Mesca Ulad (English: The Intoxication of the Ulaid; the Ulstermen) is a narrative from the Ulster Cycle preserved in the 12th century manuscripts the Book of Leinster and in the Lebor na hUidre. The title Mesca Ulad occurs only in the Book of Leinster version. The story is set during Samhain, and follows the Ulaid as they attempt to attend two feasts in the same night: the first at Dún Dá Bhenn (modern day County Londonderry) to the north, and the second at Cúchulainn's fortress in Dún Delgan (modern Dundalk, Co. Louth) to the east. The men become intoxicated at the first feast and head south towards Kerry by accident. In Kerry, they are shown false hospitality by their traditional enemies the Munstermen, who offer them a place to stay. The Ulaid accept, and the Munstermen light a bonfire beneath the wood and iron structure. The Ulaids survive. Manuscript sources Book of Leinster (LL): p 261b-268b (RIA). Second part missing.
