Conceptual diagram: Roman infantry faces a forward-curving Carthaginian centre, with Carthaginian infantry on either wing.

A centre pushed forward

Hannibal places his central infantry ahead of the wings. The curved line faces the Roman advance.

Conceptual diagram: Roman infantry advances into the space left by the retreating centre. Carthaginian wings remain on both sides.

The advance draws inward

As the centre falls back, the Romans press into it. The African infantry now stands on either side of the advancing Roman formation.

Conceptual diagram: Carthaginian infantry turns inward against the Roman flanks while cavalry approaches from the rear.

Pressure from both sides and behind

The African infantry turns against the Roman flanks. Carthaginian cavalry attacks the rear, completing the encirclement.

Read the atlas explanation in full

Hannibal pushed his weakest troops forward in a crescent. As the massed Romans drove the center back, it bent inward by design; his veteran African infantry on the wings and his cavalry closed behind, sealing the Romans into a shrinking pocket where numbers became a death trap.

Read the account behind the drawing

The story retains this atlas's existing account. The movement diagrams also follow Polybius, Histories III.113–116, which describes the centre, flanking infantry and cavalry at the rear.

Polybius offers an ancient narrative, not an eyewitness battlefield plan. The drawings simplify that account; they do not independently establish troop positions or intentions.
