Chapter V · (continued 2)

Ties between Britons and Gauls.

For, if their material culture was somewhat less advanced, the Britons, at least those of the south-eastern districts, naturally remained connected by the closest ties with the Gauls, and particularly with the Belgae. The Britons of Kent were little less civilized than the Gauls;1274 and Belgic kings, like William the Conqueror and his descendants, ruled on both sides of the Channel.1275 Not many years before the period of the Gallic wars, Diviciacus, king of the Suessiones, who governed directly the country round Soissons, had established supremacy not only over a large part of the surrounding Belgic territory but also over Britain;1276 and during a period which may have coincided with his reign gold coins of certain types were used indifferently in the Belgic districts of Britain and of Gaul, and were doubtless struck for rulers who had possessions in both.1277 But the power of Diviciacus had ended with him;1278 and when Caesar came to Gaul, the tribes of South-Eastern Britain were divided into antagonistic groups, headed respectively by the Catuvellauni and the Trinovantes. Cassivellaunus, the king of the Catuvellauni, was the ablest and most aggressive of the British princes of his time; but his opponents were supported, it would seem, by the influence of Commius, a chieftain of the Belgic Atrebates, whose territory comprised adjacent districts of the departments of Pas-de-Calais and Nord, and who were connected with the British tribe of the same name.

How the Britons were affected by Caesar’s campaigns in Gaul.

But, if anything could induce the Britons to forget their differences, it was the news which reached them of Caesar’s movements in Gaul. The events of the first year of his pro-consulship—the overthrow of the Helvetii, who had migrated into Gaul from Switzerland, and the defeat of the German invader, Ariovistus—might not affect their interests: but in the following year, when the Belgae banded together against the Roman conqueror, it was time for them to be on the alert. British adventurers crossed the Straits to assist their kinsmen; and when Caesar shattered the forces of the coalition, the leaders of at least one Belgic tribe fled over sea to escape his vengeance. Late in the autumn of that year or early in the following spring rumours reached the ports of the Channel that Caesar purposed to invade Britain.
