Editing Antigonus I Monophthalmus (section)

==Satrap of Phrygia==
In 334 BC, Antigonus served as the commander of the allied Greek infantry, a division of Alexander's invasion army of the Persian Empire. Alexander did not trust his Greek infantry and had left them behind when he marched to confront the Western [[Satraps]]; therefore Antigonus did not participate in the [[Battle of the Granicus]]. When Alexander marched east, he appointed Antigonus as satrap of [[Phrygia]]. As Satrap of Phrygia, Antigonus besieged a garrison of mercenaries (1,000 Carians and 100 Greeks) the Persians had left behind and after their surrender he enrolled them in his service allowing him to send his own Greek troops (1,500 mercenaries) to reinforce Alexander for the major battle that was about to be fought at Issus.<ref>Richard A. Billows, ''Antigonos the One-Eyed'', 42; Curius IV 1,35.</ref> After the [[Battle of Issus]], he succeeded the Achaemenid satrap of Greater Phrygia, [[Atizyes]], who had died during the battle. Antigonus successfully performed his primary responsibility: to defend Alexander's lines of supply and communication during the latter's extended campaign against the Achaemenid [[Achaemenid Empire|Persian Empire]]. Following Alexander's [[Battle of Issus|victory at Issus]], part of the Persian army regrouped in Cappadocia and attempted to sever Alexander's lines of supply and communication running through the centre of Asia Minor; however, Antigonus defeated the Persian forces in three separate battles.<ref>Curtius Rufus, Historia Alexandri Magni, IV 34–35</ref> After defeating the Persian counter-attack, Antigonus focused on conquering the rest of Phrygia and maintaining Alexander's lines of communication and supply.
