1. ↑ Antigonus, who had made preparations to celebrate great games and a festival in Antigonia, had collected from all sides the most famous athletes and artists to compete for great prizes and fees. But when he heard of the crossing of Lysimachus and the desertion of his own generals, he abandoned the games but distributed to the athletes and artists not less than two hundred talents as compensation.  He himself taking his army set out from Syria and made a rapid march against the enemy. Arriving at Tarsus in Cilicia, he paid the army for three months from the money he had brought down from Cyinda. Apart from this fund, he was carrying three thousand talents with the army in order that he might have this provision whenever he had need of money. Then, crossing the Taurus Range, he marched toward Cappadocia; and, advancing upon those who had deserted him in upper Phrygia and Lycaonia, he restored them again to the former alliance.  At this very time Lysimachus, on hearing of the presence of the enemy, held a council considering how he ought to meet the approaching dangers. They decided not to join in battle until Seleucus should come down from the upper satrapies, but to occupy strong positions and, after making their encampment safe with palisade and ditch, to await the onslaught of the enemy. They therefore carried out their decision with vigour; but Antigonus, when he came near the enemy, drew up his army and challenged them to battle. When no one dared to issue forth, he himself occupied certain places through which it was necessary that the provisions of his opponents should be transported; and Lysimachus, fearing that if their food supply should be cut off, they would then be at the mercy of the enemy, broke camp at night, made a forced march of four hundred stades, and camped near Dorylaeum;  for the stronghold had an ample store of grain and other supplies, and a river ran by it that could give protection to those who camped beside it. Pitching camp, they strengthened their encampment with a deep ditch and a triple stockade.
