Allied missions against Kapingamarangi (Greenwich)
December 15, 1941–March 9, 1944

December 15, 1941
(RAAF) Hudson piloted by F/Lt Erwin from No. 24 Squadron made a photographic reconnaissance flight over Kapingamarangi about 300 miles north of Rabaul. A merchant ship between 4,000 and 5,000 tons which put to sea as the Hudson flew over and which opened fire with light anti-aircraft guns without causing damage. This was the only vessel of size sighted. There were 19 barges, two lighters and a launch lying off shore and the enemy had built two slipways on the beach. The merchant ship appeared to be making its best speed on a northerly course. An obvious target for attack, it was selected for the first combat strike in the area. Later that day, a flight of three Hudsons from No. 24 Squadron piloted by Erwin, F/Lt Murphy and Paterson found the ship 20 miles to the north of Kapingamarangi and bombed it without obtaining a direct hit; one 'near miss' was observed. The ship replied with light and ineffectual anti-aircraft fire. When northern area HQ received the report of this operation, the reaction was sharply critical. A letter to the whole squadron on the 17th complained that the whole operation had been wasted effort and described the bombing attack as "lamentable".

(USN) PB4Y 31992 pilot LtCdr Bruce A. Van Voorhis performs a lone reconnaissance over Kapingamarangi to report enemy movements. Over the target, the bomber came under anti-aircraft fire and aerial opposition. Van Voorhis made six ground attacks on the base, hitting radio station, and claimed one plane in the air shot down, and three destroyed in the water. Likely caught by its own bomb blast or accurate anti-aircraft fire, it crashed into the lagoon only 700 meters from the base, near the beach area it was attacking. Everyone aboard was killed in the crash and listed as Missing In Action (MIA). For his actions, Van Voorhis earned the Medal of Honor, the only navy PB4Y-1 pilot awarded one.
