As early as 911, Varangians are mentioned as fighting as mercenaries for the Byzantines. About 700 Varangians served along with Dalmatians as marines in Byzantine naval expeditions against the Emirate of Crete in 902 and a force of 629 returned to Crete under Constantine Porphyrogenitus in 949. A unit of 415 Varangians was involved in the Italian expedition of 936. It is also recorded that there were Varangian contingents among the forces that fought the Arabs in Syria in 955. During this period, the Varangian mercenaries were included in the "Great Companions" (Gr. Μεγάλη Εταιρεία).
