Henry’s birth to John and Mary Weick was registered at Warialda in 1891. When he enlisted at Warialda in January 1916 he stated he was a twenty three year old Mail Driver and agreed to allocate three shillings of his army pay to his Mother. Henry, with ten other district men, joined Inverell’s Second Contingent of Kurrajongs at Kelly’s Gully Railway station on their way to the Narrabri Camp.
He became a member of the 33rd Battalion, 5th Reinforcement and sailed from Australia on the SS Port Napier in November 1916. After arriving in England at the end of January 1917 he was eventually sent to France in April. During the Battle of Messines in June he was gassed and required some medical treatment. After returning to his unit he was wounded again in October and invalided back to England where he was admitted to 3rd Southern General hospital in Oxford with a gunshot wound to his leg.
Henry returned to Australia in February 1919 and was medically discharged in March. His name is recorded on the Warialda Honour Roll.
