The Ancient Irish Epic Tale Táin Bó Cúalnge

"Let us ask for a sword-truce from Cuchulain," said Ailill and Medb. Lugaid goes to him and Cuchulain accords the truce. "Put a man for me on the ford to-morrow," said Cuchulain. There happened to be with Medb six royal hirelings, to wit: six princes of the Clans of Deda, the three Dubs ('the Blacks') of Imlech, and the three Dergs ('the Reds') of Sruthair, by name. "Why should it not be for us," quoth they, "to go and attack Cuchulain?" So the next day they went and Cuchulain put an end to the six of them.2
