My dad ended up working in the Courts Martial office in germany after the 2nd war, around 1947. He had some tales to tell. One was of a british NCO who had spent the entire war in an army prison in Egypt because he'd been caught selling british army trucks to the arabs. On his release, he was reduced to the ranks and of course, still had to serve out his time. He sprang into action immediately selling british army petrol in a lay by on the german motorway. Apparantly, many soldiers saw british army stocks as private inventories to pilfer and flog off.
Dad got a bit worried though when he saw a file on his captain's desk with the name of the captain himself as the man to be investigated. Of course, investigating himself, he simply put a big red stamp on it, 'no further action required'. Dad did not look into what the supposed offence was.
His boss, the captain though interviewed many people during the post war years. One was a frenchman who had been in the french army when France surrendered. Of course, they were all out of a job and he had been a career soldier so when the germans started recruiting french soldiers to fight against the communists, he volunteered. In his mind, France had lost the war and this was now a different war. Having survived the eastern front, he found himself in the British sector and a british officer telling him that he couldn't go back to France. As a career soldier he didn't really understand why, he had afterall fought for his country and it wasn't his fault that France lost. He blamed those french that ran away to England for that, even though they weren't that many. But, the captain got this man a job with the french army in North Africa so he could spend 3 years there and then return to France in a french uniform again.
