Acting with the sanction of Odo, whom he deeply revered, the young
Edgar, then only in his fifteenth year, accepted the offer, and the
whole force of Mercia was gathering to support him when Edwy crossed the
border.

It must not be supposed that either Cynewulf or Redwald expected to
conquer the Mercians with ten thousand men. No, their design was
simpler: they had learned where Edgar was residing, and that the forces
around him were small. One bold stroke might secure his person, and then
Edwy might make his own terms. This was the secret of the advice they
both gave to the young king.

Redwald had, as we shall see, deep designs of his own to serve also, but
they had been locked for years in his own breast, and no servant could
seem more trusty and faithful than he did, or act with more energy in
his master's cause.

The forces of Edwy, as we have related, left St. Alban's on the second
morning, and travelled, horse and foot, very rapidly all that day.

Crossing the Icknield Street at Dunstable, where the remains of a huge
temple, once sacred to Diana, were visible, they entered Mercia, and
soon reached Towcester, a town which had been walled round by King
Athelstane; here they found no force prepared to receive them, and the
town opened its gates at once.

They tarried here for a day, while they sent scouts and spies in all
directions, many of whom never returned. The troops were quartered
freely upon the inhabitants, who were evidently very hostile; and, in
return, the soldiers of Edwy insulted the women and bullied the men.
Every hour some quarrel arose, and generally ended in bloodshed; the
citizens being commonly the victims.

Late at night messengers arrived at the royal quarters, bringing
information that Edgar was at Alcester, the ancient Alauna, beyond the
Avon, and that Osric, the great Earl of Mercia, was with him collecting
troops.

A council was held at once, and it was decided to leave the Watling
Street and to march for the Avon by cross-country routes. They rested
that night amidst the ruins of the ancient Brinavae, and here another
council was held, to deliberate on their future movements, and it was
decided to march westward at once, for tidings came that Edgar's forces
were rapidly increasing, and prudence suggested prompt measures. Edwy
was becoming very anxious.

The route for the next day was then made out and, with beating heart,
Elfric learned that they purposed crossing the river
