The K13 Memorial Park was dedicated at Carlingford, in northern Sydney. The memorial was the idea of ex-Leading Telegraphist Charles Freestone, who had served in the ill fated HMS K13, which had sunk with heavy loss of life in January 1917. He later emigrated to Australia, and became a wealthy businessman. Freestone died in 1958 before the memorial was completed, but his widow ensured that it was finished. Although dedicated to the submarine K 13, the memorial has become the place of remembrance for all Commonwealth officers and sailors who have lost their lives while serving in submarines. A memorial service, by the Australian Submarine Squadron, is held there every year on 11 November.
