A lot of marines on Tarawa got shot up because of someone's stupid mistake. They were supposed to go in at high tide as sand bars were a big problem at low tide. Someone misread the tide tables and sent them in at low tide. The boats were getting hung up on sandbars and were sitting ducks for the Japs mortars.
