ordered his brother Mago with the cavalry to ride at the rear of the army.
As the march continued, it seemed that Hannibal was on his way to Rome. He passed the Roman camp where Flaminius, one of the new Consuls, was in command, and then continued southward, with no army now to hinder his approach to the city.
But what the great general was really trying to do was, not to reach Rome and besiege it, since for that he had not the necessary machines, but to entice the Roman army from its camp and force it to fight. All unwittingly, the army fell into the trap which the Carthaginian set.
Flaminius had been sent into Etruria to see that Hannibal did not march upon Rome. As he had allowed the enemy to pass his camp unhindered, he determined to atone for his error as well as might be, by following swiftly and destroying it.
The Consul was urged to wait until his colleague Servilius joined him, but this he was much too impatient to do.
Hannibal meanwhile had reached the Trasimenus Lake. Between the lake and the mountains ran a narrow road. The general saw at once that this was the very place in which to entrap the Roman army. So he sent his men to command the heights that overlooked the path.
That same evening, Flaminius encamped a short distance from the lake. He could see the narrow road stretching out before him.
Early in the morning the Romans were again on the march, hastening after the enemy that was, as they believed, on the way to Rome.
Unaware of evil, they marched along the narrow road by the side of the lake, scarce able to see a step before them, so heavy hung the mist on the pathway and along the foot of the mountains.
But up on the heights, where Hannibal had posted his men, the sun was shining bright.
