So admirably disciplined were they, that sometimes, in battle, the mounted men would leap from their horses and advance as foot soldiers to aid the other infantry, leaving the horses to stand until they returned.

The horses would not move from the spot; the men, when the object for which they had dismounted was accomplished, would come back, spring to their seats again, and once more become a squadron of cavalry.
[Sidenote: Caesar's popularity with the army.] [Sidenote: Caesar's military habits.] [Sidenote: His bridge across the Rhine.] Although Caesar was very energetic and decided in the government of his army, he was extremely popular with his soldiers in all these campaigns.
He exposed his men, of course, to a great many privations and hardships, but then he evinced, in many cases, such a willingness to bear his share of them, that the men were very little inclined to complain.

He moved at the head of the column when his troops were advancing on a march, generally on horseback, but often on foot; and Suetonius says that he used to go bareheaded on such occasions, whatever was the state of the weather, though it is difficult to see what the motive of this apparently needless exposure could be, unless it was for effect, on some special or unusual occasion.

Caesar would ford or swim rivers with his men whenever there was no other mode of transit, sometimes supported, it was said, by bags inflated with air, and placed under his arms.

At one time he built a bridge across the Rhine, to enable his army to cross that river.
