On 14 May 1915 the Westralian Worker reported on
Private Amos, of the 11th Battalion, who died of wounds received at the Dardanelles. He was, so far as is known, the first soccerite from W.A. to pass the bourne from whence no traveller returns. At one time he played for Y.M.C.A. and later went in for refereeing. He was a good lad, only 24 years of age, and unmarried. All honor to his memory.”
The following week the The Daily News also reported on his death:
Private Harry Oswald Amos, killed at the Dardanelles was 24 years of ago, and prior to his enlistment was employed by Messrs. G. and R. Wills and Co. He was a Welshman by birth, and was a prominent member of the Y.M.C.A., where he took a great interest in Association football. Private Amos was first of all attached to the 11th Battalion, but was subsequently transferred to the 16th, He was very popular, especially in the Y.M.C.A., and the announcement of his death came as a great shock to a large circle of friends.
Private Amos received a penetrating wound to the abdomen during the Anzac landing on 25 April 1915 and died at sea a few days later on board the HMT Seang Choo.
