Question: Which country was Thordön repaired in after being salvaged on August 4th? Passage 1:Robertson was born in Scotland, and attended King’s College in Auckland, New Zealand. where his father, the Scotsman, Charles Alexander Robertson had been Headmaster. After studying accountancy he went into business with Nello Porter and W. H Hemingway forming an accounting firm, publishing house and correspondence school specialising in accountancy and business courses. They later split the business, and following an expansion to Australia he set up permanently in Melbourne in 1913. Robertson built the Melbourne headquarters at Bank House in Bank Place, Collins Street and opened offices throughout Australia and later operations in North America and the United Kingdom. In Britain he was made Vice President of the Royal Institute of Commerce from 1929 to 1930, a Fellow of the Society of Incorporated Accountants and Auditors and a Fellow of the Royal Society of the Arts. Following his return to Australia, Robertson was embroiled in a landmark High Court tax case, which contested his income in Britain. Ironically, it was his close friend Justice Owen Dixon who fined Robertson, and arranged for him to help amend the loophole in the Commonwealth tax laws. Afterwards it is rumored Robertson was satirically made to play left-handed (his non-preferred) against Dixon in a round of golf, which being ambidextrous he still won. A keen speculator and prudent investor, Robertson had far reaching pecuniary interests and directorial roles in mining, wheat and wool, as well as educational links through his Hemingway Robertson Institute with the University of Melbourne. He was made president of the Stock Exchange of Melbourne from 1934 to 1936, managing the formation of the Australian Associated Stock Exchanges (AASE) which opened in 1937. In his later years and up until his death, Robertson was a Victorian representative, and first chairman of the Melbourne branch, of the Liberal Party of Australia, and a confidant of Robert Menzies. Robertson was an important figure in the 1949 Australian federal election, and defeat of Ben Chifley, where Menzies and the newly formed Liberal Party won power in a massive landslide, scoring a 48-seat swing—still the largest defeat of a sitting government at the federal level in Australia.
 Passage 2:Thordön (later spelled Tordön) was laid up in reserve in 1868 and 1869. She was rearmed with 240-millimeter M/69 guns (serial numbers 5 and 6) in 1872, but was laid up again from 1874 to 1882. The ship ran aground and sank on Lilla Rimö Island, off Norrköping, on 23 July 1883. She was salvaged on 4 August and managed to proceed under her own power to Karlskrona Naval Dockyard for repairs. The subsequent court-martial ordered the ship's captain to pay for the costs of the salvage and repairs, despite a misplaced buoy that caused the ship to ground. She was recommissioned in 1885 and 1888–89 before being placed back in reserve. Tordön was reconstructed in 1903–05; she received a pair of new Bofors M/94 guns that were given elevation limits of −7° and +15°. The ship also received eight 57-millimeter guns and new boilers. She was reactivated during World War I and assigned to the Gothenburg local defense flotilla in company with her sister Tirfing. Both ships were decommissioned in 1922 and sold the following year. Their new owner converted them into barges and used them in Stockholm harbor.
 Passage 3:In September she was part of the covering force for the Salerno landings, but by the end of the year had been transferred to the Bay of Biscay to carry out anti-blockade-runner patrols, as part of Operation Stonewall. However, she soon returned to the Mediterranean, this time for Operation Shingle, the Anzio landings, in January 1944. In June 1944 she covered the landings in Normandy as part of Force D off Sword Beach, then carried out offensive patrols of the Brittany coast in August to mop up the remnants of the German shipping in the area. Operating with destroyers, she sank Sperrbrecher 157 on 14/15 August and during the battle of Battle of Audierne Bay sank five Vorpostenboote on 22/23 August. After this she returned to the Home Fleet, covering the carrier raids along the Norwegian coast and making anti-shipping strikes. On the night of 27/28 January 1945, in company with the cruiser , she fought the Action of 28 January 1945 with German destroyers in which was badly damaged. Following this action she was refitted at Cammell-Laird's between February 1945 and March 1946.
