With a ship-load of priests Haakon departed from this fateful meeting with the Danish king. But no sooner was he out of Harold's sight, than he put his priests ashore, and began to harry on both sides of the Sound. On the rocky cliffs of Gautland he made a grand sacrificial feast, to counteract the effect of his recent baptism, and stood watching for a response from the old gods, that they looked upon him with favor, and would give him success in the war he was about to undertake. Then two ravens came and followed his ships, "clucking" loudly. The ravens were the birds of Odin, and Haakon saw in their flight a happy augury. A warlike fury seems now to have possessed him. With a recklessness which in so prudent a man is inconceivable (except under high religious excitement), he burned his ships, landed with his army on the coast of Sweden, and marched northward, ravaging the land with fire and sword. A broad track of blood and desolation followed his destructive progress. Even in the Norwegian province Viken, which Harold Bluetooth had given to Sweyn Forkbeard, he continued his devastations in pure wantonness, as if to advertise his defiance of the Danish king and all that belonged to him. From Viken he took his way overland to Drontheim, where he henceforth lived as an independent sovereign; though for some reason he refrained from assuming the royal title. It was probably some time before Harold Bluetooth could raise an army strong enough to pursue the earl and defeat him in his own stronghold. There is some doubt, however, whether his campaign to Norway, for the purpose of punishing his rebellious vassal, took place in 976 or two or three years later. Following Haakon's example, he laid the land waste, killing and burning every thing in his path. In Laerdal in Sogn, he left only five houses unburned. When, however, Earl Haakon sailed southward to meet him with a numerous fleet, the king suddenly lost his courage, set sail, and made for home. It is said that Harold Bluetooth had on that occasion no less than twelve hundred ships.
