The Mariana and Palau Islands Campaign was a significant military operation during World War II, taking place from June to November 1944. The campaign aimed to capture strategic islands in the Mariana Islands, including Saipan, Guam, and Tinian, to establish air bases for the Allied forces. This would enable long-range bombing missions against Japan. The campaign also included the invasion of the Palau Islands, particularly Peleliu and Angaur. These islands were crucial for securing supply routes and providing support for future operations in the Pacific. The campaign marked a turning point in the war, leading to increased Allied control in the region.
