Essentially, the Japanese who broke out of the encircling Americans escaped from the frying pan only to fall into the fire. Admiral Turner finally had been able to effect one of his several schemes for alternative landings and beachheads, all of which General Vandegrift vehemently opposed. At Aola Bay, 40 miles east of the main perimeter, the Navy put an airfield construction and defense force ashore on 4 November. Then, while the Japanese were still battling the Marines near Tetere, Vandegrift was able to persuade Turner to detach part of this landing force, the 2d Raider Battalion, to sweep west, to discover and destroy any enemy forces it encountered.
Lieutenant Colonel Evans F. Carlson’s raider battalion already had seen action before it reached Guadalcanal. Two companies had reinforced the defenders of Midway Island when the Japanese attacked there in June. The rest of the battalion had landed from submarines on Makin Island in the Gilberts on 17-18 August, destroying the garrison there. For his part in the fighting on Makin, Sergeant Clyde Thomason had been awarded a Medal of Honor posthumously, the first Marine enlisted man to receive his country’s highest award in World War II.
In its march from Aola Bay, the 2d Raider Battalion encountered the Japanese who were attempting to retreat to the west. On 12 November, the raiders beat off attacks by two enemy companies and then relentlessly pursued the Japanese, fighting a series of small actions over the next five days before they contacted the main Japanese body. From 17 November to 4 December, when the raiders finally came down out of the jungled ridges into the perimeter, Carlson’s men harried the retreating enemy. They killed nearly 500 Japanese. Their own losses were 16 killed and 18 wounded.
The Aola Bay venture, which had provided the 2d Raider Battalion a starting point for its month-long jungle campaign, proved a bust. The site chosen for a new airfield was unsuitable, too wet and unstable, and the whole force moved to Koli Point in early December, where another airfield eventually was constructed.
The buildup on Guadalcanal continued, by both sides. On 11 November, guarded by a cruiser-destroyer covering force, a convoy ran in carrying the 182d Infantry, another regiment of the Americal Division. The ships were pounded by enemy bombers and three transports were hit, but the men landed. General Vandegrift needed the new men badly. His veterans were truly ready for replacement; more than a thousand new cases of malaria and related diseases were reported each week. The Japanese who had been on the island any length of time were no better off; they were, in fact, in worse shape. Medical supplies and rations were in short supply. The whole thrust of the Japanese reinforcement effort continued to be to get troops and combat equipment ashore. The idea prevailed in Tokyo, despite all evidence to the contrary, that one overwhelming coordinated assault would crush the American resistance. The enemy drive to take Port Moresby on New Guinea was put on hold to concentrate all efforts on driving the Americans off of Guadalcanal.
