The Siege of Numantia was the culminating and pacifying action of the long-running Numantine War between the forces of the Roman Republic and those of the native Celtiberian population of Hispania Citerior. The Numantine War was the third of the Celtiberian Wars and it broke out in 143 BC. A decade later, in 133 BC, the Roman general and hero of the Third Punic War, Scipio Aemilianus Africanus, subjugated the chief Celtiberian city of Numantia.



Roman preparation

In late 135, the Roman Senate reappointed Scipio consul on popular demand and sent him to Hispania to finish what lesser generals had failed to complete. Scipio found morale low among the troops stationed in Iberia. The chance of plunder being low, there were few enticements to enlistment. Scipio nevertheless raised an army of 20,000 with 40,000 allied and mercenary troops, especially Numidian cavalry led by Jugurtha. The troops were trained hard by constant marching and there were several successful skirmishes before Scipio began to surround the city of Numantia itself. He planned only to starve it out and not to storm it.
