The third of July, 324 AD, dawned hot and clear over the plains of Thrace. For days, the two armies had faced each other across the Hebrus river, a tense, simmering stalemate. From his command post, Constantine stared at Licinius's camp, a formidable fortress crowning a hill on the far bank. His rival had chosen his ground with masterful skill, daring Constantine to attempt a suicidal frontal assault across the river and up the slope. A direct attack was unthinkable, a fool's gambit that would see his army slaughtered by the entrenched Danubian legions.
