Not only had discipline ceased and the spoliation of Numidian townships and even of the Roman provincial territory become during the suspension of hostilities the chief business of the Roman soldiery, but not a few officers and soldiers had as well as their generals entered into secret understanding with the enemy.

It is easy to see that such an army could do nothing in the field; and if Jugurtha on this occasion bribed the Roman general into inaction, as was afterwards judicially asserted against the latter, he did in truth what was superfluous.
Spurius Albinus therefore contented himself with doing nothing.
On the other hand his brother who after his departure assumed the interim command--the equally foolhardy and incapable Aulus Postumius-- in the middle of winter fell on the idea of seizing by a bold coup de main the treasures of the king, which were kept in the town of Suthul (afterwards Calama, now Guelma) difficult of access and still more difficult of conquest.

The army set out thither and reached the town; but the siege was unsuccessful and without prospect of result, and, when the king who had remained for a time with his troops in front of the town went into the desert, the Roman general preferred to pursue him.

This was precisely what Jugurtha intended in a nocturnal assault, which was favoured by the difficulties of the ground and the secret understanding which Jugurtha had with some in the Roman army, the Numidians captured the Roman camp, and drove the Romans, many of whom were unarmed, before them in the most complete and disgraceful rout.

The consequence was a capitulation, the terms of which--the marching off of the Roman army under the yoke, the immediate evacuation of the whole Numidian territory, and the renewal of the treaty cancelled by the senate--were dictated by Jugurtha and accepted by the Romans (in the beginning of 645).
Dissatisfaction in the Capital This was too much to be borne.
