be abandoned and sunk. The destroyer began to recover the Australian survivors, but at 04:30, Patterson detected an approaching ship. The destroyer moved to investigate, at which point the unknown ship opened fire, and Patterson retaliated. It was quickly realised that the attacker was USS Chicago, which had mistaken Canberra for a damaged Japanese vessel, and both ships ceased fire. Patterson returned to continue the evacuation, and was aided by sister ship . While still afloat, and in no apparent danger of sinking, damage control and repair options were being evaluated. It was determined that Canberras engines could not be repaired by the 0630 deadline, and she was to be scuttled, instead of being towed over to Tulagi harbor for emergency repairs. She was torpedoed by the destroyer at 08:00, after 263 5-inch shells and four other torpedoes fired by failed to do the job, and sank at .Mellefont, Two ships called Canberra, p. 6 She was one of the first ships to be sunk in what was eventually named "Ironbottom Sound". Three US cruisers were also destroyed during the battle and a US destroyer damaged.

In recognition of the valour displayed by the Australian ship and her company, United States President Franklin Delano Roosevelt wished to commemorate the loss of HMAS Canberra by naming a US ship in her honour. The under-construction Baltimore-class cruiser Pittsburgh was selected to be renamed . The ship was launched on 19 April 1943 by (Alice,) Lady Dixon, the wife of Sir Owen Dixon, Australia's ambassador to the United States, and is the only United States warship to be named after a foreign capital city. Around the same time, the British government announced that the heavy cruiser (a sister ship to Canberra, but of the London subclass) would be transferred to the RAN as a gift. Although King George VI had announced that the ship would be renamed Canberra, the duplication of ship names with the United States Navy was against RAN policy. Although it was thought that Australia had a greater claim to the name, the Australian
