Passage 3:Thordon (later spelled Tordon) 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 Rimo Island, off Norrkoping, 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 188889 before being placed back in reserve. Tordon was reconstructed in 190305; 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.
