Col. Edson issued his attack orders for D+1 at 04:00 hours. 1/8, attached to 2nd Marines was to attack at daylight to the west along north beach to eliminate Japanese pockets of resistance between Beaches Red 1 and 2. On Red Beach Two, Major Hays launched his attack promptly at 07:00, attacking westward on a three-company front. Engineers with satchel charges and bangalore torpedoes helped neutralize several inland Japanese positions, but the strongpoints along the re-entrant were still dangerous. Marine light tanks made frontal attacks against the fortifications, even firing their 37mm guns point blank into the embrasures, but they were inadequate for the task. One was lost to enemy fire, and the other two were withdrawn.
