[1] Procopius, History of the Wars of Justinian 4.2.3 (web address 1); prior to the Battle of Tricamarum (location uncertain; about 50 km. west of Carthage; in the vicinity of present-day Chaouat, Tunisia) in December 533 CE, the Massagetai under Belisarios's command covertly adopt a position of neutrality between the Romans and the Vandals; cf. Kaldellis (195). For Gelimer cf. alpha 249; for Belisarios, beta 233; for the Massagetai cf. alpha 3460. Some 600 mounted archers from the Massagetai nation had accompanied the Roman army on the expedition from Byzantion to Carthage; cf. Procopius 3.11.11 (web address 2) and Kaldellis (169).
