HMAS Warrego (U73)
HMAS "Warrego" (L73/U73), named for the Warrego River, was a sloop of the Royal Australian Navy (RAN). Construction. She was laid down by the Cockatoo Island Dockyard at Sydney on 10 May 1939, launched on 10 February 1940, and commissioned into the RAN on 21 August 1940. Operational history. "Warrego" served during World War II as an escort and patrol vessel escorting convoys, including the Pensacola Convoy, in Australian waters and the South-West Pacific. In late January 1942 the ship was assigned to the short lived American-British-Dutch-Australian Command. The ship was part  of the escort, led by with the destroyer and , for a convoy composed of , , , and leaving Darwin before two in the morning of 15 February for Koepang carrying troops to reinforce forces already defending Timor. By 11:00, the convoy was being shadowed by a Japanese flying boat that dropped some bombs without causing damage before departing. The next morning another shadowing aircraft had taken position and before noon the convoy was attacked by bombers and flying boats in two waves. After the attacks the convoy continued toward Timor for a few hours with "Houston" launching a scout plane seeking the  enemy position. ABDA suspected the presence of Japanese carriers, an imminent invasion of Timor and a support fleet lying in wait and thus ordered the convoy back to Darwin which it reached before noon on 18 February. "Warrego" was in Darwin the next day when the Japanese attacked the port and, though with a working party over the side, was one of the ships that got underway to contribute antiaircraft fire to the defense. The day after the attack, "Warrego" escorted the damaged "Swan" through Clarence Strait and then resumed antisubmarine patrol off the port. "Warrego" was escorting the Dutch  ship to Townsville when both ships were recalled to Port Moresby in order to form a convoy to bring forces to Milne Bay. With , "Warrego" escorted "Karsik" and Dutch ship in the first convoy into Milne Bay on 25 June 1942 with Australian troops, American engineers and supplies for the buildup of that base in preparation for port operations and airfield construction. "Warrego", disguised with greenery, stood by as "Karsik" unloaded supplies at an improvised wharf until both sailed for Australia on 28 June. By 11 July, the sloop was back, escorting the Dutch ship with Brigadier John Field and  the 7th Brigade Group embarked as Milne Force to protect airfields under construction. By late October "Warrego", , and were assisting the survey vessel in surveying a safe passage for large ships from Milne Bay to Cape Nelson in order to provide large ship support to the Buna campaign that led to "Karsik" delivering tanks to Buna and the supply convoys of Operation Lilliput. The ship earned five battle honours for her wartime service: "Darwin 1942", "Pacific 1941–45", "New Guinea 1942", "Lingayen Gulf 1945", and "Borneo 1945". Decommissioning and fate. "Warrego" was sold for scrapping in 1966. HMAS Warrego (U73) HMAS
