THEY played together in an undefeated season, and for five of Port Adelaide's 1914 premiership and Champions of Australia team, the battlefield of football would shortly transform into one of war.

Joseph Watson, Roy Drummond, William Boon, Albert Chaplin and John Robertson would all enlist to serve in the Australian Imperial Forces in The Great War following their unbeaten - and unmatched - 1914 football campaign.

Locals of the Port district - four of them living in the famous streets surrounding Alberton Oval -  the quintet would fight primarily in the north of France on the Western Front against the Central Powers. 

They were part of a 22-strong contingent of former Port Adelaide players to have joined the campaign.

Drummond, as discovered earlier this year,would become Port Adelaide's first Military Medallist for bravery in the field.

Robertson would serve as a gunner with the 8th Field Artillery Brigade.

Chaplin would be the first Port Adelaide soldier to be killed in action in 1916, Boon in 1918, while Watson would die from battle wounds in 1917.

Theirs are stories shared by thousands of other Australians to have fought in numerous armed conflicts since the First World War and reflected on by citizens of the Allied states on today's 96th anniversary of its Armistice.

The Port Adelaide Football Club continues to expand its list of player and official servicemen to have served in Australia's armed forces since 1914, ahead of next year's 100-year commemoration of the Australia and New Zealand Army Corps, with its current focus on completing a list of 'League' soldiers.

The club will host Hawthorn at the Adelaide Oval on ANZAC Day 2015.

Among almost 100 known servicemen are the eleven known League footballers to have died in armed conflict. They include:
