XI.--These things being known [to him], Caesar orders the legions and cavalry to be recalled and to cease from their march; he himself returns to the ships: he sees clearly before him almost the same things which he had heard of from the messengers and by letter, so that, about forty ships being lost, the remainder seemed capable of being repaired with much labour. Therefore he selects workmen from the legions, and orders others to be sent for from the continent; he writes to Labienus to build as many ships as he could with those legions which were with him. He himself, though the matter was one of great difficulty and labour, yet thought it to be most expedient for all the ships to be brought up on shore and joined with the camp by one fortification. In these matters he employed about ten days, the labour of the soldiers being unremitting even during the hours of night. The ships having been brought up on shore and the camp strongly fortified, he left the same forces which he did before as a guard for the ships; he sets out in person for the same place that he had returned from. When he had come thither, greater forces of the Britons had already assembled at that place, the chief command and management of the war having been entrusted to Cassivellaunus, whose territories a river, which is called the Thames, separates from the maritime states at about eighty miles from the sea. At an earlier period perpetual wars had taken place between him and the other states; but, greatly alarmed by our arrival, the Britons had placed him over the whole war and the conduct of it. XII.--The interior portion of Britain is inhabited by those of whom they say that it is handed down by tradition that they were born in the island itself: the maritime portion by those who had passed over from the country of the Belgae for the purpose of plunder and making war; almost all of whom are called by the names of those states from which being sprung they went thither, and having waged war, continued there and began to cultivate the lands. The number of the people is countless, and their buildings exceedingly numerous, for the most part very like those of the Gauls: the number of cattle is great. They use either brass or iron rings, determined at a certain weight, as their money. Tin is produced in the midland regions; in the maritime, iron; but the quantity of it is small: they employ brass, which is imported. There, as in Gaul, is timber of every description, except beech and fir. They do not regard it lawful to eat the hare, and the cock, and the goose; they, however, breed them for amusement and pleasure. The climate is more temperate than in Gaul, the colds being less severe.
