After the war between Clusium and Rome failed to win back the throne for Tarquinius, he sought refuge with Mamilius in Tusculum.
Mamilius was wounded in the breast and taken to the rear, while Aebutius' arm was so severely injured by his opponent's lance that he had to withdraw from the field and direct his forces at a distance.
As he did so, he was recognized by the Roman general Titus Herminius, who charged so fiercely that he killed the Latin prince with a single thrust of his spear.
[6][7] The defeat of Octavius Mamilius and the Latin army at the Battle of Lake Regillus ended the last serious attempt by Tarquinius to regain the throne.
Lucius Mamilius, perhaps the grandson of Octavius, was dictator of Tusculum in 460 BC, and sent an army to assist the Romans in recovering the Capitol during a revolt.
