They were missing only two men when they regrouped by the waiting light squadrons. Arn observed the great confusion that prevailed in that part of the army which had seemed to him invincible. Almost a hundred Hospitaller knights had now been killed or wounded. What he saw was impossible, and his mind stood still for a moment. If the Forsvikers with a single attack had vanquished so many Hospitaller knights, it was a miracle from God. But he didn’t believe that God would smite His own most faithful fighters with such a punishment, nor did he believe that God was constantly intervening in the petty struggles of humanity here on earth.

The Danes had employed a stratagem of war, he realized. They had falsely dressed themselves in red surcoats with a white cross so they would look like Hospitallers and thus sent fear into the hearts of the enemy. And they had almost succeeded.

Without a word Arn left his bloody lance with the closest man, took his confanonierBirger Magnusson with him, and rode down towards the Danes. He stopped an arrow-shot away and held up both hands in the sign that he wanted to parley. At once six men dressed in red and white rode up to him.

At first he addressed them politely in Frankish, of which they understood not a word. Then he switched to their own language and asked that the two bodies they had left behind be delivered to them, since they were dear kinsmen who had fallen. The Danes replied that this could not be done without something in return. Arn said that for his part he considered that honour demanded that both sides conduct such business without gain. Then the Danes relented. He asked them about their clothing, and they explained that it had been given to them by God during a crusade in the east, and that the white cross on the red field was now the emblem of the kingdom of Denmark.

At Gestilren there were several high hills, and there Arn had positioned both his heavy cavalry and his longbowmen, since he didn’t believe it would work again to keep all his longbows at the same place; few Danes would ride into that trap for a second time. Down on the plain stood the entire Folkung heavy cavalry under the leadership of Folke jarl and Magnus Månesköld, and behind them all the crossbowmen, who in turn blocked the way of the already impatient Swedes. Farthest back stood five hundred Norwegian archers that Harald Øysteinsson had brought from his home region.

It was an absurd arrangement with everyone standing in everyone else’s way. But as if by God’s Providence it was now close to dusk, and the battle would have to wait until the next day. They had the night before them to alter things, in the event it was possible to make the Swedes and the stubborn high-born kinsmen understand that the positioning of the troops in the new type of warfare was more important than courage in the breast.

It was a long night with much argument and troublesome moving about in the dark. But the next morning at dawn, as the Danish army began to be visible through the mist, they were at least better arrayed than the night before.

Arn sat on his horse next to King Erik atop the highest hill along with the entire heavy section of the Forsviker cavalry and two squadrons of light cavalry to protect the king or remove him from danger. For Arn and his heavy riders there was only one task. They had to kill Sverker Karlsson.

Sune Folkesson, who was the one person in the world who most wanted to take the life of the former King Sverker, had requested to ride heavy and next to Arn, who was his master and teacher. Arn could not refuse him this request; he had attempted to put together this group containing only the best and the eldest of the Forsvikers.

From up on their hill they could look out over the entire battlefield. If the Danes sent off their cavalry toward the Eastern Goths and the Swedish foot-soldiers, this time they would have the black clouds of arrows from the longbows falling on them from each side. The Eastern Goths themselves would not attack before they saw a blue flag raised from the king’s position. That was what they had finally agreed on.

The battle looked to be starting well. The Danes had discovered that this time too they were superior in the number of heavy horsemen. If they could break through the lines of the Eastern Goths, they would have a clear field to mow down all the foot-soldiers from Svealand.

The temptation was too much for them, and they made ready to attack in just that manner. Arn bowed his head and thanked God.

But when the Danes came in their attack, Folke jarl and Magnus Månesköld did not wait for the blue signal from up on the king’s hill, but went on the attack themselves. So the first wave of Folkungs rode into the same rain of arrows as the enemy. The middle of the battlefield was transformed in a few moments to a mass of the dying and wounded. Then the Swedes could hold back no longer but began running toward the battle so that they arrived gasping and worn out. From up on his hill Arn and King Erik watched powerlessly as everything was about to slip out of their hands. There was a moment of salvation from Harald Øysteinsson and his Norwegians, who on the other side of the valley began to run up the line of battle to get into position so that they would be sure that their arrows fell only among the Danes.

The entire Forsviker light cavalry stood outside the battle, because the plan had been for them to attack to the rear of the Danes. But there they had a much too large and concerted force against them, since the Danish army had not advanced far enough into the trap. Arn sent riders to bring the Forsvikers as quickly as possible to the middle of the battle with the command to attack at will.

Everything was about to be lost. For in a protracted, unorganized battle, the side with the most men would win. Arn said farewell to King Erik, left Birger Magnusson with the double Folkung and Erik flag on the hill with the king, and led all his heavy cavalry in a wide arc upwards and back.

They reached a position where they could see where Sverker Karlsson and his massed standards were located, at a safe distance from the battle itself. There was no longer any reason to wait, and any hesitation would only serve to allow the enemy more time to prepare.

They rode out of the woods in disarray, but quickly fell into formation in a line as they trotted forward toward the heart of the enemy. They sped up to a full gallop and lowered their lances when they had only a few breaths left before they engaged. Next to Arn rode Sune Folkesson; they had both spied Sverker Karlsson’s emblem, the black griffin with the golden crown, and headed straight for it.

The Forsvikers smashed straight through the first lines of Sverker’s defenders, but by then most had lost both their speed and their lance, or had broken it and had to draw their swords or war hammers and start hacking their way toward Sverker. They made slower and slower progress, and several of them fell on the way.

But it was too late to turn back. Arn fought his way forward in a frenzy, discovering that his sword had grown heavier in recent years. Then he flung away his shield, shifted his sword to his left hand, and pulled out his long war hammer with his right. He killed four men with his war hammer and two with his sword before he reached Sverker. At the same time Sverker was parrying blows from Sune Folkesson, thus exposing the back of his neck to Arn, who swiftly slew him with his war hammer.

As Sverker fell from his horse there was a sudden silence among the Danes and Sverkers who were still in the saddle. The battle ceased, and everyone looked around. Half of all the Forsvikers had fallen, but still they were more numerous than the Danes, who were slowly rallying around Archbishop Valerius and his emblem.
