Urging his rowers to their fullest speed, Erik bore down with his ships upon the extreme of King Olaf's right wing. The heavy, iron bound bow of the Ram crashed into the broadside of Olaf's outermost longship, whose timber creaked and groaned under the impact. Vikings and berserks leapt down upon her decks, and now Norseman met Norseman in a terrible, deadly combat. The king's men were well nigh exhausted with the long day's fighting under the hot sun; their bronzed faces streamed with perspiration, their limbs moved wearily. But, however, tired and thirsty they were, they could give themselves no respite. Every man that fell or was disabled by wounds left a gap in the ranks that could not be filled. The earl's men were fresh and vigorous; they had waited for hours for their chief's orders to enter the fray, and now that those orders had been given to them they fought with hot fury, yelling their battle cries and cutting down their foemen with ponderous axe and keen edged sword.
So fierce was the onslaught that many of Olaf's men, for the first time that day, fell back in fear and clambered over the bulwarks of the next ship. Very soon the decks of the first longship were completely cleared of defenders. Then Earl Erik backed out with the Iron Ram, while the seamen on his other ships cut away the lashings that had bound Olaf's outermost vessel to her neighbour, and drew the conquered craft away into the rear, leaving the next ship exposed.
Again Earl Erik advanced with the Ram and crashed as before into the exposed broadside of the outermost ship. As before, the vikings leapt on board and renewed the onset. Five of the viking ships lay with their high prows overshadowing the broadside bulwarks, and their men swarmed and clamoured upon the decks from stem to stern, clearing all before them. Again the lashings were cut and the conquered longship was withdrawn.
Two of King Olaf's dragons had now been captured by Earl Erik. It was not very long ere yet two others followed; and then the Short Serpent was exposed, even as her four companions had been. At this juncture Earl Erik paused, for he saw that Thorkel Nefja's decks were densely crowded with men who had retreated from vessel to vessel before the onslaught of the vikings. With the caution which long years of viking work had taught him, the earl decided that the Short Serpent might best be assailed by means of arrows, fired from a safe distance, until her numbers had been sufficiently diminished to warrant his attacking her at closer quarters. So he arrayed six of his ships near hand and set his archers to work, and for a long while this method of assault was continued.
There was no lack of arrows on the Short Serpent, or indeed, on any other of King Olaf's battleships. But it was noticed by the earl's vikings that the larger number of the shafts that were shot at them by the defenders were of Danish or Swedish make, and by this it was judged that the king's men were using the arrows that had been fired upon them by their enemies.
Leaving his six ships where he had stationed them, Earl Erik now rowed the Iron Ram round to the left wing of Olaf Triggvison's array. Four of his best longships followed him. He passed astern of the king's fleet. As he rowed by under the poop of the Long Serpent he saw the majestic figure of the King of Norway, looking brilliant in gold and scarlet as he stood in flood of the afternoon sunlight, sword in hand and shield at breast. The eyes of the two bravest of Norse warriors met. Waving his sword in mock salute, Earl Erik cried aloud:
"Short will be Olaf's shrift when Erik boards the Long Serpent!"
King Olaf saw that near to where Erik stood, on the Iron Ram's forward deck, the image of the god Thor was raised, and he cried aloud in answer:
"Never shall Erik board the Serpent while Thor dwells in his stem!"
"A wise soothsayer is the king," said Earl Erik to one of his warriors as he passed onward astern of the Crane. "And I have been thinking, ever since this battle began that the great luck of Olaf may be due to that sign of the cross that we see on all his banners and shields. Often have I felt a wish to turn Christian, for it seems to me that all Christian men have something noble and honest about them--a greatness which we heathens can never achieve. Now do I swear upon the hilt of my sword"--he raised his sword hilt to his lips--"that if I win this battle and take the Long Serpent for my prize I will straightway allow myself to be christened. And, to begin with, I will have that image of Thor thrown overboard into the sea. It is ill made and cumbrous, and a figure of the cross will take less room in our stem and bring us more luck withal."
