period of ascendency could be measured only by the continuance of the
danger.

From Bede's writings we find that the Scots from the west and the Picts
from the north continually harassed the Britons despite occasional help
from Rome, and despite the wall they built across the north of England. In
these straits the British invited help from the Angles and Saxons, who
soon engaged the northern tribesmen and defeated them. The feebleness of
the Britons having become well known among the continental peoples, the
Angles, Saxons and Jutes began to steadily swarm across the North Sea in
powerful, armed bands. Having for a time assisted the Britons they began
to seek excuses for quarrels, and gradually the Britons with brief periods
of success were beaten and dispossessed of their lands until they were
driven into the western parts of the island. The Angles occupied most of
northern England, including the kingdom of Northumbria, of which Yorkshire
formed a large part. These fierce Anglo-Saxon people, with an intermixing
of Danish blood, a few centuries later were the ancestors of a great part
of the present population of the county. Sidonius Apollinaris, a Bishop of
Gaul, who wrote in the fifth century, says, "We have not a more cruel and
more dangerous enemy than the Saxons: they overcome all who have the
courage to oppose them; they surprise all who are so imprudent as not to
