18 September – On this day
The battle of Chrysopolis took place near Chalcedon between two Roman emperors Constantine I and Licinius. In essence this war was one between the Christian faith and the pagan gods, represented by Constantine and Licinius respectively. Constantine managed to get his forces to Chrysopolis before Licinius and after seeking divine guidance Constantine launched a direct massive assault against Licinius routing his forces. Licinius is said to have lost approximately 30,000 troops in the engagement but managed to escape to Nicomedia with what remained of his army. Licinius, was promised his safety by Constantine and surrendered not long after, realising that he had no hope of victory. Constantine was as good as his word for some months before executing Licinius.
