Marcus Claudius Marcellus vs Sad ibn Abi Waqqas

Marcellus was elected consul for the first time and campaigned in Cisalpine Gaul against the Insubres. He killed the Gallic chieftain Viridomarus in single combat, winning the spolia opima, a rare honor awarded for killing an enemy leader in battle.

After the disaster at Cannae, Marcellus defended the city of Nola against Hannibal's forces. He successfully repelled the Carthaginian attack, earning a reputation as one of the few Roman commanders able to stand up to Hannibal in the field.

Marcellus captured the Greek city of Syracuse after a two-year siege. The city had allied with Carthage, and its fall was a major blow to Hannibal's strategy. During the sack, the mathematician Archimedes was killed by a Roman soldier, despite Marcellus's orders to spare him.

While reconnoitering near Venusia, Marcellus and his colleague were ambushed by a Carthaginian force under Hannibal. Marcellus was killed in the skirmish, and his death was a significant loss for Rome. Hannibal reportedly gave him a proper burial.

Sa'd ibn Abi Waqqas commanded the Muslim Arab army against the Sassanid Persian forces at al-Qadisiyyah in Iraq. The Muslim victory broke the back of the Sassanid army and opened the way for the conquest of the Persian heartland.

Following al-Qadisiyyah, Sa'd ibn Abi Waqqas led the Muslim army to capture Ctesiphon, the capital of the Sassanid Empire. The city fell after a siege, yielding immense wealth and marking the effective end of Sassanid resistance.

Sa'd ibn Abi Waqqas was appointed governor of Kufa, the newly founded garrison city in Iraq. He administered the city and its surrounding territories, overseeing the settlement of Arab tribes and the administration of the conquered lands.
