Fremantle is a port city near Perth and is where all Western Australian Gallipoli ANZAC troops departed for war. World War I was declared on 5th August 1914 and the first troops went to Blackboy Hill (in Greenmount, outside Perth) to train twelve days later on 17th August 1914. Blackboy Hill was used as a training base by over 32,000 Australians between 1914 and 1918. The first troops from Blackboy Hill caught a train from Blackboy Hill to Fremantle to board the boats on 31st October 1914, before departing for World War I.
Even though Albany is remembered as being the place where all the troops left for war, only men from other states departed from Albany. Most of the men from Western Australia and some troops from South Australia left from Fremantle.
On the 2nd November 1914 two ships left from Victoria Quay, just near where the Maritime Museum now stands. The two boats were the HMAT Ascanius (carrying Western Australia's 11th Infantry Battalion and South Australia's 10th Infantry Battalion) and the HMAT Medic, carrying WA's 12th Infantry Battalion, WA's 3rd Field Company Engineers, SA's 8th Battery 3rd Field Artillery Brigade and the Divisional Train. The HMAT Ascanius (below, leaving Fremantle) was the first ship to leave the area that carried troops.
