Overview
Aulus Postumius Albinus (c. 151 – 89 BC) was a Roman senator and military commander. In 110 BC, he went to serve on the staff of his brother, Spurius, in the war against the Numidian king Jugurtha. Left in charge of the troops during the winter, Aulus decided on a rash foray which involved the army in a humiliating defeat and surrender. The disaster led to the establishment of a commission which condemned several prominent aristocrats of collusion with the enemy during the war. Aulus himself was seemingly not condemned, and went on to be elected consul a decade later, in 99 BC. In 89, Aulus held command of a fleet during the Social War in Italy, but proved to be an unpopular commander and was murdered by his troops.
Biography
Aulus Postumius Albinus belonged to a patrician family which had been prominent since the beginning of the Roman Republic. He was probably a son of Spurius Postumius Albinus Magnus, Roman consul in 148 BC. Aulus must have been born in or not long before 151 BC, and probably held the office of praetor by 111 BC. Cicero considered him a good public speaker.
In 110 BC, Aulus joined the staff of his older brother, the consul Spurius Postumius Albinus, as his pro-praetorian deputy, in a military expedition against the Numidian king Jugurtha. Spurius accomplished little and eventually had to return to Rome and oversee the election of next year's magistrates, leaving Aulus in charge of the Roman camp in Numidia. Problems with the elections forced Spurius to linger in Italy longer than expected, and, in early 109, despite it being winter, Aulus allowed himself to be tempted into a bold military move on his own against the town of Suthul, where Jugurtha's treasury was located. After the Romans failed to immediately take the town, they were successfully lured away by Jugurtha into a devastating ambush. The King forced Aulus into a humiliating treaty, by which the Romans would pass under the yoke and leave Numidia within 10 days.
