Information has been received by Mrs. A. G. Thomas, of Broken Hill, that her son, Corporal S. C. Mountain, died on board a transport on August 23, the cause of death being broncho pneumonia. Corporal Mountain joined the colors in January last. He quickly rose to the rank of sergeant, but owing to a brief illness was reduced to corporal and stayed with that rank. He was educated at St Peter's College. In civil life he was employed as electrician on the "line of lode." He was 23 years of age." - from the Adelaide Advertiser 03 Oct 1916 (



From the book Fallen Saints  -  Sydney Chalmers Mountain was born at Broken Hill South, New South Wales and educated at Broken Hill Central School and the Collegiate School of Saint Peter. He completed a 5-year apprenticeship as an electrician at Broken Hill and when he enlisted in Adelaide on 14 January 1916 was working as a Motor Mechanic.

Later in the month, he was posted to E Company 2nd Depot Battalion at Exhibition AIF Camp promoted to acting corporal at the start of February.

He attended an NCO course at Mitcham Camp 1 April -15 May and was posted to A Company as a provisional sergeant but when reallotted to the 4th quota of reinforcements for the 48th Battalion in June; he was reverted to provisional corporal in July.
