Receiving intelligence that enemy ships were massing again to the northwest, General Patch took steps, as Vandegrift had before him on many occasions, to guard against overextending his forces in the face of what appeared to be another enemy attempt at reinforcement. He pulled the 25th Division back to bolster the main perimeter defenses and ordered the CAM division to continue its attack. When the Marines and soldiers moved out on 26 January, they had a surprisingly easy time of it, gaining 1,000 yards the first day and 2,000 the following day. The Japanese were still contesting every attack, but not in strength.
By 30 January, the sole frontline unit in the American advance was the 147th Infantry; the 6th Marines held positions to its left rear.
The Japanese destroyer transports made their first run to the island on the night of 1-2 February, taking out 2,300 men from evacuation positions near Cape Esperance. On the night of 4-5 February, they returned and took out most of the _Sendai_ survivors and General Hyakutake and his _Seventeenth Army_ staff. The final evacuation operation was carried out on the night of 7-8 February, when a 3,000-man rear guard was embarked. In all, the Japanese withdrew about 11,000 men in those three nights and evacuated about 13,000 soldiers from Guadalcanal overall. The Americans would meet many of these men again in later battles, but not the 600 evacuees who died, too worn and sick to survive their rescue.
On 9 February, American soldiers advancing from east and west met at Tenaro village on Cape Esperance. The only Marine ground unit still in action was the 3d Battalion, 10th Marines, supporting the advance. General Patch could happily report the “complete and total defeat of Japanese forces on Guadalcanal.” No organized Japanese units remained.
On 31 January, the 2d Marines and the 1st Battalion, 8th Marines, boarded ship to leave Guadalcanal. As was true with the 1st Marine Division, some of these men were so debilitated by malaria they had to be carried on board. All of them struck observers again as young men grown old “with their skins cracked and furrowed and wrinkled.” On 9 February, the rest of the 8th Marines and a good part of the division supporting units boarded transports. The 6th Marines, thankfully only six weeks on the island, left on the 19th. All were headed for Wellington, New Zealand, the 2d Marines for the first time. Left behind on the island as a legacy of the 2d Marine Division were 263 dead.
