From Vermeland, where his enterprise began, he led his forlorn seventy southward toward Viken, his party rolling on like a snowball and growing in size on its way, until it swelled to four hundred and twenty men. In spite of his protest, these vagabonds proclaimed him king and touched his sword to indicate their allegiance. But their devotion to his cause was not great, for when he forbade them to rob and plunder the peasants most of them left him. To test the remainder, he ordered them back to Vermeland and before they reached that region only the original seventy remained.
Desperate was now the position of the youthful adventurer. He had declared himself a claimant for the throne and any one had the right to kill him. The peasants hated his robber band and he could get none to join him. They would rather have killed them all and thus earned the king's favor.
Had young Sverre been a man of common mind his enterprise must now have reached its end. But he was a man of wonderful mental resources, daring, indefatigable, capable of bearing the most extreme reverses and rescuing himself from the most perilous situations. Followed by his faithful seventy, he wandered through the pathless mountain wilderness, hopeful and resourceful. His courage was unfailing. Often they had to live on bark and frozen berries, which were dug up from under the snow. At times some of his men, worn out with hunger and exposure, would drop lifeless on their barren paths; at times he had to sleep under his shield, as his only protection from the falling snow; but his heart kept stout through it all, and he chided those who talked of ending their misfortunes by suicide.
As an example of his courage and endurance and his care of his men, we may tell the following anecdote. Once in his wanderings he came to a large mountain lake which had to be crossed. It could only be done on rafts, and the men were so exhausted that it proved desperate work to fell trees and build the necessary rafts. In time they were all despatched, Sverre boarding the last, which was so heavily laden that the water rose above his ankles.
One man was still on the shore, so utterly worn out that he had to crawl to the water's edge and beg to be taken on, lest he should perish. The others grumbled, but Sverre would not listen to their complaints but bade them to take the man on. With his extra weight the raft sank till the water reached their knees. Though the raft threatened to go to the bottom Sverre kept a resolute face. A great fallen pine on the other side made a bridge up which the men clambered to safety, Sverre being the last to leave the raft. Scarcely had he done so when the watersoaked logs sank. The men looked on this as a miracle and believed more fully than ever that he would win.
Now came the first success in his marvellous career. He had one hundred and twenty men on reaching the goal of his terrible journey, but here eighty men more joined him and with these two hundred followers he successfully faced a force of fourteen hundred which had been sent against him. With a native genius for warfare he baffled his enemies at every point, avoiding their onset, falling upon them at unexpected points, forcing them to scatter into separate detachments in the pursuit, then falling on and beating these detachments in succession. While he kept aware of their plans and movements, they never knew where to look for him, and in a short time the peasant army was beaten and dispersed.
This striking success gave new courage and hope to the Birchlegs and they came in numbers to the place to which Sverre had summoned a body of twelve representatives from the province of Tröndelag. These met and proclaimed him king of Norway. It was now the summer of 1177.
The Birchlegs were hasty in supposing the beating of fourteen hundred peasants would bring success to their cause. Erling Skakke was still alive and active, and on hearing of the exploits of this new leader of rebels in the north, he got together a large fleet and sailed northward to deal with him.
The new-proclaimed king was too wary to meet this powerful force and he sought refuge in the mountains again, leaving to Erling the dominion of the coast. And now, for two years, Sverre and his men led a precarious life, wandering hither and thither through the mountain wilderness and suffering the severest privations. He was like a Robin Hood of the Norwegian mountains, loving to play practical jokes on the peasants, such as appearing with his hungry horde at their Yuletide feasts and making way with the good cheer they had provided for themselves. He was obliged to forage in the valleys, but he took pity on the poor and more than once made the great suffer for acts of oppression.
Everywhere he was hated as a desperate brigand; some believed him to be the devil himself. Naughty children were scared with the threat that the terrible Sverre would take them, and laundresses, beating their clothes at the river's brink, devoutly wished that Sverre's head was under the stone. Yet his undaunted resolution, his fights with the king's soldiers, his skirmishes with the peasants, and his boldness and daring in all situations, won him a degree of admiration even among those who feared and hated him.
