Being a creature of history I know the failings of logistics and their effect on war. My question is did the Allied effort to supply some of their various invasions ever come close to failing just because of shear volume of needed supplies? Not through enemy action like the Battle for the Atlantic but just because of lack of cargo vessels? In WWII did a supply line made up of ships ever come close to failing not because of enemy action but by shear volume of supply required? I read constantly about how this or that offensive or attack stalled because of lack of supply. Was it ever due to lack of shipping alone?
