He had served three years with the 5th Australian Light Horse before enlisting at Narrabri NSW in July 1916. At this time he was a thirty nine year old Grazier, married and living at Bywanna, Boomi.

After arriving in England in January 1917 his Battalion had further training until sent to France in April as part of the 3rd Division commanded by General Monash. Just two months later he was wounded in action and treated for shell shock. He did not rejoin his unit until September. The following month Herbert was promoted to Corporal.
