I asked this before but I didn't get an answer; My grandfather was in the army during ww2 and I was too young (7/8) to really know what he did during the war before he died and my mum doesn’t know either, just that he was deployed in Italy. Recently whilst going through some of his things we found a photo album with some of his things from that time and a lot of them have “Casarsa” 1947 written on it so I was wondering if it was relevant to his time in the war. He was in the RAF, DLI and RAOL as far as I can tell if that’s relevant.
British troops were deployed to north east Italy post-war, one of the primary reasons being the city of Trieste, on the border of Italy and Yugoslavia, and subject to competing claims. As a potential Cold War flashpoint, the Free Territory of Trieste was established in 1947, administered by British, American and Yugoslav forces, the British contributing BETFOR - British Element Trieste Force. There's some more information at the Free Territory of Triests site, including documents from the National Archives.
There's one reference to Casarsa in an account submitted to the BBC People's War project, Italy, Occupation Duties near the Yugoslav Border: "The troop got another job, that of security at a large vehicle park, near Casarsa. As jeeps, trucks and heavies were no longer required they were stored here in the open. The park was protected by a fence and barbed wire. We installed a telephone system around the perimeter and organised an exchange HQ."
If you'd like more information about your grandfather's service you might find the Guide to Requesting Military Records useful, it should be possible to get his records from the government.
