by the battlecruiser , destroying the external ballast tanks on K22s starboard side. Despite the damage, both submarines remained afloat, with K22 making her way back to port under her own power. On hearing distress signals from the two submarines, Commander E. Leir aboard Ithuriel decided to turn the Flotilla back to go to the assistance of K14 and K22. This put the flotilla on a collision course with the rest of the fleet, including the 12th Submarine Flotilla. On meeting the fleet, Ithuriel had to turn to avoid the battlecruiser , which took the flotilla directly into the path of the 12th Flotilla. Fearless collided with K17, which sank, then K4, following Fearless, pulled out of line and stopped to avoid hitting K17 and Fearless, and was herself hit by K6, which cut K4 in two, and K7. Two submarines had been sunk with 103 killed. K22 remained part of the 13th Flotilla at the end of the war, and by March 1919 was part of the 3rd Submarine Flotilla. She was sold for scrap on 16 December 1926. Memorials The war graves and a monument to those who lost their lives in the K13 sinking was erected by the ship's company, of the submarine depot at Fort Blockhouse, Gosport. It is to be found at the entrance to Faslane Cemetery, at the head of the Gare Loch. A memorial to the disaster was erected in Carlingford, New South Wales, Australia, paid for by the widow of Charles Freestone, a leading telegraphist on K13 who survived the accident to later emigrate and prosper in Australia. The memorial was unveiled on 10 September 1961 and has the inscription "This memorial has been created in memory of those officers and men of the Commonwealth who gave their lives in submarines while serving the cause of freedom." Set inside a pool of water surrounded by stone, it is composed of large (taller than a man) white letters saying "K13". There is a further memorial in Elder Park, Govan, opposite the Fairfield shipyard.
