Ex his omnibus longe sunt humanissimi qui Cantium incolunt, quae regio est maritima omnis, neque multum a Gallica differunt consuetudine.
[2][page needed] Caesar mentions four kings, Segovax, Carvilius, Cingetorix, and Taximagulus, who held power in Cantium at the time of his second expedition in 54 BCE.
The British leader Cassivellaunus, besieged in his stronghold north of the Thames, sent a message to these four kings to attack the Roman naval camp as a distraction.
The attack failed, a chieftain called Lugotorix was captured, and Cassivellaunus was forced to seek terms.
In the century between Caesar's expeditions and the conquest under Claudius (starting in 43 CE), kings in Britain began to issue coins stamped with their names.
