17. Orosius Anti-pagan History 5.18.22
In 89 BC a Roman army was on its way to lay siege to Pompeii. One of Sulla's subordinate officers, the ex-consul Postumius Albinus, was a man of intolerable arrogance and had so aroused the hatred of his soldiers that he was stoned to death. Sulla called the gods to witness that a citizen's blood could only be expiated by that of the enemy. His conscience-ridden army entered the battle thinking for each of them the outcome had to be victory or death. 18,000 Samnites were killed in that battle.
