On 30 April 313, the two armies clashed at the Battle of Tzirallum, and in the ensuing battle Daia's forces were crushed. The war between them only ended with Daia's death in August 313. In 314, a civil war erupted between Licinius and Constantine, in which Constantine used the pretext that Licinius was harbouring Senecio, whom Constantine accused of plotting to overthrow him.
