Harold John Gordon (SN 3779) was born in Ballarat and was working as a hospital attendant at the time of his enlistment in Melbourne on July 10th 1915. He left Melbourne with the 8th Battalion on board the Ceramic in November. In Egypt he was transferred to the 14th Battalion and posted to France in June 1916. He was wounded in action at Passchendaele in June 1917, suffering gunshot wounds to his right hand and left foot which were serious enough to see him evacuated to England. He left England, bound for home, on board the Runic in December 1917 and was discharged on August 23rd 1918.

Harold re-enlisted for home service just a few weeks later, on September 12th 1918 (SN 80084) and served as a hospital porter at the AAMC Military Sanatorium in Macleod until he was discharged at his own request on January 8th 1919. He enlisted a third time on September 16th 1919 (SN 83043), once more serving at the Macleod Military Sanatorium. He was discharged for the last time at his own request on March 24th 1920.

Two of his brothers also served in the AIF and are honoured with adjacent trees in the Avenue. James was killed at Fromelles in 1916 and Charles served in France, returning home in 1918. His brother in law Samuel Davey also served in the AIF and is honoured with a tree in the Avenue.
