had deposited at Sirmium.
Licinius passed through that city, and breaking down the bridge on the
Save, hastened to collect a new army in Dacia and Thrace. In his flight
he bestowed the precarious title of Caesar on Valens, his general of the
Illyrian frontier.

Chapter XIV: Six Emperors At The Same Time, Reunion Of The Empire.--Part
IV.

The plain of Mardia in Thrace was the theatre of a second battle no less
obstinate and bloody than the former. The troops on both sides displayed
the same valor and discipline; and the victory was once more decided
by the superior abilities of Constantine, who directed a body of five
thousand men to gain an advantageous height, from whence, during the
heat of the action, they attacked the rear of the enemy, and made a very

contempt. "It was not for such a purpose," he sternly replied, "that we
have advanced from the shores of the western ocean in an uninterrupted
course of combats and victories, that, after rejecting an ungrateful
kinsman, we should accept for our colleague a contemptible slave.
The abdication of Valens is the first article of the treaty." It was
necessary to accept this humiliating condition; and the unhappy Valens,

As soon as this obstacle was removed, the tranquillity of the Roman
world was easily restored. The successive defeats of Licinius had
ruined his forces, but they had displayed his courage and abilities. His
situation was almost desperate, but the efforts of despair are sometimes
formidable, and the
