In the year 477 [q], Aella, a Saxon chief, brought over an army from Germany; and landing on the southern coast, proceeded to take possession of the neighbouring territory.

The Britons, now armed, did not tamely abandon their possessions; nor were they expelled, till defeated in many battles by their warlike invaders.

The most memorable action, mentioned by historians, is that of Meacredes Burn [r]; where, though the Saxons seem to have obtained the victory, they suffered so considerable a loss, as somewhat retarded the progress of their conquests.

But Aella, reinforced by fresh numbers of his countrymen, again took the field against the Britons, and laid siege to Andred-Ceaster, which was defended by the garrison and inhabitants with desperate valour [s].
The Saxons, enraged by this resistance, and by the fatigues and dangers which they had sustained, redoubled their efforts against the place, and when masters of it, put all their enemies to the sword without distinction.

This decisive advantage secured the conquests of Aella, who assumed the name of king, and extended his dominion over Sussex and a great part of Surrey.
