Arthur John DEWAR [1907-1967]
He's mentioned in the Hong Kong Volunteer & Ex-PoW Association of NSW's Occasional Paper No 8 Australians in Hong Kong in the Pacific War:
Captain Arthur John Dewar of the RASC was at the munitions depot, Little Hong Kong, on 27th December with some men refusing to surrender and threatening to blow up the depot. They were persuaded to surrender on promise of safe conduct. Dewar, from Swanbourne, West Australia, was awarded the DSO for distinguished service in the defence of Hong Kong.
