 The general idea of an LSTH would be to bring troops to shore, but the convenience of a ship beached ashore proved to be an inviting harbor for the sick and injured, who could simply walk aboard.On D-Day most of the troops were not landed by LSTs, however 41,035 wounded were brought back on approximately 150 LSTs, which was twice their troop capacity.The sheer numbers overwhelmed the modest sick bay facilities on these craft which were staffed by one or two Pharmacist Mates.
