history has the amphibious assault of stalingrad? :P
No amphibious, but infact there were some troop landings on a bank of the Volga River in some part of the town. Nothing realy important though.
Actually, *ahem*, *cough*, the Volga river boats were one of the main reasons the Soviets were able to hang on. You'll note that they never actually lost a foothold on the West bank of the river, but large numbers of barges, civilian craft, gunboats, and anything else that would float constantly ferried reinforcements across, in order to allow Chuikov to hang on.
Nothing as dramatic as an amphibious assault (although I wouldn't doubt that some landings under fire took place in yet-unoccupied sectors), but the shipments of terrified recruits under fire and air attack that you see creatively represented in CoD (I think that's the one?) did take place, especially given that the Germans reached the Volga during November--the Soviets only maintained two small pockets on the West bank.
Call of Duty borrowed that scene from Enemy at the Gate film.:)
