capture other cities in the region. Memnon of Rhodes (380–333 BC) was the commander of the Greek mercenaries working for the Persian King Darius III when Alexander the Great of Macedonia invaded Persia in 334 BC and won the Battle of the Granicus River. Alexander also employed Greek mercenaries during his campaigns. These were men who fought for him directly and not those who fought in city-state units attached to his army. Greek mercenaries in ancient India Tamil poems described the Greek soldiers who served as mercenaries for Indian kings as: "The valiant-eyed Yavanas (Greeks), whose bodies were strong and of terrible aspect". Alfred Charles Auguste Foucher said that some of the troops of Mara in the Gandhara sculptures may represent Greek mercenaries. Stephanus of Byzantium wrote about a city called Daedala or Daidala () in India, which he called Indo-Cretan, most probably because it was a settlement of Cretan mercenaries. Carthage Carthage contracted Balearic Islands shepherds as slingers during the Punic Wars against Rome. The vast majority of the Carthaginian military – except the highest officers, the navy, and the home guard – were mercenaries. Xanthippus of Carthage was a Spartan mercenary general employed by Carthage. Greek mercenaries were hired by Carthage to fight against the Dionysius I of Syracuse. Dionysius made Carthage pay a very high ransom for the Carthaginian prisoners, but he left the Greek mercenaries prisoners free without any ransom. This made the Carthaginians suspicious of their Greek mercenaries and discharged them all from their service. With this trick Dionysius did not have to fight again against the Greek mercenaries of Carthage who were very dangerous enemies. Byzantine Empire In the late Roman Empire, it became increasingly difficult for Emperors and generals to raise military units from the citizenry for various reasons: lack of manpower, lack of time available for training, lack of materials, and, inevitably, political considerations. Therefore, beginning in the late 4th century, the empire often contracted whole bands of barbarians either within the legions or as autonomous foederati. The barbarians were Romanized and surviving veterans were established in areas requiring population. The Varangian Guard of the Byzantine Empire is the best known formation made up of barbarian mercenaries (see next section). Other Members of independent Thracian tribes such as the Bessi and Dii often joined the ranks of large organized armies as mercenaries. The Sons of Mars were Italian mercenaries used by the
