Battle of Edson’s Ridge, Guadalcanal. Japanese again underestimate US strength (12,500 troops), as General Kawaguchi believes there are only 2000 Marines on Guadalcanal. Kawaguchi has 6200 men approaching the US perimeter from East, South and West. Japanese bombers again attack Lunga Ridge during the day. Japanese cruiser Sendai and three destroyers shell Henderson Field and the Ridge for 20 minutes at 9.30 PM. Japanese troops are late arriving at the starting point (due to a lengthy trek through dense jungle) and attack up the slope overnight, overrunning some US positions in confused fighting but generally making little progress.
