He soon finds himself in a vale enclosed to the left, and in front and behind him by the Gualandra hills, bending round in a segment larger than a semicircle, and running down at each end to the lake, which obliques to the right and forms the chord of this mountain arc. The position cannot be guessed at from the plains of Cortona, nor appears to be so completely enclosed unless to one who is fairly within the hills. It then, indeed, appears "a place made as it were on purpose for a snare," locus insidiis natus. "Borghetto is then found to stand in a narrow marshy pass close to the hill, and to the lake, whilst there is no other outlet at the opposite turn of the mountains than through the little town of Passignano, which is pushed into the water by the foot of a high rocky acclivity." There is a woody eminence branching down from the mountains into the upper end of the plain nearer to the side of Passignano, and on this stands a white village called Torre. Polybius seems to allude to this eminence as the one on which Hannibal encamped, and drew out his heavy-armed Africans and Spaniards in a conspicuous position.[1] From this spot he despatched his Balearic and light-armed troops round through the Gualandra heights to the right, so as to arrive unseen and form an ambush amongst the broken acclivities which the road now passes, and to be ready to act upon the left flank and above the enemy, whilst the horse shut up the pass behind. Flaminius came to the lake near Borghetto at sunset; and, without sending any spies before him, marched through the pass the next morning before the day had quite broken, so that he perceived nothing of the horse and light troops above and about him, and saw only the heavy-armed Carthaginians in front on the hill of Torre. The consul began to draw out his army in the flat, and in the mean time the horse in ambush occupied the pass behind him at Borghetto. Thus the Romans were completely enclosed, having the lake on the right, the main army on the hill of Torre in front, the Gualandra hills filled with the light-armed on their left flank, and being prevented from receding by the cavalry, who, the further they advanced, stopped up all the outlets in the rear. A fog rising from the lake now spread itself over the army of the consul, but the high lands were in the sunshine, and
- ↑ Hist., lib. iii. cap. 83. The account in Polybius is not so easily reconcilable with present appearances as that in Livy; he talks of hills to the right and left of the pass and valley; but when Flaminius entered he had the lake at the right of both.
