First raid The four Japanese aircraft carriers launched 188 aircraft on the morning of 19 February. The main objective of their crews was attacking ships and port facilities in Darwin Harbour. On their way to Darwin, Zeros shot down a US Navy
PBY Catalina and strafed a USAAF
C-47 Skytrain on the ground, near
Melville Island. At 9.35 am Father McGrath of the Sacred Heart mission on
Bathurst Island, who was also an Australian
coastwatcher, sent a message using a
pedal radio to the Amalgamated Wireless Postal Radio Station at Darwin that a large number of aircraft were flying overhead and proceeding southward. The message was then relayed to the Royal Australian Air Force Operations at 9.37 am. No general alarm was given until about 10 am as the RAAF officers there wrongly judged that the aircraft which had been sighted were the ten USAAF P-40s, which were returning to Darwin at the time after reports of bad weather forced them to abort a flight to Java via Kupang, West Timor. As a result, the air raid sirens at Darwin were not sounded before the raid. Flying escort in a Zero fighter,
Petty Officer Yoshikazu Nagahama was separated from his squadron while he was attacking the PBY flying boat and arrived over the city alone ahead of the strike force, which was making a turn to attack from the south. He engaged five
US Army Air Force P-40 Warhawk fighters and single-handedly shot down four of them. The Japanese raiders began to arrive over Darwin at 9:58 am. HMAS
Gunbar was the first ship to be attacked, being strafed by several Zero fighters. At about this time, the town's air raid sirens were belatedly sounded. The Japanese bombers then conducted dive bombing and level bombing attacks on the ships in Darwin Harbour. These attacks lasted for 30 minutes, and resulted in the sinking of three warships and six merchant vessels, and damage to another ten ships. sank later. At least 21 labourers working on the wharf were killed when it was bombed. Japanese aircraft bombed and
strafed the base and civil airfield, as well as the town's army barracks and oil store. All of these facilities were seriously damaged. The bombers began to leave the Darwin area at about 10:10. On their way back to the carriers, their crews noted two Philippine-registered freighters lying just outside the port:
Florence D. and
Don Isidro. This information contributed to planning for the second raid that afternoon (which sank both vessels). Japanese losses may have been as few as five aircraft and three crew. Another 34 Japanese aircraft landed safely with battle damage. Warrant Officer Katsuyoshi Tsuru and First Petty Officer (1st class) Takezo Uchikado were killed when their Aichi dive bomber (bu. no.
3304; tail no. AII-254) crashed near RAAF Darwin. In 2013, a reference was discovered in Japanese records to a Nakajima torpedo bomber suffering wheel damage from a "gunshot" and both crew (names unknown) being rescued after ditching (by the destroyer ). Toyoshima's Zero is considered to have been brought down by small arms fire from
Sappers Tom Lamb and Len O'Shea of the
19th Battalion. possibly from a major Australian Army camp at
Winnellie. The bombers left the Darwin area at about 12:20 pm. Lewis and Ingman list 30 aircraft destroyed. The Japanese carrier force launched a small number of D3A dive bombers during the afternoon of 19 February to attack the
Florence D. and
Don Isidro.
Don Isidro was the first of these two ships to be attacked, and was rapidly sunk north of Melville Island. Eleven of her 84-strong crew were killed. The dive bombers also attacked
Florence D. and sank her off
Bathurst Island with the loss of four crewmen. All of the survivors from
Don Isidro were rescued by the corvette on 20 February. Some of
Florence D.s survivors landed on Bathurst and Melville Islands while the remainder were rescued by
Warrnambool on 23 February. Among the survivors of
Florence D. were the rescued crew of a US Navy
PBY piloted by then Lt
Thomas H. Moorer (later to become
Chairman of the US Joint Chiefs of Staff).
Admiral Halstead, strafed and with plates damaged by near misses, was brought to the pier where US Army volunteers along with survivors of the US and Philippine vessels helped unload her 14,000 drums of aviation gasoline. ==Aftermath==
