First he sent priuilie two hundred archers into a lowe medow, which was néere to the vauntgard of his enimies; but separated with a great ditch, commanding them there to kéepe themselues close till they had a token to them giuen, to let driue at their aduersaries: beside this, he appointed a vaward, of the which he made capteine Edward duke of Yorke, who of an haultie courage had desired that office, and with him were the lords Beaumont, Willoughbie, and Fanhope, and this battell was all of archers. The middle ward was gouerned by the king himselfe, with his brother the duke of Glocester, and the earles of Marshall, Oxenford, and Suffolke, in the which were all the strong bilmen. The duke of Excester vncle to the king led the rereward, which was mixed both with bilmen and archers. The horssemen like wings went on euerie side of the battell. [Sidenote: Archers the greatest force of the English armie.] [Sidenote: _Abr. Fl._ out of _Fabian_ pag. 392 and _Polychron._] [Sidenote: A politike inuention.] [Sidenote: _Hall._] Thus the king hauing ordered his battels, feared not the puissance of his enimies, but yet to prouide that they should not with the multitude of horssemen breake the order of his archers, in whome the force of his armie consisted [¶ For in those daies the yeomen had their lims at libertie, sith their hosen were then fastened with one point, and their iackes long and easie to shoot in; so that they might draw bowes of great strength, and shoot arrowes of a yard long; beside the head] he caused stakes bound with iron sharpe at both ends, of the length of fiue or six foot to be pitched before the archers, and of ech side the footmen like an hedge, to the intent that if the barded horsses ran rashlie vpon them, they might shortlie be gored and destroied. Certeine persons also were appointed to remooue the stakes, as by the mooueing of the archers occasion and time should require, so that the footmen were hedged about with stakes, and the horssemen stood like a bulwarke betwéene them and their enimies, without the stakes. This deuise of fortifieng an armie, was at this time first inuented: but since that time they haue deuised caltraps, harrowes, and other new engins against the force of horssemen; so that if the enimies run hastilie vpon the same, either are their horsses wounded with the stakes, or their féet hurt with the other engins, so as thereby the beasts are gored, or else made vnable to mainteine their course.
