The Battle of Lycinius and Constantine

The two navies met near modern gallipoli, and by all appearances it looked like the stage was set for a great naval battle. But just prior to the engagement, a storm kicked up that hit lycinus fleet particularly hard. And the crews were so battered that when crispus advanced, the battle turned out to be little more than a mop up operation. It is reported that only four of lycinius ships escaped, undamaged or uncaptured. The sea now belonged to constantine.
