With the insolence of an Oriental he sent a message to Belisarius, requiring him to have his bath prepared for the morrow, as after taking the town he would need that kind of refreshment.
Belisarius contented himself, in reply, with drawing out his troops in front of Daras in a position carefully prepared beforehand, where both his centre and his flanks would be protected by a deep ditch, outside of which there would be room to act for his cavalry.

Perozes, having reconnoitred the position, hesitated to attack it without a greater advantage of numbers, and sent hastily to Nisibis for 10,000 more soldiers, while he allowed the day to pass without anything more serious than a demonstration of his calvary against the Roman left, and some insignificant single combats.
The next morning his reinforcement arrived; and after some exchange of messages with Belisarius, which led to no result, he commenced active operations.

Placing his infantry in the centre, and his horse upon either wing, as the Romans had likewise done, and arranging his infantry so that one half should from time to time relieve the other, he assaulted the Roman line with a storm of darts and arrows.

The Romans replied with their missile weapons; but the Persians had the advantage of numbers; they were protected by huge wattled shields; and they were more accustomed to this style of warfare than their adversaries.

Still the Romans held out; but it was a relief to them when the missile weapons were exhausted on both sides, and a closer fight began along the whole line with swords and spears.
