There are various other substantial evidences of great ancient intercourse of Essex with the Hoo of Kent, by a trajectus at this place, between East Tilbury and Higham; and Higham is only five miles from Rochester bridge, by which the Watling Street entered that city. Morant says, of the manor of Southall in East Tilbury, “This estate goes now to the repair of Rochester bridge: when and by whom given we do not find.”[65] He also mentions the “famous Higham Causeway” in connection with Tilbury.[66] Until the reign of Stephen, the church at Higham had belonged to the Abbot and Convents of St. John, Colchester.[67] The importance of this Essex traject to the kingdoms north of the Thames, when the domination of Mercia in Essex and Kent was beginning, may be inferred from the fact that one of the two colleges, or capitular churches, founded by Cedda, A.D. 653, in Essex, was at Tilbury.[68] There is a place called Chadwell by West Tilbury. Some years later, A.D. 676, when Æthelred of Mercia first devastated Kent, it is evident that he used this passage; for the destruction of Rochester, five miles south of Higham and Cliffe, is the only one of his exploits, on that expedition, specified by name.[69] So late as A.D. 1203, Giraldus Cambrensis passed from Kent to Essex by Tilbury. These incidents, connecting Tilbury and Higham, may qualify the surprise that has hitherto troubled church historians at finding that “Clofeshoch,” at so early a date as A.D. 673, was appointed, at “Herutford,” as the place for future councils, even if Herutford had been Hertford, as some say. The conclusion that the line of approach, and of the first invasion of Kent by the Mercians, was by a passage from the Essex coast to Higham or Cliffe; and that the peninsula of Hoo, adjoining Rochester, had then and long after been the basis of their domination of that kingdom; had been already formed, from what has been already said. And it was at this point, that it was thought worth while to see what the chief county historians say about the two termini of the trajectus. This is Hasted’s statement:--
