Did this man die at Bullecourt?

Why did George Abbott enlist in 1915, and then desert?  Why did he rejoin the army under another name, George T Connors, and desert again?

Rod Martin asks these questions and more in his new article "Private George Abbott - the man who wasn't there?"

When George Connors was released from a one month prison sentence in August 1916, the MPs picked him up as George Abbott and returned him to training. 

Who was he really?
