20. With that small force he took several towns. The Sidetonians, Ausetanians, and Suessetanians came over to his side. [2] The Lacetanians, a remote and wild nation, still remained in arms; partly through their natural ferocity, and partly through consciousness of guilt, in having laid waste, by sudden incursions, the country of the allies, while the consul and his army were employed in the war with the Turditanians. [3] He therefore marched to attack their capital, not only with the Roman cohorts, but also with the troops of the allies, who were justly incensed against them. [4] The town [p. 1511]was stretched out into considerable length, but had not proportionable breadth. [5] At the distance of about four hundred paces from it he halted, and leaving there a party composed of chosen cohorts, he charged them not to stir from that spot until he himself should come to them; and then he led round the rest of the men to the farther side of the town. The greater part of his auxiliary troops were Suessetanians, and these he ordered to advance and assault the wall. [6] The Lacetanians, knowing their arms and standards, and remembering how often they had themselves, with impunity, committed every kind of outrage and insult in their territory, how often defeated and routed them in pitched battles, hastily threw open a gate, and all, in one body, rushed out against them. [7] The Suessetanians scarcely stood their shout, much less their onset; [8] and the consul, on seeing this happen, just as he had foreseen, galloped back under the enemy's wall to his cohorts, brought them up quickly to that part of the city where all [9??] was silence and solitude, in consequence of the Lacetanians having sallied out on the Suessetanians, and took possession of every part of it before the Lacetanians returned; who, having nothing now left but their arms, soon surrendered themselves also.
