Frode had by this taken his fleet over to Halogaland; and here, in order to learn the numbers of his host, which seemed to surpass all bounds and measure that could be counted, he ordered his soldiers to pile up a hill, one stone being cast upon the heap for each man. The enemy also pursued the same method of numbering their host, and the hills are still to be seen to convince the visitor. Here Frode joined battle with the Norwegians, and the day was bloody. At nightfall both sides determined to retreat. As daybreak drew near, Erik, who had come across the land, came up and advised the king to renew the battle. In this war the Danes suffered such slaughter that out of 3,000 ships only 170 are supposed to have survived. The Northmen, however, were exterminated in such a mighty massacre, that (so the story goes) there were not men left to till even a fifth of their villages. Frode, now triumphant, wished to renew peace among all nations, that he might ensure each man's property from the inroads of thieves and now ensure peace to his realms after war. So he hung one bracelet on a crag which is called Frode's Rock, and another in the district of Wik, after he had addressed the assembled Norwegians; threatening that these necklaces should serve to test the honesty which he had decreed, and threatening that if they were filched punishment should fall on all the governors of the district. And thus, sorely imperilling the officers, there was the gold unguarded, hanging up full in the parting of the roads, and the booty, so easy to plunder, a temptation to all covetous spirits. (a) Frode also enacted that seafarers should freely use oars wherever they found them; while to those who wished to cross a river he granted free use of the horse which they found nearest to the ford. He decreed that they must dismount from this horse when its fore feet only touched land and its hind feet were still washed by the waters. For he thought that services such as these should rather be accounted kindness than wrongdoing. Moreover, he ordained that whosoever durst try and make further use of the horse after he had crossed the river should be condemned to death. (b) He also ordered that no man should hold his house or his coffer under lock and key, or should keep anything guarded by bolts, promising that all losses should be made good threefold. Also, he appointed that it was lawful to claim as much of another man's food for provision as would suffice for a single supper. If anyone exceeded this measure in his takings, he was to be held guilty of theft. Now, a thief (so he enacted) was to be hung up with a sword passed through his sinews, with a wolf fastened by his side, so that the wicked man might look like the savage beast, both being punished alike. He also had the same penalty extended to accomplices in thefts. Here he passed seven most happy years of peace, begetting a son Alf and a daughter Eyfura.
