149 - Why did the Marines stop 1,000 yards short of victory at 4th Matanikau - Guadalcanal

After the defeat at Henderson Field, Japanese 17th Army headquarters remained confident — fresh divisions and hundreds of aircraft were promised within weeks. But Vandegrift had no intention of letting them regroup.
