Here they were joined by the troops that had wintered at Placentia.
In the spring, Hannibal, instead of attempting to pursue his march by either of the highways which were fortified, outflanked the Romans by turning aside into Etruria.

His route led through a marshy and unhealthy country, and many soldiers perished.

Hannibal himself lost an eye from ophthalmia.

When he had arrived at Faesulae a report of his course first reached Flaminius, who at once broke camp and endeavored to intercept his enemy.

Hannibal, however, had the start, and was now near LAKE TRASIMENUS.
Here was a pass with a high hill on one side and the lake on the other.
Hannibal, with the flower of his infantry, occupied the hill.
