ALEUTIAN ISLANDS: The USN lands 4,500 US troops to occupy Kuluk Bay, Adak Island, amidst a terrific storm and they start building a runway; this airfield, later named Davis AAFld. Adak Island is located about 219 nautical miles east of Japanese-held Kiska Island.
Five USAAF 11th Air Force B-24 Liberators photograph Kiska Island but do not bomb due to overcast, and then fly patrol and photo reconnaissance over Amchitka and Tanaga Islands. P-38 Lightnings fly patrol between Great Sitkin and Little Tanaga Islands. The occupation puts North Pacific forces within 250 miles of occupied Kiska and in a position to maintain a close watch over enemy shipping lanes to that and to Attu. The tender Casco, conducting support operations from Nazan Bay, was damaged by a submarine torpedo and temporarily beached.
AUSTRALIA: General Douglas MacArthur, Commander of the Southwest Pacific Area, sends a message to Washington stating ".... as I have previously reporated am not yet convinced of the efficiency of Australian units (at Milne Bay), Papua New Guinea and do not attempt to forecast results."
POA (7th AF): 6th Fighter Squadron, 18th Fighter Group, moves from Wheeler Field to Kahuku, Hawaii with P-40s.

BISMARCK ARCHIPELAGO: USAAF B-17 Flying Fortresses of the Allied Air Forces attack shipping in Saint George's Channel between New Ireland and New Britain Islands.
BURMA: Myitkyina, northernmost Japanese supply depot and airfield in Burma, from which fighters could hit Dinjan, India (terminus of the Assam-Burma Ferry), is bombed for the first time by eight China-based B-25s of the 10th Air Force's China Air Task Force.
NEW GUINEA: On the Kokoda Trail in Papua New Guinea, troops of the Australian 53d Battalion near Abuati are ordered to withdraw to Alola after being unable to get behind the Japanese troops. At 1500 hours local, the 39th Battalion is ordered to withdraw to Eora Creek, about 2 miles south of Alola. The officer commanding 39th Battalion, Lt Colonel Arthur Key, was later captured by the Japanese, interrogated and murdered. In Milne Bay, Australian troops continue patrolling and find several Australian dead with their hands tied behind them, arms broken by gunshot wounds and bayonetted.
SOLOMON ISLANDS: At 1400 hours local, 18 Zero fighters of the HIJMS Shokaku and HIJMS Zuikaku air groups, temporarily land based at Rabaul on New Britain Island, attack Allied targets. The Zero's outmaneuver 8 Marine Fighting Squadron VMF-223 F4F Wildcats and attack the high speed transport USS Colhoun wrecking the ship's boats and the after davits and starting a diesel fire from the boat wreckage.
The Zero's are then intercepted by USAAF P-400 Airacobras of the 67th Fighter Squadron, later joined by the VMF-223 Wildcats; the Americans shoot down five Zero's while losing four P-400s. Three F4Fs are written off when they land on Henderson Field, Guadalcanal leaving a total of five Wildcats to defend the island. After this action, the USAAF's P-400s are limited to medium-level interceptions and ground-attack missions. The evaluation of the P-400 by the Commander, Air South Pacific was, "No good at altitude and disheartening to the brave men who fly them." The 67th Fighter Squadron's
historian put it this way: "We can't maneuver and dogfight with the Zero -- what good are we? Our enlisted men are risking their lives every day trying to get the planes patched up -- for what? We're just eating up food -- and there's not enough to go around anyway, and using up valuable gasoline -- and the gas supply is getting lower every day. Hell, we can't fight. When the Japs come we're told to 'go on reconnaissance. ' What good are we?" In the ground attack role, the P-400 (P-39) will perform much better. The Japanese will give them the nickname of "Long Nosed Planes".
At 1517 hours local, 18 "Betty" bombers make an unopposed attack on USS Calhoun scoring a succession of hits on the starboard side which brought down the foremast, blew two 20 mm guns and one 4-inch (10.1 centimeter gun off the ship, and damage the engineering spaces. Two more direct hits kill all the men in the after deck house. Tank lighters from Guadalcanal rescued the crew, and Calhoun sinks about 2.2 nautical miles WNW of Henderson Field on Guadalcanal in position 09.24S,
160.01E with the loss of 51 men and 18 wounded. Shortly after 1500 hours, shortly before the "Betty" bomber attack, the first sizable aerial reinforcements arrive at Henderson Field in the form of 19 F4F-4's of VMF-224 and 12 SBD-3's of Marine Scout Bombing Squadr VMSB-231). At days end, the Cactus Air Force on Guadalcanal consisted of 86 pilots and 64 aircraft (including three USAAF P-400s and ten USN SBDs).
