When the next Yuletide sacrifice came Haakon was required to eat horse-flesh at the feast and this time was forbidden to make the sign of the cross when he drank the usual toasts to the ancient gods of Norway. This was a humiliation that cut the proud monarch deeply and it was with an angry soul he left, saying to his attendants that when he came back it would be with an army to punish those who had thus insulted his faith. Back he did not come, for new troubles were gathering around him. To learn the source of these troubles we must return to the story of Erik Blood-Axe and Gunhild, his wicked wife. After Erik's death that mischief-loving woman sought Denmark with her sons, who grew up to become brave warriors and daring viking rovers, infesting the coast of Norway and giving its king and earls all the trouble they could. At length, backed by Harold Bluetooth, the king of Denmark, their piratical raids changed to open war, and they invaded Norway, hoping to win their father's old kingdom for themselves. A crisis came in 955. In that year the sons of Erik appeared so suddenly with a large fleet that they took King Haakon by surprise. He had with him only a small force, the signal fires had not been lighted, and the enemy were close at hand before he could prepare to meet them. "What shall we do?" he asked his men. "Shall we stay and fight, or draw back and gather men?" The answer came from an old peasant, Egil Woolsack: "Often have I fought, King Haakon, with King Harold, your father. Whether the foe was stronger or weaker the victory was always his. Never did he ask his friends if he should run; nor need you, for we are ready to fight and think that we have a brave chieftain for our leader." "You speak well and wisely, Egil," said the king. "It is not my wish to run, and with your aid I am ready to face the foe." "Good words those!" cried Egil joyously. "It has been so long since I saw the flash of sword that I feared I would die in my bed of old age, though it has been my hope to fall in battle at my chieftain's back. Now will my wish be gained." To land came the sons of Erik, having six men to Haakon's one. Seeing how great were the odds, old Egil tried strategy, leading ten standard-bearers to a hidden spot in the rear of the hostile army and leaving them there in ambush. When the armies had met and the fighting was under way, he led these men up a sloping hill until the tops of their standards could be seen above its summit. He had placed them far apart, so that when the Danes saw the waving banners it looked like a long line of new troops coming upon them. With sudden alarm and a cry of terror they fled towards their ships.
