The American invasion, designated Operation Detachment, had the goal of capturing the entire island, including the three Japanese - controlled airfields (including the South Field and the Central Field), to provide a staging area for attacks on the Japanese main islands . This five - week battle comprised some of the fiercest and bloodiest fighting of the Pacific War of World War II . </P> <P> After the heavy losses incurred in the battle, the strategic value of the island became controversial . It was useless to the U.S. Army as a staging base and useless to the U.S. Navy as a fleet base . However, Navy Seabees rebuilt the landing strips, which were used as emergency landing strips for USAAF B - 29s . </P>
