But Alfred, sensible that the proper method of opposing an enemy who made incursions by sea, was to meet them on their own element, took care to provide himself with a naval force,[*] which, though the most natural defence of an island, had hitherto been totally neglected by the English. He increased the shipping of his kingdom both in number and strength, and trained his subjects in the practice as well of sailing as of naval action. He distributed his armed vessels in proper stations around the island, and was sure to meet the Danish ships, either before or after they had landed their troops, and to pursue them in all their incursions. Though the Danes might suddenly, by surprise, disembark on the coast, which was generally become desolate by their frequent ravages, they were encountered by the English fleet in their retreat; and escaped not, as formerly, by abandoning their booty, but paid, by their total destruction, the penalty of the disorders which they had committed. [* Asser. p. 9. M. West. p. 179.] In this manner Alfred repelled several inroads of these piratical Danes, and maintained his kingdom, during some years, in safety and tranquillity. A fleet of a hundred and twenty ships of war was stationed upon the coast; and being provided with warlike engines, as well as with expert seamen, both Frisians and English, (for Alfred supplied the defects of his own subjects by engaging able foreigners in his service,) maintained a superiority over those smaller bands, with which England had so often been infested.[*] [* Asser. p. 11.
