Then they went on fighting expeditions in the summer, remaining in the
Barra Isles during the winter.

CHAPTER IV. FIGHT WITH VIKINGS VIGBJOD AND VESTMAR

There were two Vikings from the Southern Isles, named Vigbjod and
Vestmar; they were abroad both summer and winter. They had eight ships,
and harried mostly round the coast of Ireland, where they did many an
evil deed until Eyvind undertook the defence of the coast, when they
retired to the Hebrides to harry there, and right in to the Scotch
firths. Thrand and Onund went out against them and learned that they had
sailed to an island called Bot. Onund and Thrand followed them thither
with five ships, and when the vikings sighted them and saw how many
there were, they thought their own force was sufficient, so they took to
their arms and advanced to the attack. Onund ordered his ships to
take up a position between two rocks where there was a deep but narrow
channel, open to attack from one side only, and by not more than five

"Trolls take the rascal Treefoot
and lay him even with the ground.

Never yet did I see men go to battle who could not carry themselves."

Onund said that could not be known until it was tried. Then the ships
came together. There was a great battle in which both sides fought
bravely. When the battle was thick Onund ordered his ships to back their
oars. The vikings seeing it thought they were taking to flight, and
pushed on with all their might, coming under the rock just at the moment
when the party which had been dispatched for that purpose arrived. They
launched upon the vikings stones so huge that nothing could hold against
them. A number of the vikings were killed, and others were so injured
that they could fight no more. Then the vikings tried to escape, but
could not, as their ships were i
