Today in History: HMS Oxley Was Sunk by Friendly Fire

On this day (September 10) in 1939, the British Royal Navy lost its first submarine, HMS Oxley, to friendly fire when HMS Triton fired on it off the coast of Norway. It was the beginning of World War II and Oxley was out of position and did not respond to four attempts to signal it. Two men survived the sinking of the Oxley.
