On July 26 1942, the 1st Marine Division is sailing towards Guadalcanal. On August 7, the Marines land on Guadalcanal with no initial opposition. They find an abandoned village and capture an airfield, which the Americans work to complete, and rename it Henderson Field. Based on a tip from a Japanese deserter, the Marines leave by boat for the village of Matanikau, where there are supposedly a large number of Japanese troops who want to surrender. On the way, one boat is destroyed by a Japanese submarine before it is sunk by onshore Marine artillery.
