The Battle of Cannae was a major battle of the Second Punic War, taking place on August 2, 216 BC near the town of Cannae in Apulia in southeast Italy.
At Cannae, the Roman infantry was formed in a formation not dissimilar from the Greek phalanx.
Following Cannae, the Roman army gradually developed into a professional force: the nucleus of Scipio's army at Zama was composed of veterans who had been fighting the Carthaginians in Hispania for nearly sixteen years, and had been molded into a superb fighting force.
