The Gibraltar convoys of World War II were oceangoing trade convoys of merchant ships sailing between Gibraltar and the United Kingdom. Gibraltar convoy routes crossed U-boat transit routes from French Atlantic ports and were within range of Axis maritime patrol aircraft making these convoys vulnerable to observation and interception by bombers, submarines, and surface warships during the Battle of the Atlantic. OG convoys brought supplies from the United Kingdom to Gibraltar from September 1939 until September 1942. Beginning with Operation Torch, OG convoys were replaced by KM convoys transporting military personnel and supplies from the United Kingdom to and past Gibraltar into the Mediterranean Sea. HG convoys brought food, raw materials, and later empty ships from Gibraltar to the United Kingdom from September 1939 until September 1942. After Operation Torch, HG convoys were replaced by MK convoys returning mostly empty ships from the Mediterranean to the United Kingdom. KM and MK convoys ended in 1945.
