The Danish raids also, though they were frequent up and down this coast, seem to have passed by Lynton; the narrowness of the landing beach, the steep rise of the cliffs immediately from the shore, the rocky bed of the river and the thick woods which fence the valley, all made it difficult of attack, while Porlock and Ilfracombe lay within a few miles, offering smoother harbours and easier access. There are several notices in the Saxon Chronicle of Danish raids on the coasts of the Severn Sea, in A.D. 845 and in A.D. 917, when the Lidwiccas, under Ohtor and Rhoald, landed and devastated a great portion of this north-west country, but they probably came to Watchet, near Minehead, and even then all that Lynton saw of the fierce raid was the smoke of the beacon fires from Dunkery Beacon to Martinhoe Beacon, near Heddon's Mouth. In the twelfth century the manors of Lynton and Countisbury were in the possession of Henry de Tracy, Becket's murderer, and by him were given to the Abbey of Ford, in whose right they remained until the dissolution of the monasteries by Henry VIII. Ford Abbey was a foundation of Cistercian monks, an order which was always engaged in matters of practical value, and under their rule something was done to improve the breed of mountain sheep round this district and produce wool of greater market value; they also attempted some development of agriculture and the fishery of Lynmouth. They had, indeed, extensive rights of fishery by land and sea--a very valuable asset, it must be remembered, in the Middle Ages, when the mass of the population lived almost exclusively on salt fish, and meat was scarce, except on the tables of the noble. Their rights extended over Lynmouth, Martinhoe, Countisbury, and the coast of Wales, and the monopoly of deep-sea fishing along the Severn Sea. This went beyond the old manorial claim, which was "from the shore so far seaward as a horsed knight could, at low water-springs, reach with his spear." Beyond was the King's, and was free and open to all his subjects, though a claim for deep-sea rights was allowed if it could be proved to be of very ancient usage, as in the case of Ford Abbey. Lynmouth was a noted resort for herrings all through the Middle Ages, and curing-houses stood on the beach for many years until 1607, when nearly all were swept away by a great storm, and never after properly reconstructed. The herrings also at some time in the seventeenth century left these coasts completely--tradition says because of the avarice of a parson of Lynton, a hard man and greedy, who cared rather to fleece his flock than feed them, and who imposed such heavy tithes on his poor parishioners, that, in spite of the prosperity of their fishing, they were unable to pay them. So the herrings left the district, and the parson could whistle for them, until he mended his ways and reduced his tithes, when they magically returned.
