But about noone, when Cesar had sent foorth three legions of footemen and all his horssemen vnder the [Sidenote:  Caius Trebonius.] leading of his lieutenant Caius Trebonius to fetch in forrage, they suddenlie brake out on euerie side, and vpon the forragers.  The [Sidenote:  Dion Cassius saith, that the Britains vanquished the Roman footmen at this time, but were put to the worst by the horssemen.] Romans so far foorth as they might, not breaking their arraie, nor going from their ensignes or guidons, gaue the charge on them, and fiercelie repelled them, so that the horssemen hauing the legions of footemen at their backs, followed the Britains so long as they might haue the said legions in sight readie to succour them of need were:  by reason whereof, they slue a great number of the Britains, not giuing them leasure to recouer themselues, nor to staie that they might haue time to get out of their charrets.  After this chase and discomfiture, all such as were come from other parties to the aid of their fellowes departed home, & after that day the Britains aduentured to fight against Cesar with their maine power; and withdrawing beyond the riuer [Sidenote:  (which is to be supposed was at Kingston) or not far from thence.] of Thames, determined to stop the enimies from passing the same, if by anie meanes they might:  and whereas there was but one foord by the which they might come ouer, Cassibellane caused the same to be set full of sharpe stakes, not onlie in the middest of the water, but also at the comming foorth on that side where he was lodged with his armie in good order, readie to defend the passage.  Cesar learning by relation of prisoners which he tooke, what the Britains intended to doo, marched foorth to the riuer side, where the foord was, by the which his armie might passe the same on foot though verie hardlie.  At his comming thither, he might perceiue how the Britains were readie on the further side to impeach his passage, and how that the banke at the comming foorth of the water was pight full of sharpe stakes, and so likewise was the chanell of the riuer set with piles which were couered with the water.

These things yet staied not Cesar, who appointing his horssemen to passe on before, commanded the footemen to follow.  The souldiers entring the water, waded through with such speed and violence (nothing appeering of them aboue water but their heads) that the Britains were constreined to giue place, being not able to susteine the brunt of the Romane horssemen, and the legions of their footemen, and so abandoning the place betooke them to flight.  Cassibellane not minding to trie the matter anie more by battell, sent awaie the most part of his people, but yet kept with him about a foure thousand charretmen or wagoners, and still watched what waie the Romans tooke, coasting them euer as they marched, and kept somewhat aside within the couert of woods, and other combersome places.  And out of those quarters through which he vnderstood
