In the time of Hengist and Horsa the creek was so considerable that its mouth furnished a sufficient harbor for their vessels. They landed at a town called Ebbs-fleet, which is now, however, at some distance inland. There is some uncertainty in respect to the motive which led Hengist and Horsa to make their first descent upon the English coast. Whether they came on one of their customary piratical expeditions, or were driven on the coast accidentally by stress of weather, or were invited to come by the British king, can not now be accurately ascertained. Such parties of Anglo-Saxons had undoubtedly often landed before under somewhat similar circumstances, and then, after brief incursions into the interior, had re-embarked on board their ships and sailed away. In this case, however, there was a certain peculiar and extraordinary state of things in the political condition of the country in which they had landed, which resulted in first protracting their stay, and finally in establishing them so fixedly and permanently in the land, that they and their followers and descendants soon became the entire masters of it, and have remained in possession to the present day. These circumstances were as follows: The name of the king of Britain at this period was Vortigern. At the time when the Anglo-Saxons arrived, he and his government were nearly overwhelmed with the pressure of difficulty and danger arising from the incursions of the Picts and Scots; and Vortigern, instead of being aroused to redoubled vigilance and energy by the imminence of the danger, as Alfred afterward was in similar circumstances, sank down, as weak minds always do, in despair, and gave himself up to dissipation and vice--endeavoring, like depraved seamen on a wreck, to drown his mental distress in animal sensations of pleasure. Such men are ready to seek relief or rescue from their danger from any quarter and at any price. Vortigern, instead of looking upon the Anglo-Saxon intruders as new enemies, conceived the idea of appealing to them for succor. He offered to convey to them a large tract of territory in the part of the island where they had landed, on condition of their aiding him in his contests with his other foes. Hengist and Horsa acceded to this proposal. They marched their followers into battle, and defeated Vortigern's enemies. They sent across the sea to their native land, and invited new adventurers to join them. Vortigern was greatly pleased with the success of his expedient. The Picts and Scots were driven back to their fastnesses in the remote mountains of the north, and the Britons once more possessed their land in peace, by means of the protection and the aid which their new confederates afforded them.
