Heraclea.
Fought 313, between the Illyrians, under Licinius, afterwards Emperor of the East, and the troops of the reigning Emperor Maximinus. Licinius was marching with 30,000 men to the relief of Heraclea, when he was attacked by Maximinus, with 70,000. Licinius was at first driven back by weight of numbers, but his skill, and the steadiness of his troops, enabled him to rally, and eventually Maximinus was defeated with heavy loss.
