On the same day, informed by scouts that the enemy had encamped at the foot of a mountain 8 miles from his own camp, he [Caesar] sent persons [scouts] to find out what the nature of the mountain was, and of what kind of ascent there was around the sides.
It was reported to be easy.
During the third watch, he [Caesar] ordered Titus Labienus, his legate with praetor status, to climb the highest ridge of the mountain with two legions and those guides who knew the path; whom he shows his plans to.

Caesar led his forces up onto the nearest hill, he built up a battleline.

Late in the day, Caesar finally learnt from the spies that the mountain was held by his own men and that the Helvetians had moved camp and that Considius reported what he had not seen instead of what he had, because he was terrified by fear.
On that day in that interval which he had been accustomed to [the usual distance], he follows the
