Olaf, and the Northmen's fleet with him, rowed quite up under the
bridge, laid their cables around the piles which supported it,
and then rowed off with all the ships as hard as they could down
the stream. The piles were thus shaken in the bottom, and were
loosened under the bridge. Now as the armed troops stood thick

stones and other weapons upon it, and the piles under it being
loosened and broken, the bridge gave way; and a great part of the
men upon it fell into the river, and all the ethers fled, some
into the castle, some into Southwark. Thereafter Southwark was
stormed and taken. Now when the people in the castle saw that
the river Thames was mastered, and that they could not hinder the
passage of ships up into the country, they became afraid,
surrendered the tower, and took Ethelred to be their king. So
