B.C. 53. BRITAIN BECOMES TRIBUTARY TO ROME. 107 which is now called Sandwich ; there he found Androgeus the duke of Trinovantum, who promised him faithful obedience, and pointed out to him with great prudence how he ought to proceed. In the meantime king Cassibelaunus had besieged the city of Trinovantum, but as soon as he heard of the arrival of Cassar he hastened to meet him. When therefore the opposing armies met in a certain valley near Dover, there ensued great bloodshed on each side. And after they had spent a great deal of the day in fighting, suddenly Androgeus appeared out of a certain wood which was near at hand, with five thousand armed men, and attacked the army of Cassibelaunus in the rear, and, although with great difficulty, routed it. But the king being compelled to flee with his army, occupied a high and precipitous mountain, which had on its summit a thick cover of hazel bushes, and was rocky ; and which had been used at times by the Britons for an encampment. Cassar therefore blockaded that mountain towards the close of day, and cut the enemy off from all means of escape. After a second day had elapsed, when Cassar was unable to compel the Britons to surrender, he determined to reduce them by famine, if Androgeus had not come to himself again, and felt some pity for his own nation. Consequently he came to Julius, and addressed him in this manner : " Behold you have now sufficiently avenged yourself on Cassibelaunus, and you have made all Britain subject to yourself by my assistance. Our omnipotent gods are not willing that I should allow my master to be condemned to a shameful death, or to be bound with chains. Have pity on him therefore, because he cannot be in danger as long as I am alive." Cassar therefore being moved to thoughts of peace by the request of Androgeus, came to a treaty in the terms that Cassibelaunus should promise to pay to Cassar from Britain, every year, three thousand pounds weight of silver, under the name of tribute. Then, having become friends, they gave one another mutual gifts. An d when seven more years had elapsed, Cassibelaunus died, and was buried in York. He was succeeded by Tennacius, the brother of Androgeus ; because Androgeus himself had gone to Borne with the Roman general.
