and Menapii) and tribes from Britain, in the uprising of the Veneti. Caesar wanted to induce fear in the northern Morini so "that they wouldn't attack him." The territory of the Morini and Menapii was well protected by marshes and woodland and suited for guerrilla tactics. The dangers outweighed the benefits of subduing those economically less interesting regions. In 55 BC Labienus tightened the Roman grip upon the strategically more important western side of the Morini tribal areas. In 54 BC Caesar let one legion, under the command of legate Caius Fabius, hibernate there. In 53 BC the Morini were joined most probably with the Menapii under the command of the Atrebate Commius. During the great Gallic rebellion led by Vercingetorix, the Morini, like many other Gaulish tribes, sent a contingent of some 5000 men to the relief force which had to liberate Alesia. Although Caesar fought the Morini, he managed to conquer only a part of their territory around Calais. The rest of the Morini were annexed by emperor Augustus between the years 33-23 B.C. Their tribal lands became part of the Roman province of Gallia Belgica, forming one district together with the Atrebates and Ambiani. The area was converted to Christianity by Saints Victoricus and Fuscian, but the region was re-evangelized by Saint Omer in the seventh century. Thérouanne became the capital of a medieval diocese which included the old territories of the Morini and Atrebates, as well as part of the old Menapian civitas.
