Bob Bolton, Many thanks for all your efforts. It looks as if there could have been quite a lot of 'folklore' in circulation about Kokoda after the men came back but for reasons best known to the authorities and media of the day it was not given 'front page' treatment.
I didn't get here until the 'sixties and although I've always been interested in history I've never come across any detailed accounts of the campaign in books or films or on tv. Maybe the fact that Japan is our biggest trading partner had something to do with it.
