not carry two, Maygar again put the man on its back and told him to gallop for cover at once, while he himself went on foot. All this took place under very heavy fire.
Maygar's award was presented by Lord Kitchener and he was later also mentioned in despatches. He returned to Australia in March 1902.
