Carlson's raiders come ashore at Aola Bay on November 4, 1942.
On November 5, Vandegrift ordered Carlson to take his raiders, march overland from Aola, and attack any of Shoji's forces that had escaped from Koli Point. With the rest of the companies from his battalion, which arrived a few days later, Carlson and his troops set off on a 29-day patrol from Aola to the Lunga perimeter. During the patrol, the raiders fought several battles with Shoji's retreating forces, killing almost 500 of them, while suffering 16 killed themselves. In addition to the losses sustained from attacks by Carlson's raiders, tropical diseases and a lack of food felled many more of Shoji's men. By the time Shoji's forces reached the Lunga River in mid-November, about halfway to the Matanikau, only 1,300 men remained with the main body. When Shoji reached the 17th Army positions west of the Matanikau, only 700 to 800 survivors were still with him. Most of the survivors from Shoji's force joined other Japanese units defending the Mount Austen and upper Matanikau River area.
