Táin Bó Cúalnge from the Book of Leinster (Author: [unknown])

section 12

After a fortnight the men of the four great provinces of Ireland came to the encampment together with Medb and Ailill and the men who were bringing the bull. But the bull's herdsman did not allow them to carry off Donn Cúailnge, so despite him they urged on both bull and heifers by beating their shields with sticks, and drove them into a narrow pass, and the cattle trampled the body of the herdsman thirty feet into the ground and made small fragments of his body. Forgemen was his name.

Bás Forgaimin is the name of that tale in the Foray of Cúailnge.
