Julius Caesar's invasions of Britain
In the course of his Gallic Wars, Julius Caesar invaded Britain twice: in 55 and 54 BC. On the first occasion Caesar took with him only two legions, and achieved little beyond a landing on the coast of Kent. The second invasion consisted of 628 ships, five legions and 2,000 cavalry. The force was so imposing that the Britons did not dare contest Caesar's landing in Kent, waiting instead until he began to move inland. Caesar eventually penetrated into Middlesex and crossed the Thames, forcing the British warlord Cassivellaunus to surrender as a tributary to Rome and setting up Mandubracius of the Trinovantes as client king.
