In contrast to Tulagi, Gavutu, and Tanambogo, the landings on Guadalcanal encountered much less resistance. At 09:10 on 7 August, Vandegrift and 11,000 U.S. Marines came ashore on Guadalcanal between Koli Point and Lunga Point. Advancing towards Lunga Point, they encountered little resistance and secured the airfield by 16:00 on 8 August. The Japanese naval construction units and combat troops, under the command of Captain Kanae Monzen, panicked by the warship bombardment and aerial bombing, had abandoned the airfield area and fled about west to the Matanikau River and Point Cruz area, leaving behind food, supplies, intact construction equipment and vehicles, and 13 dead.
