Soon, American aircraft and warships begin to appear and bombard the island, causing significant casualties. A few days later, the U.S. Marines land. The American troops suffer heavy casualties, but the beach defenses are quickly overcome, as Kuribayashi predicted, and the attack turns to the positions on Mount Suribachi. While delivering a request for more machine guns from his commander to the Suribachi garrison, Saigo overhears Kuribayashi radioing orders to retreat. The commander, however, ignores the General and instead orders his company to commit suicide. Saigo runs away with Shimizu, convincing him to continue the fight rather than die. They find two other soldiers, but one is incinerated by an American flamethrower, and they witness a captured Marine being bayoneted to death.
