Hengist does not ever appear to have lost Thanet, and in the disorder after Vortigern’s death he was again able to invade Kent. In 457 he won a victory at Crayford, and the Britons retreated to the walls of London; yet in 465, and again in 473, the invaders are apparently still fighting in Kent. As the Jutish kingdom never extended far beyond the bounds of the modern county, there is every reason to believe that the conquest of Kent was a very slow and difficult process. Meanwhile, however, the successes of Hengist attracted the notice of his kinsfolk in Germany, and expeditions, not for purposes of plunder, but for permanent conquest, were being formed. The supposition must be put aside that England was founded as a number of separate states by independent bands of invaders. That the Britons made a stern resistance is beyond doubt, and to have been successful the invaders must have been acting in large and more or less organized bodies. Moreover, the invasions were national ones. Kent, indeed, possibly Sussex, may have been independent creations by chiefs of bodies of mixed mercenaries, but the whole English people (Angel-cynn) sooner or later took part in the settlement. It was a great national migration, and undoubtedly one of the most remarkable in history. The emigrants could not march by land, like the Goths and Franks, in great masses, which could bear down resistance by sheer weight of numbers and courage. They had to transfer themselves over hundreds of miles of sea in more or less frail open craft, at the mercy of every gale; yet in the course of a century the name of Angle had vanished from the Continent, and become peculiar to Britain. Possibly a remnant of the people remained behind; to this day a district of Schleswig bears the name of Angeln. Bede says that the invaders came from three nations of Germany, the Angles, Saxons, and Jutes. This appears to be so far true in that these three peoples took part in the migration; but while practically the entire English nation came, they were accompanied by only a few Saxons and a portion of the Jutes. It is very probable, also, that fragments of nearly all the Teutonic tribes on the Continent were in the invading hosts. The kingdom of Kent is said to have been Jutish; certainly its social structure differed remarkably from that of the other English states, but Hengist himself seems to have been an Angle. Bede says that the Kentish Code was written in the _English_ language. The confused grammatical structure of the present English tongue certainly points to a mingling of races, and on the whole we may infer that the invasion was conducted not only by the Angles, but by many kindred tribes, and that these latter in course of time gradually came to regard themselves as English also. Early mediæval writers use the terms ‘Angle’ and ‘Saxon’ indiscriminately.
