Despite George Kenney's orders for an all-out attack on Rabaul, New Britain at dawn, Kenneth Walker launched a limited (without 63rd Bomb Squadron, whose commander William Benn disagreed with the timing of the attack) mid-day attack. Bad weather in Australia prevented some of the B-24 bombers from launching, thus ultimately only 6 B-24 bombers and 6 B-17 bombers took off for the attack. Two B-17 bombers attacked Lakunai and Vunakanau airfields near Rabaul between 0900 and 0930 hours. At 1200 hours, 6 B-24 bombers and 3 B-17 bombers (one of which carried Walker) attacked, sinking army transport Keifuku Maru, damaging two merchant ships, and damaging destroyer Tachikaze; 3 Ki-43 fighters were shot down during the raid. At 1317 hours, B-17 bomber San Antonio Rose was shot down; Walker and the entire crew were reported as missing, and none of them would be found.
