770 Japanese troops under Colonel Kiyonao Ichiki reached within a few miles of Henderson Field at Guadalcanal, Solomon Islands by 0430 hours. During the day, Henderson Field received 31 US Marine fighter aircraft (19 Wildcat fighters and 12 Dauntless dive bombers) from USS Long Island, allowing air supply and evacuation of wounded to begin between Espiritu Santo and Guadalcanal; the small air fleet at Henderson Field was dubbed "Cactus Air Force". In the evening, Ichiki gave the order to move foward, running into the US Marines defensive perimeter at Tenaru River by surprise around midnight.
