In November 1943, the men of the 2d Marine Division were instructed to clear out Japanese resistance on the Pacific island of Betio, a speck at the end of the Tarawa Atoll. When the Marines landed, the Japanese poured out of their underground bunkers—and launched one of the most brutal and bloody battles of World War II. For three straight days, attackers and defenders fought over every square inch of sand in a battle with no defined frontlines, and where there was no possibility of retreat—because there was nowhere to retreat to. It was a struggle that would leave both sides stunned and exhausted, and prove both the fighting mettle of the Americans and the fanatical devotion of the Japanese. Drawn from new sources, including participants’ letters and diaries and exclusive firsthand interviews with survivors, is the true story of a battle between two determined foes, neither of whom would ever look at the other in the same way again.
