This military campaign aimed at attacking and isolating Japanese bases located in different islandS in the Pacific. One of these was Iwo Jima that is a Japanese volcano island, this island was key in this operation because by taking this island the Allies could control the three Japanse airfields located in Iwo Jima and from these attack major islands.
