King Regamon was not there that day. He was in the territory of the Corco Baiscinn at a meeting with the Fir Bolg. The alarm is raised after them in the territory. The news is told to Regamon. He goes in pursuit with his host. The whole pursuing party falls upon Maine Mórgar, and they thereby sustained an overpowering assault. ‘All gather then in one place,’ said Maine, ‘and let someone from them be sent with the cows in front of the warriors; and let the girls drive the cows across the ford to Crúachu; and tell Ailill and Medb the plight in which we are here.’ The girls arrive at Crúachu, and they tell the whole story. ‘There has been an attack upon your sons at Áth Briuin,’ said they, ‘and they asked for a party for their assistance.’
