[3] After reducing the last holdouts of Maxentius' partisans, the victor addressed a friendly dispatch to Licinius, arranging to meet him at Milan where the Illyrian emperor was to wed his sister, in a formal ratification and celebration of their alliance.

[5] Meanwhile, Maximinus, on the basis of his agreement with Maxentius, had been mobilizing for war, though he concealed his intentions from Licinius with carefulness and success; as soon as his forces were prepared, though it was the middle of winter, he marched hurriedly with his army of 70,000 men through Anatolia from Antioch, arriving opposite Byzantium while the Illyrian emperor was still at Milan.

[6] In spite of his marked numerical disadvantage, Licinius won a complete victory, shattering the eastern legions and reducing Maximinus to the inglorious expedient of flight.

[citation needed] After his defeat, Maximinus attempted to regroup, hoping to raise a new army with which to encounter Licinius; amongst other measures, he reversed his policy of persecuting Christians, which had only played to the favor of his rival.

[7] However, though his resources might have sufficed to prolong the war for a considerable time against Licinius,[8] and the latter apparently hesitated to pursue him, hostilities terminated with Daza's death of disease in Tarsus, Cilicia, several months after Tzirallum.
