he power of his father, Leofric, he obliged Harold to submit to an
accommodation, and was reinstated in the government of East Anglia.
This peace was not of long duration: Harold, taking advantage of
Leofric's death, which happened soon after, expelled Algar anew, and
banished him the kingdom; and though that nobleman made a fresh
irruption into East Anglia with an army of Norwegians, and overran the
country, his death soon freed Harold from the pretensions of so
dangerous a rival. Edward, the eldest son of Algar, was indeed
advanced to the government of Mercia; but the balance which the king
desired to establish between those potent families was wholly lost,
and the influence of Harold greatly preponderated.

[MN 1055.] The death of Siward, Duke of Northumberland, made the way
still more open to the ambition of that nobleman. Siward, besides his
other merits, had acquired honour to England by his successful conduct
in the only foreign enterprise undertaken during the reign of Edward.
Duncan, King of Scotland, was a prince of a gentle disposition, but
possessed not the genius requisite for governing a country so
turbulent, and so much infested by the intrigues and animosities of
the great Macbeth, a powerful nobleman, and nearly allied to the
crown, not content with curbing the king's authority, carried still
farther his pestilent ambition; he put his sovereign to death; chased
Malcolm Kenmore, his son and heir, into England; and usurped the
crown. Siward, whose daughter was married to Duncan, embraced, by
Edward's orders, the protection of this distressed family: he marched
an army into Scotland; and having defeated and killed Macbeth in
battle, he restored Malcolm to the throne of his ancestors [q]. This
service, added to his former connexions with the royal family of
Scotland, brought a great accession to the authority of Siward in the
north; but as he had lost his eldest son, Osberne, in the action with
Macbeth, it proved in the issue fatal to his family. His second son,
Walthoef, appeared, on his father's death, too young to be intrusted
with the government of Northumberland; and Harold's influence obtained
that dukedom for his own brother Tosti.

There are two circumstances related of Siward, which discover his high
sense of honour, and his m
