On 7 December, one year after the Japanese attack on Pearl Harbor, General Vandegrift sent a message to all men under his command in the Guadalcanal area thanking them for their courage and steadfastness, commending particularly the pilots and "all who labored and sweated within the lines in all manner of prodigious and vital tasks." He reminded them all that their "unbelievable achievements had made 'Guadalcanal' a synonym for death and disaster in the language of our enemy." On 9 December, he handed over his command to General Patch and flew out to Australia at the same time the first elements of the 5th Marines were boarding ship. The 1st, 11th, and 7th Marines would soon follow together with all the division's supporting units. The men who were leaving were thin, tired, hollow-eyed, and apathetic; they were young men who had grown old in four months time. They left behind 681 dead in the island's cemetery.
The final regiment of the Americal Division, the 132d Infantry, landed on 8 December as the 5th Marines was preparing to leave. The 2d Marine Division's regiments already on the island, the 2d, 8th, and part of the 10th, knew that the 6th Marines was on its way to rejoin. It seemed to many of the men of the 2d Marines, who had landed on D-Day, 7 August, that they, too, should be leaving. These took slim comfort in the thought that they, by all rights, should be the first of the 2d to depart the island whenever that hoped-for day came.
General Patch received a steady stream of ground reinforcements and replacements in December. He was not ready yet to undertake a full-scale offensive until the 25th Division and the rest of the 2d Marine Division arrived, but he kept all frontline units active in combat and reconnaissance patrols, particularly toward the western flank.
The island commander's air defense capabilities also grew substantially. Cactus Air Force, organized into a fighter command and a strike (bomber) command, now operated from a newly redesignated Marine Corps Air Base. The Henderson Field complex included a new airstrip, Fighter Two, which replaced Fighter One, which had severe drainage problems. Brigadier General Louis Woods, who had taken over as senior aviator when Geiger returned to Espiritu Santo, was relieved on 26 December by Brigadier General Francis P. Mulcahy, Commanding General, 2d Marine Aircraft Wing. New fighter and bomber squadrons from both the 1st and 2d Wings sent their flight echelons forward on a regular basis. The Army added three fighter squadrons and a medium bomber squadron of B-26s. The Royal New Zealand Air Force flew in a reconnaissance squadron of Lockheed Hudsons. And the U.S. Navy sent forward a squadron of Consolidated PBY Catalina patrol planes which had a much needed night-flying capability.
