HMS Oxley

HMS "Oxley" was an O class submarine built by Vickers-Armstrong Limited at Barrow-in-Furness in England, launched on 29 June 1926 and commissioned on 1 April 1927 for the Royal Australian Navy as HMAS "Oxley". HMAS "Oxley" paid off on 9 April 1931 and transferred to the Royal Navy on 10 April 1931.

HM Submarines "Oxley" and HMS "Triton" were patrolling off Norway on 10 September 1939 and had been in regular contact when "Triton" spotted an unidentified submarine off the coast of Norway. Believing it might be Oxley a number of signals of recognition were flashed by "Triton". No reply was forthcoming and after several challenges "Triton" fired two torpedoes that struck the submarine and sent her to the seabed. "Triton" closed in on the area and found three survivors. A Board of Enquiry found that "Oxley" was some way out of position and that "Triton" had acted correctly and was not culpable for the sinking.
