But after this, when the Picts and Scots of the north
invaded the southern part of the island (or what we now call England),
the Britons in their alarm used to beg the assistance of the Romans
against them. And it would seem as if the British clergy had come to
depend on the help of others in much the same way; for when they found
what havoc the Pelagian Agricola was making among their people, they
sent over into Gaul, and begged that the bishops of that country would
send them aid against him.

Two bishops, German of Auxerre, and Lupus of Troyes, were sent
accordingly by a council to which the petition of the Britons had been
made. These two could speak a language which was near enough to the
British to be understood by the Britons; it was something like the
Welsh, or the Irish, or like the Gaelic, which is spoken in the
highlands of Scotland (for all these languages are much alike). Their
preaching had a great effect on the people, and their holy lives
preached still better than their sermons; they disputed with the
Pelagian teachers at Verulam, the town where St. Alban was martyred,[46]
and which now takes its name from him; and they succeeded for the time
in putting down the heresy.

It is said that while German and Lupus were in this country, the Picts
and Saxons joined in invading it; and that the Britons, finding their
army unfit to fight the enemy, sent to beg the assistance of the two
Gaulish bishops. So German and Lupus went to the British army, and
joined it just before Easter. A great number of the soldiers were
baptized at Easter, and German put himself at their head. The enemy came
on, expecting an easy victory, but the bishops thrice shouted
_Hallelujah!_ and all the army took up the shout, which was echoed from
the mountains again and again, so that the pagans were struck with
terror, and expected the mountains to fall on them. They threw down
their arms, and ran away, leaving a great quantity of spoil behind them,
and many of them rushed into a river, where they were drowned. The place
where this victory is said to have been gained is still pointed out in
Flintshire, and is known by a Welsh name, which means, "German's Field."
Pelagianism began to revive in Britain some years later, but St. German
came over a second time, and once more put it down.

But soon after this, the Saxons came into Britain. It is supposed that
Hengist and Horsa landed in Kent in the year 449
