Publius Decius Mus
When Pyrrhus invaded Apulia (279 BC), the two armies met in the Battle of Asculum, where Pyrrhus won a costly victory. The consul Publius Decius Mus was the Roman commander, and while his able force was ultimately defeated, they almost managed to break the back of Pyrrhus' Epirot army, guaranteeing the security of Rome itself. In the end, the Romans lost 6,000 men and Pyrrhus 3,500 including many officers. Pyrrhus later famously commented on his victory at Asculum, stating, "If we are victorious in one more battle with the Romans, we shall be utterly ruined". It is from reports of this semi-legendary event that the term Pyrrhic victory originates.
