Question: The Battle of Monte Porzio (also called the Battle of Tusculum) was fought on 29 May 1167 between the Holy Roman Empire and the Commune of Rome, comparing its effect on the city of Rome, one historian has been called Monte Porzio the "Cannae of the Middle Ages",which major battle of the Second Punic War that took place on 2 August 216 BC in Apulia, in southeast Italy, is called?
Context: Gaius Terentius Varro ( ; fl.  3rd century BC) was a Roman consul and commander.  Along with his colleague, Lucius Aemilius Paullus, he commanded at the Battle of Cannae in 216 BC, during the Second Punic War, against the Carthaginian general Hannibal.  The battle resulted in a decisive Roman defeat and his colleague Paulus's death and he was completely discredited by everyone upon returning to Rome due to his leadership and took no further part of the war. The Battle of the Rhône Crossing took place during the Second Punic War.  The Carthaginian army under Hannibal Barca, while marching to Italy in the autumn of 218 BC, fought an army of the gallic Volcae tribe on the east bank of the Rhone River possibly near Aurasio.  The pro-Roman Volcae, acting on behalf of a Roman army camped on the east bank near Massalia, intended to prevent the Carthaginians from crossing and invading Italy.  Devising a plan to circumvent the Volcae, the Carthaginians, before crossing the river to attack the Gauls, had sent a detachment upriver under Hanno, son of Bomilcar, to cross at a different point and take position behind the Gauls.  Hannibal led the main army across after Hanno sent smoke signals saying that the ambush was in place.  As the Gauls massed to oppose Hannibal’s force, Hanno attacked them from behind and routed their army.  Although the battle was not fought against a Roman army, the result of the battle had a profound effect on the war.  Had the Carthaginians been prevented from crossing the Rhone, the 218 invasion of Italy might not have taken place.  This is the first major battle that Hannibal fought outside the Iberian Peninsula. The Battle of Cannae ( or ) was a major battle of the Second Punic War that took place on 2 August 216 BC in Apulia, in southeast Italy.  The army of Carthage, under Hannibal, surrounded and decisively defeated a larger army of the Roman Republic under the consuls Lucius Aemilius Paullus and Gaius Terentius Varro.  It is regarded both as one of the greatest tactical feats in military history and as one of the worst defeats in Roman history. Villa Mondragone is a patrician villa originally in the territory of the Italian comune of Frascati (Latium, central Italy), now in the territory of Monte Porzio Catone (Alban Hills).  It lies on a hill 416m above sea-level, in an area called, from its many castles and villas, Castelli Romani about 20 km southeast of Rome, near the ancient town of Tusculum. Marcus Atilius Regulus (fl.  213 BC), a son of Marcus Atilius Regulus, the consul captured during the First Punic War, and a grandson of Marcus Atilius Regulus (consul 294 BC), was a Roman consul for the year 227 BC, together with Publius Valerius Flaccus, and was a consul "suffectus" in 217 BC, replacing Gaius Flaminius Nepos, who was killed in battle at Lake Trasimene.  Marcus Atilius Regulus agreed to accompany the consuls of 216 BC, Gaius Terentius Varro and Lucius Aemilius Paullus, along with the other surviving former consul of 217 BC, Gnaeus Servilius Geminus, when an army of 80,000 Romans and allies was amassed together to smash the Carthaginian army under Hannibal.  The historian Polybius records that both he and Servilius died fighting bravely at the Battle of Cannae. The Pentri (Greek: Πέντροι ) were a tribe of the Samnites, and apparently one of the most important of the subdivisions of that nation.  According to Salmon, their name comes from the Celtic pen- <peak>.  Their capital city was Bovianum Undecumanorum (Livy ix.  31), modern Bojano, in the very heart of the Samnite territory, and it is therefore probable that they occupied the whole of that rugged and mountainous district which extends from the frontiers of Latium, in the valley of the Liris (modern Liri), to those of the Frentani, towards the Adriatic Sea.  But it is impossible to determine their exact limits, or to separate their history from that of the remaining Samnites.  It is probable, indeed, that, throughout the long wars of the Romans with the Samnites, the Pentri were the leading tribe of the latter people, and always took part in the war, whether specified or not.  The only occasion when we hear of their separating themselves from the rest of their countrymen, is during the Second Punic War, when we are told that all the other Samnites, except the Pentri, declared in favour of Hannibal after the battle of Cannae, 216 BC.  (Liv.  xxii.  61.)  This is the last occasion on which we find their name in history; all trace of the distinction between them and the other Samnites seems to have been subsequently lost, and their name is not even mentioned by Strabo or Pliny. The quincunx was an ancient Roman bronze coin produced during the Roman Republic.  It was not part of the standard Roman monetary system.  It was only produced during the Second Punic War (218 to 204 BC), by mints at Luceria (mod.  Lucera), Teate (mod.  Chieti), Larinum (mod.  Larino), and northern Apulia.  A coin with the same value was minted in Capua, during the Second Punic War, after the defeat of Cannae. The Battle of Monte Porzio (also called the Battle of Tusculum) was fought on 29 May 1167 between the Holy Roman Empire and the Commune of Rome.  The communal Roman army, which one historian has called the "greatest army which Rome had sent into the field in centuries", was defeated by the forces of the Emperor Frederick Barbarossa and his local allies, the Counts of Tusculum and the ruler of Albano.  Comparing its effect on the city of Rome, one historian has been called Monte Porzio the "Cannae of the Middle Ages". The second battle of Herdonia took place in 210 BC during the Second Punic War.  Hannibal, leader of the Carthaginians, who had invaded Italy eight years earlier, encircled and destroyed a Roman army which was operating against his allies in Apulia.  The heavy defeat increased the war’s burden on Rome and, piled on previous military disasters (such as Lake Trasimene, Cannae and others), aggravated the relations with her exhausted Italian allies.  For Hannibal the battle was a tactical success, but did not halt for long the Roman advance.  Within the next three years the Romans reconquered most of the territories and cities lost at the beginning of the war and pushed the Carthaginian general to the southwestern end of the Apennine peninsula.  The battle was the last Carthaginian victory of the war; all battles which followed were either inconclusive or Roman victories. The Battle of Canusium was a three-day engagement between the forces of Rome and Carthage.  It took place in Apulia during the summer of 209 BC, the tenth year of the Second Punic War.  A larger Roman offensive, of which it was a part, aimed to subjugate and to punish cities and tribes that had abandoned the alliance with Rome after the Battle of Cannae, and to narrow the base of the Carthaginian leader, Hannibal, in southern Italy.
Answer: Battle of Cannae
