The Trinobantes having been defended and protected from all injury of the soldiers, the Cenimagni, Segontiaci, Ancalites, Bibroci, and Cassi send embassies and surrender themselves to Caesar. From them he learns that the town of Cassivellaunus, fortified by woods and marshes, into which a fairly large number of men and cattle had assembled, was not far from that place. Now the Britons call it a town, when they have fortified entangled woods with a rampart and a trench, where they have been accustomed to assemble for the purpose of avoiding an incursion of the enemy. Thither he marches with his legions; he finds the place excellently fortified by nature and by art; nevertheless, he endeavors to attack it from two sides. The enemy, having delayed for a short time, did not withstand the onset of our soldiers, and cast themselves out of the town on another side. A great number of cattle was found there, and many in their flight were overtaken and slain.
