Morning attack At approximately 9:00 AM, carrier planes from the
USS Enterprise operating under
William Halsey Jr. attacked neutral
Macau. U.S. authorities were reportedly aware of Portuguese intentions to sell part of their aircraft fuel stock to the Japanese, which prompted the operation. The first group, led by Lt. Kemper, encountered no opposing aircraft and attacked the seaplane hangar before proceeding toward
Sha Chau. Twenty minutes later, the second group arrived and set the hangar ablaze. At 9:30 AM, Lt. Kemper returned to inspect the target. He concluded that it had been destroyed and the groups of Hellcats then withdrew toward the fleet. , who was 21 years old at the time and serving in the military, notes in his book
Memórias do Oriente em Guerra: According to his account, the planes flew low over the city center, heading towards the Naval Aviation Center, where they dropped some bombs and fired machine shots. The attacked hangar stored a large amount of fuel that was to be delivered to the Japanese in exchange for rice. The strike also hit the old prewar Pan Am hangar and a power station. The
Fort Dona Maria II was bombed and sustained damage, and the former Maritime Museum of Macau, then housed in the aviation hangar, was destroyed. Casualties range from five deaths to two soldiers and several civilians killed. During the raid, Commander Álvaro Salgado mobilized personnel to the sandbag fortifications. Two of the aircraft attacked the military barracks, damaging windows and plumbing and causing injuries among the stationed soldiers. The morning attack ended around 11:45 AM.
Afternoon attack Later between 3:00 and 3:30 PM, four aircraft under Lt. E. W. Niebling returned over Macau.
Pedro José Lobo and his son Rogerio, who were surveying the damage to the hangar, heard approaching aircraft and took cover as Niebling and his wingman opened fire. Heavy machine-gun rounds riddled the hangar but both survived without injuries.
Consequences The raid shocked the locals of Macau and drew protests from the
Portuguese government, which denounced it as a violation of Portugal's neutrality. On 20 January,
Washington issued an apology for what it described as an "error" and offered financial compensation. Although Lisbon accepted the apology, resentment persisted as the Inner Harbour was subjected to subsequent bombing raids. ==25 February raid==
