It gave him the opportunity to intervene on the side of Carthage and seize territory in the Adriatic while Rome was tied up in the west. Of course this gave the Romans the excuse to attack and loot Macedonia after it had defeated Carthage.
How did the battle of Cannae affect the Roman empire
The battle of Cannae?
The Carthaginians, led by Hannibal, won the Battle of Cannae in 216 BC. The Carthaginians used a successful double envelopment strategy which resulted in a devastating defeat for the Roman army. It is considered one of the greatest tactical victories in military history.
Hannibal did not defeated Cannae. He defeated the troops of Rome and her allies at the battle of Cannae in 216 BC. This was one of the most brilliant tactical masterpieces in the history of Antiquity. The estimates of Roman and allied casualties by ancient historians range form 47,200 to 70,000. Some modern historians estimate figures between 10,500 and 16,000.
The Battle of Cannae (Hannibal's defeat of the Roman Army in 216 BCE.) In the US Civil war battle of 1862 the Union Army was trounced.
Hannibal's strategy at the Battle of Cannae was to use a double envelopment tactic. He positioned his infantry in a crescent shape, allowing the Roman forces to advance into the center while his flanks gave way. This created a trap, encircling the Roman army and putting them at a disadvantage. Hannibal's cavalry closed in from behind, causing chaos and ultimately leading to a decisive Carthaginian victory with the annihilation of the Roman forces.
Because they suck at fighting
The two worse military defeats of the Romans were the Battle of Cannae (216 BC) and the Battle of Adrianople (378 AD). More Romans and their allies died in the former, but the latter seriously weakened the Roman army of the Late Empire.
Rome became dominant in the Western Meditterranean, and became entangled in the Eastern Mediterranean.
The Roman army learnt that Quintus Fabius Maximus Cunctator had been right. He had said that the Roman army could not stand up to Hannibal in open battle and he adopted a strategy of attrition: tailing and harassing Hannibal and avoiding open battle to wear him down. Many Romans had become frustrated and impatient. The strategy clashed with their culture of aggressive war and wanted a head on clash which would give victory and a quick end of the war. This is what led to disaster at Cannae. The Romans reverted to the Fabian strategy.
The ancient Battle of Cannae took place on August 2, 216 BC. This was the Second Punic War and the leaders of the Roman forces were Consuls Gaius Terentius Varro and Lucius Aemilius Paullus. They were defeated by the forces of Carthage led by the famous general Hannibal.
The solution was not 'pagan'. To the ancient people pagan meant 'dwellers about' - that is the country people who did not worship at city temples. So describing the Roman religion as 'pagan' does not help understand their relationship with the gods, any more than questioning the Christian motivations for World War 2. The Romans and Greeks consulted the gods when faced with a serious problem, and as Chuck has explained, they did this as would be expected after the Cannae debacle.
