Blood Is Thicker Than Water: Guadalcanal-October and the Japanese Offensive *1

FIRST OFFENSIVE: The Marine Campaign for Guadalcanal
by Henry I. Shaw, Jr.

On 30 September, unexpectedly, a B-17 carrying Admiral Nimitz made an emergency landing at Henderson Field. The CinCPac made the most of the opportunity. He visited the front lines, saw Edson's Ridge, and talked to a number of Marines. He reaffirmed to Vandegrift that his overriding mission was to hold the airfield. He promised all the support he could give and after awarding Navy Crosses to a number of Marines, including Vandegrift, left the next day visibly encouraged by what he had seen.

The next Marine move involved a punishing return to the Matanikau, this time with five infantry battalions and the Whaling group. Whaling commanded his men and the 3d Battalion, 2d Marines, in a thrust inland to clear the way for two battalions of the 7th Marines, the 1st and 2d, to drive through and hook toward the coast, hitting the Japanese holding along the Matanikau. Edson's 2d and 3d Battalions would attack across the river mouth. All the division's artillery was positioned to fire in support.


On the 7th, Whaling's force moved into the jungle about 2,000 yards upstream on the Matanikau, encountering Japanese troops that harassed his forward elements, but not in enough strength to stop the advance. He bypassed the enemy positions and dug in for the night. Behind him the 7th Marines followed suit, prepared to move through his lines, cross the river, and attack north toward the Japanese on the 8th. The 5th Marines' assault battalions moving toward the Matanikau on the 7th ran into Japanese in strength about 400 yards from the river. Unwittingly, the Marines had run into strong advance elements of the Japanese 4th Regiment, which had crossed the Matanikau in order to establish a base form which artillery could fire into the Marine perimeter. The fighting was intense and the 3d Battalion, 5th, could make little progress, although the 2d Battalion encountered slight opposition and won through to the river bank. It then turned north to hit the inland flank of the enemy troops. Vandegrift sent forward a company of raiders to reinforce the 5th, and it took a holding position on the right, towards the beach.
