n two steep mountain walls, closed at
its outlet by a high hill, and at its entrance by the Trasimene lake.
With the flower of his infantry he barred the outlet; the light troops
and the cavalry placed themselves in concealment on either side. The
Roman columns advanced without hesitation into the unoccupied pass;
the thick morning mist concealed from them the position of the enemy.
As the head of the Roman line approached the hill, Hannibal gave the
signal for battle; the cavalry, advancing behind the heights, closed
the entrance of the pass, and at the same time the mist rolling away
revealed the Phoenician arms everywhere along the crests on the right
and left. There was no battle; it was a mere rout. Those that
remained outside of the defile were driven by the cavalry into the
lake. The main body was annihilated in the pass itself almost without
resistance, and most of them, including the consul himself, were cut
down in the order of march. The head of the Roman column, formed of
6000 infantry, cut their way through the infantry of the enemy, and
proved once more the irresistible might of the legions; but, cut off
from the rest of the army and without knowledge of its fate, they
marched on at random, were surrounded on the following day, on a
hill which they had occupied, by a corps of Carthaginian cavalry,
and--as the capitulation, which promised them a free retreat, was
rejected by Hannibal--were all treated as prisoners of war. 15,000
Romans had fallen, and as many were captured; in other words, the
army was annihilated. The slight Carthaginian loss--1500 men--again
fell mainly upon the Gauls.(3) And, as if this were not enough,
immediately after the battle on the Trasimene lake, the cavalry of
the army of Ariminum under Gaius Centenius, 4000 strong, which Gnaeus
Servilius had sent forward for the temporary support of his colleague
while he himself advanced by slow marches, was likewise surrounded by
the Phoenician army, and partly slain, partly made prisoners. All
Etruria was lost, and Hannibal might without hindrance march on Rome.
The Romans prepared themselves for the worst; they broke down the
bridges over the Tiber, and nominated Quintus Fabius Maximus dictator
to repair the walls and conduct the defence, for which an army of
reserve was formed. At the same time two new legions were summoned
under arms in the room of those annihilated, and the fleet, which
might become of importance in the event of
