Letters from Iwo Jima (2006)

In 2005, Japanese archaeologists explore tunnels on Iwo Jima, where they find something in the dirt. The scene changes to Iwo Jima in 1944. Private First Class Saigo and his platoon are digging beach trenches on the island. Meanwhile, Lieutenant General Tadamichi Kuribayashi arrives to take command of the garrison and immediately begins an inspection of the island defenses. He saves Saigo and his friend Kashiwara from a beating by Captain Tanida for ‘unpatriotic speeches’, and orders the men to begin tunneling underground defenses into Mount Suribachi. Kuribayashi and Lieutenant Colonel Baron Takeichi Nishi, a famous Olympic gold medalist show jumper, clash with some of the other officers, who do not agree with Kuribayashi’s defense in depth strategy: Kuribayashi believes the US will take the beaches quickly, and that the mountain defenses will have a better chance for holding out.

Poor nutrition and unsanitary conditions take their toll; many die of dysentery, including Kashiwara. The troops begin using the caves. Kashiwara’s replacement, Superior Private Shimizu, arrives for duty. Saigo suspects that Shimizu is a spy from the Kempeitai sent to report on disloyal soldiers. 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.
