During the Saxon period, the neighbouring coast was particularly subject to the invasions of the Danes, concerning whom so much has been written. In 787, the Danes, Northern men, or Normans, landed at Portland from three ships, to reconnoitre the country, which they did without interruption, as the Saxons had neglected their marine. A. D. 833, according to the ''Saxon Chronicle'', though some of our historians place the event in 831 or 832, a dreadful battle was fought at Charmouth. The Danes having met with repulses in other parts of the kingdom sailed to Charmouth where having landed, Speed says, "they made cruel ravage and slaughter." Their fleet consisted of 35 ships, containing a powerful army: their whole force, Huntingdon remarks, must have amounted to 17,500 men; other writers have estimated their numbers at about 15,000. Egbert collected the whole force of the county, and marched to attack them, after they had continued their ravages, according to Matthew of Westminster, about a twelve month. The king had nearly succeeded in cutting them off as they were forming; he threw them into great confusion, but continual supplies of men from the ships turned the scale in their favour. The Saxons were routed: the night alone prevented their destruction by the infuriated invaders, by the favour of which, Speed says, the king hardly escaped. Among the number of the slain were two earls, his principal officers, Dudda and Osmond, Wigen, bishop of Sherborne, and Hereferth, bishop of Winton. The Danes, finding a settlement would be liable to the attacks of the brave Egbert, retired to their ships with precipitation, and set sail. They continued to hover about the coast. In 840, they effected a landing on the same spot, (set Carrum,) from the same number of ships. Ethelwulf's army, which he headed in person, advanced to encounter them: a bloody battle ensued, which, after a desperate struggle, terminated in the Danes remaining masters of the field, though they shortly afterwards retired without any spoil. A successive series of invasions followed.
