After this, ioining certeine vessels togither, he caused a bridge to be made in the riuer of Meneth, into the which an other small riuer falleth that riseth at the roots of those hilles of Snowdone, to kéepe the enimies from lodging on the further side of that riuer. This bridge conteining roome for thréescore armed men to passe afront, was made ouer the riuer of Sient, by the which men saile into the Isle, which by the course of the sea ebbeth and floweth euerie twelue houres. But so it came to passe, that before the bridge was well boorded ouer, whilest the king yet remained at Aberconwaie, diuerse of the English nobilitie, to the number of seauen banerets with thrée hundreth armed men rashlie passed ouer, and as they surueied the foot of the mounteine, the tide began to come in so swiftlie, that where the Englishmen were aduanced a good prettie waie from the water side, they could not now get backe againe to the bridge which as yet was not fullie made vp. [Sidenote: The Englishmen distressed by Welshmen.] [Sidenote: The lord Clifford.] [Sidenote: _Chron. Dunst._] The Welshmen perceiuing this, came downe beside the mounteine, and assailed the Englishmen verie fiercelie, and with their great multitude so oppressed them, that for feare the Englishmen were driuen to take the water, and so by reason they were loaden with armour, manie of them were drowned: and amongst other, that famous knight sir Lucas de Thanie, Robert Clifford, sir William Lindsey, and two gentlemen of good accompt that were brethren to Robert Burnell as then bishop of Bath. There perished in all (as some saie) thirtéene knights, seuentéene yoong gentlemen, and to the number of two hundred footmen. Yet sir William Latimer, as good hap would, escaped, and diuerse other. This mischance happened on S. Leonards day. [Sidenote: The earle of Glocester maketh warre on the Welshmen.] [Sidenote: An. Reg. 11.] [Sidenote: Leolin inuadeth the kings fréends.] [Sidenote: The lord Gifford and Mortimer.]
