Several subsidiary SOE headquarters and stations were set up to manage operations which were too distant for London to control directly. SOE's operations in the Middle East and Balkans were controlled from a headquarters in Cairo, which was notorious for poor security, infighting and conflicts with other agencies. It finally became known in April 1944 as Special Operations (Mediterranean), or SO(M). Shortly after the Allied landings in North Africa, a station codenamed "Massingham" was established near Algiers in late 1942, which operated into Southern France. Following the Allied invasion of Italy, personnel from "Massingham" established forward stations in Brindisi and near Naples. A subsidiary headquarters initially known as "Force 133" was later set up in Bari in Southern Italy, under the Cairo headquarters, to control operations in the Balkans and Northern Italy.
