Apollodorus Epitome 1.21:
And Theseus allied himself with Pirithous, when he engaged in war against the centaurs. For when Pirithous wooed Hippodamia, he feasted the centaurs because they were her kinsmen. But being unaccustomed to wine, they made themselves drunk by swilling it greedily, and when the bride was brought in, they attempted to violate her. But Pirithous, fully armed, with Theseus, joined battle with them, and Theseus killed many of them (original Greek).
Plutarch Theseus 30.3:
After this, when Peirithous was about to marry Deidameia, he asked Theseus to come to the wedding, and see the country, and become acquainted with the Iapithae. Now he had invited the Centaurs also to the wedding feast. And when these were flown with insolence and wine, and laid hands upon the women, the Lapithae took vengeance upon them. Some of them they slew upon the spot, the rest they afterwards overcame in war and expelled from the country, Theseus fighting with them at the banquet and in the war (original Greek).
*Isokrates Helen 26:
And after this, allying himself with the Lapiths, he took the field against the Centaurs, those creatures of double nature, endowed with surpassing swiftness, strength, and daring, who were sacking, or about to sack, or were threatening, one city after another. These he conquered in battle and straightway put an end to their insolence, and not long thereafter he caused their race to disappear from the sight of men (original Greek).
Diodorus Siculus Bibliotheca Historica 4.70.3-4:
 Afterwards, when they had reconciled, Peirithous married Hippodameia, the daughter of Boutes, and he called both Theseus and the Centaurs to the wedding. They say that the drunken Centaurs attacked the female guests and lay with them by force, on account of which violation Theseus and the angered Lapiths killed not a few [Centaurs] and drove the rest out of the city.  For this reason, after the armies of the Centaurs were joined against the Lapiths and after they slew many [of them], those remaining fled to Pholoe of Arkadia. Finally, after escaping to Malea, they settled there. The Centaurs, excited by their success and having begun again from Pholoe, plundered Greek passers-by and killed many of their neighbors (translated by Aaron J. Ivey).
