in 1944, during Operation Flintlock, from the 4th Marine Division captured Roi and Namur, part of the Marshall Islands in the Northwest Pacific Ocean.
On Jan. 31 around 03:00, 42 Marines from the V Amphibious Corps Reconnaissance Company landed aboard Roi and Namur from rubber boats to secure the small island strip that connected the islands. Securing the strip effectively halted all Japanese movement between the two islands.
Around noon on Feb. 1, the Marines and U.S. Army soldiers commenced a multi-prong amphibious assault on the islands. The Marines quickly and decisively captured the island of Roi; however, Namur had a substantially larger enemy presence, as well as containing more structures and denser vegetation.
American forces dug in for the night of Feb. 1 to regroup and reorganize. At dawn, a company-sized enemy element engaged the Marines in hand-to-hand combat, which the Marines handily won.
The final assault on Namur commenced on February 2. The combined arms assault was incredibly effective, being spearheaded by tanks and half-tracks and supported by infantry. Within 6 hours, the commanding general of 4th MARDIV declared the island secure.
In 60 hours of fighting, 3,472 enemy combatants were killed at a cost of only 190 Marines.
During the battle, 4th Marine Division became the first American division to use rockets mounted on jeeps, trucks, and gunboats in combat.
This decisive victory is credited in part to the lessons learned during the harrowing Battle of Tarawa, including the need to use naval gunfire as a means of both destroy enemy positions prior to landing and neutralize enemy firing positions during the assault.
