 By the late 2nd century Chauci raiding was ongoing and more serious than before, continuing in the English Channel until their last recorded raids –175.While there are no historical sources to inform us one way or the other, it is likely that the Chauci continued their raiding and then played a role in the formation of the new Germanic powers, the Franks and Saxons who were raiders in the 3rd century.There is archaeological evidence of destruction by raiders between 170–200, ranging along the Continental coast down to the Bay of Biscay, to northwest Belgica (e.g., fire destruction at Amiens, Thérouanne, Vendeuil-Caply, Beauvais, Bavai, Tournai, and Arras), to coastal Britain (e.g., fire destruction at the Essex sites of Chelmsford, Billericay, Gestingthorpe, Braintree, Wickford, Kelvedon, Great Chesterford, and Harlow).
