History of the 113th antiaircraft artillery battalion. My grandfather wrote the history of battery D. He lost a toe to frostbite and hearing in 1 ear to German 88mm artillery shells in Belgium.

I think my father was there as well...Need to look up his records but he was AAA and most gunners were turned into Infantry because of a shortage of manpower.
