Henry Jesse Trimmer Brown (SN 526) enlisted in Footscray on August 17th 1914. At that time he was a 19 year old clerk from Havelock Street in Ballarat. Enlisting as a Sergeant, probably based on his Cadet service record, he embarked from Melbourne with the 7th Battalion aboard the Hororata on October 19th and took part in the Gallipoli landing on April 25th 1915. As a consequence of the loss of so many officers in the fighting and confusion of the first few days at Anzac, he was promoted to 2nd Lieutenant on April 28th.

Late in the afternoon of May 8th, the 7th Battalion was ordered to advance against the entrenched Turks over open ground and without artillery support. Pressing on under increasingly heavy enemy small arms and artillery fire, their losses eventually forced the Australians to a standstill. The hour-long advance had cost the 2nd Brigade 1,000 casualties, or one third of its strength. During that advance Lieutenant Brown was wounded twice, one bullet entering his left foot and another smashing into his right forearm. He was evacuated to Malta but rejoined his battalion in Egypt in December after the Gallipoli evacuation and, in March 1916, he moved on to France. On July 1st he was promoted to Lieutenant but on July 25th 1916, when still just 21 years old, he was killed in action at Pozieres. His record notes he was buried near the trenches by men of the 17th Battalion but his grave could never be located and he is commemorated on the Australian National Memorial at Villers-Bretonneux in France.
