^Justinian himself took the field only once, during a campaign against the Huns in 559, when he was already an old man. This enterprise was largely symbolic and although no battle was fought, the emperor held a triumphal entry in the capital afterwards. (See Browning, R. Justinian and Theodora. London 1971, 193.)

^John L. Teall, "The Barbarians in Justinian's Armies", in Speculum, vol. 40, No. 2, 1965, 294–322. The total strength of the Byzantine army under Justinian is estimated at 150,000 men (J. Norwich, Byzantium: The Early Centuries, 259).
^While he glorified Justinian's achievements in his panegyric and his Wars, Procopius also wrote a hostile account, Anekdota (the so-called Secret History), in which Justinian is depicted as a cruel, venal, and incompetent ruler.
