Why did you say Burma?
My grandmother had a hospital in France in WW1 and was a surgeon. Among her belongings I found a book detailing treatments of battlefield injuries. Primarily shrapnel IIRC. Unfortunately, I can’t refer to it because I gave it to a Combat Medic on his way to Afghanistan.
Britain contributed to the Pacific War not only through Australia but also by supplying Chiang Kai Shek’s forces via the Stilwell Road and by supplying air bases in Assam for mostly American transport aircraft to fly over “the Hump” from Assam to China.
In Burma the Fourteenth Army defeated the Japanese Army comprehensively in the 1945 campaign, despite being deprived of equipment for the needs of the European theatre.
