Donation of World War 2 Japanese Flag

Published - 9 February, 2026

A Japanese flag signed by members of 2/2 Commando Squadron at the end of World War II has found its way to the SAS Historical Collection courtesy of the man who claimed to have stolen it, Edmund Bourke. 


The signaller served with the 2/2 in New Britain in 1945 and said he acquired the flag from an Imperial Japanese Navy ship after Japan’s surrender, according to his daughter Johanna Nesbitt.

“Dad told us that at the end of the war, when his unit were guarding the Japanese prisoners of war on their ships in Rabaul, he was dared by his mates to sneak onto their cruiser, the Kashima, and procure the ship’s flag from atop the flagpole,” Mrs Nesbitt told the 2/2 Commando Association memorial service in November.

“He took up the challenge, which he claimed couldn’t be any harder than the coconut picking he had been doing.  When he had shimmied to the top of the flagpole, in the process of releasing the flag, he was spotted by a Japanese soldier, and the alarm was raised.

“To escape, he dived from the pole into the waters below, with said flag tucked into his shorts.  It was reported that the ship’s commander was irate and demanded a beheading over the incident.  The Australian Army replied that they had investigated, and no culprit could be found.  Lucky for me!”

Mr Bourke’s family and the 2/2 Commando Association presented the flag to SAS Historical Foundation chair Greg Mawkes in January.

It will hang in SAS Regimental HQ at Campbell Barracks, a symbol of the respect today’s Special Forces owe the No. 2 Australian Independent Company (later 2/2 Commando Squadron) and its exemplary record in Timor and New Guinea during WWII.

Mr Bourke kept the flag in a Pond’s make-up jar for 40 years only to share it with his family late in life, and some doubt persists over its provenance.

“For many years we believed this to be the flag you now have in your charge, signed by members of the unit, Mrs Nesbitt said.

“However, the silk flag you have was not typical of the flags used on ships and there is another flag which probably fits this story more.

“This raises the question, where did this signed flag come from?  And how did it end up in Dad’s possession.  Sadly, the true story is lost forever but we can only assume that he was given it for safe keeping by the unit.”

Whatever the historical circumstances, Mrs Nesbitt said the flag held lasting significance for the story it told.

“So, whilst there is some confusion about the origin of the flag that you now have in your trust, it tells the story of the many men who courageously fought alongside each other in true Aussie mateship,” she said.
