The siege having been impeded by so many disadvantages, the soldiers, although they were retarded during the whole time by the mud, cold, and constant showers, yet by their incessant labor overcame all these obstacles, and in twenty-five days raised a mound three hundred and thirty feet broad and eighty feet high.
His tot rebus impedita oppugnatione milites, cum toto tempore frigore et assiduis imbribus tardarentur, tamen continenti labore omnia haec superaverunt et diebus XXV aggerem latum pedes CCCXXX, altum pedes LXXX exstruxerunt.
When it almost touched the enemy's walls, and Caesar, according to his usual custom, kept watch at the work, and encouraged the soldiers not to discontinue the work for a moment: a little before the third watch they discovered that the mound was sinking, since the enemy had set it on fire by a mine;
Cum is murum hostium paene contingeret, et Caesar ad opus consuetudine excubaret militesque hortaretur, ne quod omnino tempus ab opere intermitteretur, paulo ante tertiam vigiliam est animadversum fumare aggerem, quem cuniculo hostes succenderant,
and at the same time a shout was raised along the entire wall, and a sally was made from two gates on each side of the turrets.
eodemque tempore toto muro clamore sublato duabus portis ab utroque latere turrium eruptio fiebat.
Some at a distance were casting torches and dry wood from the wall on the mound, others were pouring on it pitch, and other materials, by which the flame might be excited, so that a plan could hardly be formed, as to where they should first run to the defense, or to what part aid should be brought.
Alii faces atque aridam materiem de muro in aggerem eminus iaciebant, picem reliquasque res, quibus ignis excitari potest, fundebant, ut quo primum curreretur aut cui rei ferretur auxilium vix ratio iniri posset.
However, as two legions always kept guard before the camp by Caesar's orders, and several of them were at stated times at the work, measures were promptly taken, that some should oppose the sallying party, others draw back the towers and make a cut in the rampart; and moreover, that the whole army should hasten from the camp to extinguish the flames.
Tamen, quod instituto Caesaris semper duae legiones pro castris excubabant pluresque partitis temporibus erant in opere, celeriter factum est, ut alii eruptionibus resisterent, alii turres reducerent aggeremque interscinderent, omnis vero ex castris multitudo ad restinguendum concurreret.
