Logistical modelling of a sea-borne expedition in the Mediterranean: the case of the Byzantine invasion of Crete in AD 960

Abstract

The Byzantine invasion of Crete in AD 960 provides a good opportunity to re-examine questions about the relative ease of supplying pre-modern armies by water in the Mediterranean basin. A combination of documentary, historical, and archaeological evidence suggests that the logistics behind supply by sea is more difficult than previously supposed. The army of Nikephoros Phokas besieged Chandax from July 960 to March 961 and had trouble supplying themselves with resources from the island. This paper creates a simple logistical model to get a sense of what the expedition required in terms of victuals and examines how they reached the army. The model suggests that previous work done on military supply in the classical period cannot be applied wholesale to the medieval Mediterranean.
