HIS Helensburgh neighbours call him Arthur but to his old comrades he was Crazy Kennedy - the one with the dents in his forehead who didn't seem fazed by flying bullets or advancing Japanese artillery.Arthur Kennedy was a gunner for the Australian Imperial Force when Singapore was taken by the Japanese in February 1942.He watched Japanese soldiers land at dawn and endured a barrage of shells for five days before the British High Command surrendered and he was made a prisoner of war.Mr Kennedy has recounted his experience for an SBS documentary timed to coincide with the 70th anniversary of the fall of Singapore.The day the Japanese landed, he watched them "walk straight through" the Australian infantry."Every time you turned a light on there was a hail of bullets - it was fun and games for everybody," said Mr Kennedy, 94.When the order came to stand down, he accidentally drove his artillery tractor into a 180cm-deep ditch, then stayed behind to sabotage it because "it was my gun - there was no way the Japanese were going to fire it."The gun was propelled by cordite and went up with a great flare, temporarily blinding the then Lance-Bombardier Kennedy."I couldn't see. I knew that the drain was beside me and if I got in it I only had to follow it, so I walked along that for a couple of hundred yards," he said."I came on this fellow; he looked Japanese but he turned out to be Chinese. They armed themselves to fight the Japanese."At no time was I scared. That's why they call me Crazy Kennedy."Mr Kennedy suffered lasting scars in his forehead in Gemas, Malaya, a month before Singapore fell, when he volunteered to run a message to a superior as gunfire sounded all around. He doesn't know what debris hit him and caused the marks.He was nominated for a military medal for returning that day to bogged guns and setting off three rounds at enemy machine guns about 180m away.However, he did not receive the medal and was recently told the paperwork was never completed.Part one of Singapore 1942 - End of Empire, screens on Friday at 8.30pm.
