## Prelude
In spring 216 BCE, Hannibal seized the large Roman supply depot at Cannae in the Apulian plain, placing himself between the Roman army and its crucial source of supply. Polybius noted this "caused great commotion in the Roman army." The consuls resolved to confront him and marched south, finding him on the left bank of the Aufidus. [^4]

The Senate had deployed an unprecedented eight legions — roughly 86,000 men — determined to end the war decisively. Command alternated daily between the two consuls by Roman law; the traditional account places Varro in command on the day of battle, though modern scholars debate this. [^4]

- Roman advance pushed the center back into a concave shape, drawing them in
- Carthaginian flanks and cavalry closed the trap in a complete double envelopment
- Hasdrubal commanded the Carthaginian heavy cavalry; Maharbal led the Numidian cavalry [^3]
- Roman losses: ~50,00070,000 killed (Polybius: 70,000; Livy: ~48,200) — the worst single-day defeat in Roman history [^2][^4]; ~10,00019,000 captured; survivors fled to Canusium
- Among the Roman dead: 80 senators or men of senatorial rank, 2 quaestors, 29 of 48 military tribunes, and the previous year's consul Gnaeus Servilius Geminus [^4]
- Carthaginian losses: ~5,7008,000 (Polybius: 5,700; Livy: ~8,000), mostly the Gauls who formed the front lines [^1][^4]

## Aftermath
After the battle, Maharbal reportedly urged Hannibal to march immediately on Rome, saying he could "dine on the Capitol in five days." Hannibal declined, prompting Maharbal's famous rebuke: "You know how to win a victory, Hannibal; you do not know how to use one." [^1]

Hannibal's decision not to march on Rome was strategically considered: his army was depleted from the battle, Rome still commanded vast manpower reserves, and his strategic aim was to strip Rome of its Italian allies rather than besiege the city itself. [^2][^4]
## Legacy
- Hannibal's double envelopment became the gold standard of tactical warfare
- Despite the victory, Hannibal could not take Rome itself
- Rome eventually adopted Fabian attrition strategy and won the war

## Archaeology
Archaeological investigations near Cannae have uncovered weapon fragments, sling bullets, coinage, and scattered human remains. Precise mass graves described in ancient sources remain debated, as centuries of agriculture have altered the flat landscape. Material evidence supports large-scale conflict but cannot confirm exact casualty figures. [^3]
