At 1100 hours, Coast Watchers reported incoming Japanese aircraft flying south from the Lae, New Guinea area. Shortly after, 8 Japanese Type 1 bombers and 11 Zero fighters attacked Port Moresby, Australian Papua. In the ensuing combat, two of the Kittyhawk fighters attempted to engage in dogfights with Zero fighters at a high altitude, which caused their engines to stall, leading to the two fighters' crash. After the attack, Port Moresby personnel discovered one of the Japanese bombers had delivered a bag containing 395 letters written by prisoners of war kept in Rabaul, New Britain; actually two khaki bags of mail were dropped, but one of them fell in the water.
