Had his object merely been to harden the army by bold razzias and to procure booty for the soldiers, or even to eclipse the march of Metellus into the desert by an expedition going still farther, this method of warfare might be allowed to pass unchallenged; but the main object to be aimed at, and which Metellus had steadfastly and perseveringly kept in view—­ the capture of Jugurtha—­was in this way utterly set aside.  The expedition of Marius to Capsa was a venture as aimless, as that of Metellus to Thala had been judicious; but the expedition to the Molochath, which passed along the border of, if not into, the Mauretanian territory, was directly repugnant to sound policy.  King Bocchus, in whose power it lay to bring the war to an issue favourable for the Romans or endlessly to prolong it, now concluded with Jugurtha a treaty, in which the latter ceded to him a part of his kingdom and Bocchus promised actively to support his son-in-law against Rome.  The Roman army, which was returning from the river Molochath, found itself one evening suddenly surrounded by immense masses of Mauretanian and Numidian cavalry; they were obliged to fight just as the divisions stood without forming in a proper order of battle or carrying out any leading command, and had to deem themselves fortunate when their sadly-thinned troops were brought into temporary safety for the night on two hills not far remote from each other.  But the culpable negligence of the Africans intoxicated with victory wrested from them its consequences; they allowed themselves to be surprised in a deep sleep during the morning twilight by the Roman troops which had been in some measure reorganized during the night, and were fortunately dispersed.  Thereupon the Roman army continued its retreat in better order and with greater caution; but it was yet again assailed simultaneously on ail the four sides and was in great danger, till the cavalry officer Lucius Cornelius Sulla first dispersed the squadrons opposed to him and then, rapidly returning from their pursuit, threw himself also on Jugurtha and Bocchus at the point where they in person pressed hard on the rear of the Roman infantry.  Thus this attack also was successfully repelled; Marius brought his army back to Cirta, and took up his winter quarters there (648-9).

Negotiations with Bocchus

Strange as it may seem, we can yet understand why the Romans now, after king Bocchus had commenced the war, began to make most zealous exertions to secure his friendship, which they had at first slighted and thereafter had at least not specially sought; by doing so they gained this advantage, that no formal declaration of war took place on the part of Mauretania.  King Bocchus was not unwilling to return to his old ambiguous position:  without dissolving his agreement with Jugurtha or dismissing him, he entered into negotiations with the Roman general respecting the terms of an alliance with Rome.  When they were agreed or
