 Julius Caesar described calling ships ad portum Itium (used twice) to embark troops for Caesar's invasions of Britain to Britain in 54 BC.It was certainly near the uplands round Cap Gris Nez ("Promunturium Itium"), but the exact site has been violently disputed ever since the Renaissance.Many critics have assumed that Caesar used the same port for his first expedition, but the name does not appear at all in that connection.
