Military Iranian Mission, which had been put in place to deliver Lend-Lease supplies before the United States had entered the World War. The mission was originally commanded by Colonel Don G. Shingler, who was then replaced late in 1942 by Brigadier General Donald H. Connolly. Both the Iran-Iraq Service Command and the PGSC were subordinate to the U.S. Army Forces in the Middle East (USAFIME). PGSC was eventually renamed simply the Persian Gulf Command. Statistics Of the 17.5 million long tons of U.S. Lend-Lease aid provided to Russia, 7.9 million long tons (45%) were sent through Iran. In addition to the Persian Corridor the Americans used Arctic Convoys to the ports of Murmansk and Archangelsk and Soviet shipping carried supplies from the west coast of the United States and Canada to Vladivostok in the Far East, since the Soviet Union was not at war with Japan until August 1945. The Persian Corridor was the route for 4,159,117 long tons (4,225,858 metric tonnes) of this cargo. However, this was not the only allied contribution via the Persian Corridor. About 7,900,000 long tons (8,000,000 metric tonnes) of shipborne cargo from Allied sources were unloaded in the Corridor, most of it bound for the USSR - but some of it for British forces under the Middle East Command, or for the Iranian economy, which was sustaining the influx of tens of thousands of foreign troops and Polish refugees. Also, supplies were needed for the development of new transportation and logistics facilities in Persia and in the Soviet Union. The tonnage figure does not include transfers of warplanes via Persia. Supply routes Supplies came from as far away as Canada and the United States, and those were unloaded in Persian Gulf ports in Iran and Iraq. Once the Axis powers were cleared from the Mediterranean Sea in 1943 - with the Allied capture of Tunisia, Sicily, and southern Italy - cargo convoys were able to pass through the Mediterranean, the Suez Canal, and the Red Sea to Iran for shipment to the USSR. The main ports in the Corridor for supplies inbound to Iran were: in Iran, Bushehr Bandar Shahpur (now Bandar Imam Khomeini); and in Iraq, Basra Umm Qasr. The main overland routes were from the ports to Tehran, and then Tehran — Ashgabat or Tehran — Baku or, alternatively, Basra — Kazvin or Dzhulfa — Beslan. The main port for outbound supplies
