Great Generals: Hannibal takes on Rome - II , Battle of Lake Trasimene

Previous: Battle of Trebia

After the defeat at Trebia the Roman Senate was shocked. The reality of someone crossing the mountains and attacking them from the North was something they couldn't grasp. But still, they continued to underestimate Hannibal's strength (which wasn't just in numbers). The Senate decided to sack Sempronius (the defeated general of the previous battle) and brought in two new consuls: Gnaeus Servillius Geminius and Gaius Flaminius. Servillius was given charge of Scipio's army and Flaminius was made in charge of whatever was left of Sempronius's defeated army.

The job for Flaminius was to protect the city of Rome and prevent Hannibal from reaching the city. So he hurried his army back from Trebia towards Rome. But Hannibal followed him even faster and eventually overtook him. And before Flaminius could try to hurry back again, Hannibal cut him off using the first recorded Turning Movement in history. Hannibal's plan was to lure Flaminius into battle before he could reach Rome or receive help from Servillius. He started rampaging the countryside to provoke Flaminius. He hoped that destroying the very land that Flaminius was sent to protect will entice him into battle. And so it happened...

Flaminius like Sempronius was a rash and arrogant general. Even though all his advisers suggested that he only send his cavalry to temporarily stop Hannibal and wait for the other consul to arrive, Flaminius decided to take him on.

Meanwhile, Hannibal had come across a road that was bordered on one side by a Lake and hills on the other. In his eyes, this was the perfect place for an large-scale ambush.

Here is the Map of the area in the north of Lake Trasimene where Hannibal placed his trap. The waters of the lake have receded a little now, and so there is more space now between the hills and the lake than there was at that time.

In the cover of the night, Hannibal placed his cavalry and Gallic infantry in the hills where Romans would be entering the valley from. Their job was to suddenly attack the Romans from the left and close the way back. He hid his light troops along the hills all the way to Tuoro Hill. Finally, he himself stood with his heavy infantry on top of a slight elevation where Romans could see them. He also asked his soldiers to light massive campfires on Tuoro Hill at night, so that the Romans would imagine that he's far away.



The next morning, in the fog, when Romans started approaching the road from the West, Hannibal's trap was set. To further entice Flaminius, he sent a skirmish force ahead to start fighting and then retreat to lure the Romans deeper into the valley (and into his trap).

As soon as the Roman army entered the valley, Hannibal's cavalry crashed down upon them from the hills and closed the road behind them. Now the Romans were surrounded from all sides, with their backs to the lake. The battle started even before they had time to draw up their battle lines. The Roman army was split into three parts, the west, center and the east.

Hannibal's army quickly destroyed the west flank, and heavy infantry led by Hannibal crushed the east flank. Now the Roman center was exposed to attack from all sides. They fought for about three hours but the whole Roman army was completely annihilated.

Off the 40,000 soldiers that the Roman army had in the morning, 30,000 were either killed (by the afternoon) or drowned in the lake. A few soldiers who escaped were later captured by Hannibal's brother Mahirbal the next day. Flaminius himself didn't live to regret his decisions and leadership on that day. The massacre was so intense that the soldiers didn't even notice that an earthquake occurred that morning...

Compare Roman losses to those of Hannibal's forces who lost only 1,500 soldiers out of their original strength of 50,000.

Hannibal had now planned and executed the greatest ambush in history. But this was still not his best...

After the shock of another huge defeat, Romans first gave dictatorial powers to Fabius Maximus. Fabius was smarter than the other consuls before him, and knew that going head-to-head with Hannibal was a mistake. He implemented his 'Fabian Strategy' where he avoided direct battles and tried to wear Hannibal down by harassing him.



But the Roman people and the Senate didn't have the patience to keep this up. They again removed Fabius and got two new consuls Paullus and Varro. These two would lead Romans to their biggest defeat ever - at Cannae...
