“Saipan combined everything that the Americans had learned to hate about fighting the Japanese,” wrote historian Brian Blodgett in his paper “The Invasion of Saipan.” “The island was comprised of varied landmasses with swamps, sugarcane fields, jungle-covered mountains, and steep ravines.”Peering through his binoculars, Vice Adm. Chuichi Nagumo was in awe of the nearly 800 ships from Vice Adm. Raymond A. Spruance’s 5th Fleet. Just three years before he had led the carrier force at the surprise attack on Pearl Harbor that initiated hostilities between Japan and the United States. But this was no time to gloat over past victories. As he lowered his glasses, Nagumo realized that the Americans must be stopped here. If the invading forces captured Saipan, their Boeing B-29 Superfortress bombers could easily reach Japan itself.Saipan, about 85 square miles in size, is the southernmost island in the Marianas chain. It was the next important step in the Allied planning to conquer Japan. One of Saipan’s dominating features is Mount Tapotchau, over 1,500 feet high, situated near the center of the island. Also, a ridge runs from the southern end all the way to Mount Marpi at the extreme northern tip. To make things worse, steep cliffs dominate the region and a plateau is located in the southern area.(Originally Published May 29, 2019.
