A wandering squire who, with his companion Blat, made his way to Cornwall on the heels of Tristan’s near-capture:
Tristan had been chased through the woods, after leaving a tryst with Isolde, by Mark’s knight Andred. Tristan escaped by jumping into a boat and paddling off down a river. Isolde commissioned Haupt and Blat to assist in the matter by claiming it was they who Andred had chased, thus fooling Andred and Mark into thinking that Tristan had not been there.
