My father was in HQ Company of the 159th (Welsh) Field Ambulance from 1940 to 1944 including Dunkirk, North Africa (Operation Torch), Sicily (Operation Husky) and Southern Italy. In the book Battleaxe Division History of the 78th Division 1942-5, by Ken Ford it lists the RAMC in the Order of Battle as including the 11th, 152nd and 217th Field Ambulances. I wonder if this is a typographical error and they meant the 159th rather than 152nd? I haven't confirmed where the 152nd were in 1943 but they were attached for much of the war to the 51st Highland Division which makes me think this may be an error? Any help gratefully accepted about this period or especially the retreat to Dunkirk in 1940.
