It happened once in the Greek country, when Kirjalax was emperor there, that he made an expedition against Blokumannaland. When he came to the Pezina plains, a heathen king came against him with an innumerable host. He brought with him many horsemen, and many large waggons, in which were large loop-holes for shooting through. When they prepared for their night quarters they drew up their waggons, one by the side of the other, without their tents, and dug a great ditch without; and all which made a defence as strong as a castle.
The heathen king was blind. Now when the Greek king came, the heathens drew up their array on the plains before their waggon-fortification. The Greeks drew up their array opposite, and they rode on both sides to fight with each other; but it went on so ill and so unfortunately, that the Greeks were compelled to fly after suffering a great defeat, and the heathens gained a victory.
Then the king drew up an array of Franks and Flemings, who rode against the heathens, and fought with them; but it went with them as with the others, that many were killed, and all who escaped took to flight. Then the Greek king was greatly incensed at his men-at-arms; and they replied, that he should now take his wine-bags, the Varings. The king says that he would not throw away his jewels, and allow so few men, however bold they might be, to attack so vast an army.
Then Thorer Helsifig, who at that time was leader of the Varings replied to the king's words,
"If there was burning fire in the way, I and my people would run into it, if I knew the king's advantage required it."
Then the king replied,
"Call upon your holy King Olaf for help and strength."
The Varings, who were 450 men, made a vow with hand and word to build a church in Constantinople, at their own expense and with the aid of other good men, and have the church consecrated to the honour and glory of the holy King Olaf; and thereupon the Varings rushed into the plain. When the heathens saw them, they told their king that there was another troop of the Greek king's army come out upon the plain; but they were only a handful of people.
The king says,
"Who is that venerable man riding on a white horse at the head of the troop?"
"We do not see him."
There was so great a difference of numbers, that there were sixty heathens for every Christian man; but notwithstanding the Varings went boldly to the attack. As soon as they met terror and alarm seized the army of the heathens, and they instantly began to fly; but the Varings pursued, and soon killed a great number of them. When the Greeks and Franks who before had fled from the heathens saw this, they hastened to take part, and pursue the enemy with the others.
Then the Varings had reached the waggon- fortification, where the greatest defeat was given to the enemy. The heathen king was taken in the flight of his people, and the Varings brought him along with them; after which the Christians took the camp of the heathens, and their waggon-fortification.
