On 19 February, while Wilson was attending to duties in Java, Darwin suffered a massive air raid. The Allies suffered significant losses: at least 236 civilians and military personnel were killed, 11 vessels were sunk in Darwin Harbour and 31 aircraft were destroyed. The only fighter aircraft present, a squadron of P-40E Warhawks of the United States Army Air Force, were overwhelmed and/or destroyed on the ground. By the end of March Allied resistance in the Dutch East Indies had collapsed by the end of March, and ABDA was dissolved, along with its sub-commands. Criticised regarding their preparations for and responses to the first air raids, Wilson, his deputy, Group Captain Frederick Scherger, and the station commander of RAAF Darwin, Wing Commander Sturt Griffith, were posted out of NWA.
