The German torpedo boat T23 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine (German Navy) during World War II. Completed in mid-1942, the boat was stationed in France later that year where she escorted blockade runners and U-boats through the Bay of Biscay. T23 also laid minefields in the English Channel in mid-1943. She participated in the Battle of Sept-Îles and the Battle of the Bay of Biscay later that year, neither receiving nor inflicting any damage.
After returning to Germany in early 1944, the boat was assigned to support German operations in the Baltic Sea. She escorted convoys and larger warships bombarding Soviet troops as well as bombarding them herself. In May T23 helped to evacuate troops and refugees from advancing Soviet forces. The boat was allocated to Great Britain after the war, but she was transferred to France in 1946. The French Navy renamed her L'Alsacien and recommissioned her in 1949. After serving with different units of the Mediterranean Squadron, she was condemned in 1954 and subsequently sold for scrap.
