That is quite a bit. Here is a brief description of him.
He was perfect in the use of arms, an accomplished rider, and able to endure fatigue beyond all belief. On a march he used to go at the head of his troops, sometimes on horseback, but oftener on foot, with his head bare in all kinds of weather. He would travel post in a light carriage without baggage, at the rate of one hundred miles per day; and if he was stopped by floods in the rivers, he swam across, or floated on skins inflated in the wind, so that he often anticipated the tidings of his movements.
Often he rallied his troops by his own personal exertions, stopping those who fled, keeping others in their ranks, and seizing men by the throat, turned them again towards the enemy, although numbers [of his men] were [sometimes] so terrified that an eagle bearer thus stopped made a thrust at him with the spearhead (on the eagle), and another on a like occasion left the standard in his hand."
