Fabius respected Hannibal's military skill and so refused to meet him in a pitched battle.
Instead, he kept his troops close to Hannibal, hoping to exhaust him in a long war of attrition.
Fabius was able to harass the Carthaginian foraging parties, limiting Hannibal's ability to wreak destruction, while conserving his own military force.
The delaying tactics involved not directly engaging Hannibal, while also exercising a "scorched earth" practice to prevent Hannibal's forces from obtaining grain and other resources.

The Romans were unimpressed with this defensive strategy and at first gave Fabius his epithet Cunctator (delayer) as an insult.
The strategy was in part ruined because of a lack of unity in the command of the Roman army, since Fabius' Master of the Horse, Minucius, was a political enemy of Fabius.
At one point, Fabius was called by the priests to assist with certain sacrifices, and as such, Fabius left the command of the army in the hands of Minucius during his absence.
Fabius had told Minucius not to attack Hannibal in his absence, but Minucius disobeyed and attacked anyway.
The attack, though of no strategic value, resulted in the retreat of several enemy units, and so the Roman people, desperate for good news, believed Minucius to be a hero.
On hearing of this, Fabius became enraged, and, as Dictator, could have ordered Minucius' execution for his disobedience.
One of the Plebeian Tribunes (chief representatives of the people) for the year, Metilius, was a partisan of Minucius, and as such he sought to use his power to help Minucius.
The Plebeian Tribunes were the only magistrates independent of the Dictator, and so with his protection, Minucius was relatively safe.
Plutarch states that Metilius "boldly applied himself to the people in the behalf of Minucius", and had Minucius granted powers equivalent to those of Fabius.
By this, Plutarch probably means that as a Plebeian Tribune, Metilius had the Plebeian Council, a popular assembly which only Tribunes could preside over, grant Minucius quasi-dictatorial powers.

Fabius did not attempt to fight the promotion of Minucius, but rather decided to wait until Minucius' rashness caused him to run headlong into some disaster.
He realized what would happen when Minucius was defeated in battle by Hannibal.
Fabius, we are told, reminded Minucius that it was Hannibal, and not he, who was the enemy.
Minucius proposed that they share the joint control of the army, with command rotating between the two every other day.
Fabius rejected this, and instead let Minucius command half of the army, while he commanded the other half.
Minucius openly claimed that Fabius was cowardly because he failed to confront the Carthaginian forces.
Near the present-day town of Larino in the Molise (then called Larinum), Hannibal had taken up position in a town called Gerione.
In the valley between Larino and Gerione, Minucius decided to make a broad frontal attack on Hannibal's troops.
Several thousand men were involved on either side.
It appeared that the Roman troops were winning, but Hannibal had set a trap.
Soon the Roman troops were being slaughtered.
Upon seeing the ambush of Minucius' army, Fabius cried "O Hercules!
how much sooner than I expected, though later than he seemed to desire, hath Minucius destroyed himself!"
On ordering his army to join the battle and rescue their fellow Romans, Fabius exclaimed "We must make haste to rescue Minucius, who is a valiant man, and a lover of his country."

Fabius rushed to his co-commander's assistance and Hannibal's forces immediately retreated.
After the battle, there was some feeling that there would be conflict between Minucius and Fabius; however, the younger soldier marched his men to Fabius' encampment and is reported to have said, "My father gave me life.
Today you saved my life.
You are my second father.
I recognize your superior abilities as a commander."
When Fabius' term as Dictator ended, consular government was restored, and Gnaeus Servilius Geminus and Marcus Atilius Regulus assumed the consulship for the remainder of the year.
