II., ''Ancient History'', p. 119 The expansionist ambitions of Maxentius and Maximinus led to a bellicose alliance of these princes against Constantine and Licinius, with the understanding that Maxentius would conquer the western provinces of Europe, and Maximinus the east. Constantine, sensing the threat, in turn drew closer to Licinius, and having assured himself of the latter's overt neutrality and secret support, unexpectedly attacked Maxentius in 312. Constantine invaded Italy and defeated Maxentius in a lightning campaign which culminated in the

Maximinus' anxiety to catch Licinius unprepared had led to much equipment, not to mention morale, being lost in the winter march through the harsh provinces of Asia-Minor. As soon as Licinius received news of the enemy's attack, Licinius hastened from Milan to meet the invasion, assembling the resources of Illyria in his hurried course through the province.

had already pitched camp with his force at the second station, 18 miles further ahead. Because of the scant time allowed him for preparation, Licinius was outnumbered by over two-to-one, possessing only 30,000 soldiers. It is recorded that an attempt at negotiation took place before the conflict, but was broken off after bad faith was revealed on both sides, after which it was decided to settle the matter by arms. The battle location, Tzirallum, is identified with the contemporary town of Tzouroulon, which is the modern Turkish city of

The battle

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. The greater discipline and experience of Licinius and his army contributed to the victory of the Illyrian legions.

Aftermath

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

, which had only played to the favor of his rival. However, though his resources might have sufficed to prolong the war for a considerable time against Licinius, and the latter apparently hesitated to pursue him, hostilities terminated with Daza's death of disease in Tarsus, Cilicia, several months after Tzirallum. Upon his competitor's death, Licinius took over the eastern provinces without a struggle.Gibbon, p. 369. As a result of this victory, and Constantine's against
