I think that must have been Loza's memoir. It's a bit limited in scope since it's a memoir and all, but still worth a read. The only other work that goes into any depth on the topic is my book that I will shamelessly promote ;)
I wrote a book about this very topic: https://www.amazon.com/Sherman-Tanks-Red-Army-American/dp/1911658476/
