Jomsburg had been founded and built by King Harald Bluetooth of Denmark, who possessed a great earldom in Wendland. He had garrisoned the place with vikings on the condition that they should defend the land, and be always ready to support him in any warlike expedition.

There was a very fine harbour or dock made within the Burgh, in which three hundred longships could lie at the same time, all being locked within the strongly built walls of granite with their ma.s.sive gates of iron. The Jomsburg vikings were a well disciplined company of pirates who made war their exclusive business, living by rapine and plunder.

Their firm belief in the heathen G.o.ds justified them in following this mode of life, and often they fought for mere fighting's sake. They were bound by very strict laws to obey their chief. No man older than fifty or younger than eighteen winters could be received into the fellowship; they were all to be between these two ages. No man could join the band who was known to have ever yielded in fight to an opponent his match in strength of arms. Every member admitted swore by the hammer of Thor to revenge all the rest as his brother. Slander was forbidden. No woman or child was ever to be molested or carried away as captive, and all the spoil or plunder of war was to be equally divided. One very important law was that no member of the band was ever to utter a word of fear or to flinch from pain, or to attempt to dress his wounds until they had bled for four and twenty hours. Nothing could occur within the Burgh over which the chief should not have full power to rule as he liked. If any broke these rules he was to be punished by instant expulsion from the community.

For two days after the time when Olaf's fleet anch.o.r.ed abreast of the gates of Jomsburg, there was the work of inspecting all his men and ships and arms. Some two score of the men were rejected by Earl Sigvaldi, some because they were at enmity with certain vikings who were already of the band, others because they had killed some near kinsman of one of the members, and yet others who refused to follow or obey any other chief than Olaf Triggvison alone. But the ships and their equipment were all p.r.o.nounced seaworthy and in good condition; so, after the vows had been made, there was held a great feast, and Olaf was chosen as a captain under Earl Sigvaldi, holding the command of his own division of the Jomsburg fleet.

Now, during the summer months of that same year, Olaf went out upon a viking cruise into the Gulf of Bothnia. On the coast of Jemptland and Helsingialand he encountered many Swedish warships, cleared them, and slew many men, and took all the wealth of them. It was his habit to lie hidden behind some rocky promontory, or at the mouth of some vik, or creek, and thence dart out upon his unsuspecting prey; and he would thus creep along the coast from vik to vik, harrying and plundering wheresoever he went. And in all his battles he never received a wound or lost a ship, but always got the victory. He was accounted the most favoured by the G.o.ds among all the vikings of Jomsburg, and his renown spread far and wide.

When Olaf returned at the beginning of the winter to Jomsburg he heard that Earl Sigvaldi's father, Strut-Harald of Skaney, had just died. Now it was the custom in those days that a high born man, before he could take possession of any inheritance left to him by his father, should hold an arvel, or inheritance feast. King Sweyn was at this time preparing to hold such a feast before taking possession of the Danish kingdom, so it was arranged that Sweyn and Sigvaldi should make one arvel serve for them both, and Sweyn sent word to Sigvaldi inviting him with all his captains and chosen warriors to join him in Zealand, and so arrange it that the greatest possible honour should be done to the dead.

Sigvaldi accordingly left Jomsburg with a large host of his vikings and two score of ships. Among his captains were Olaf Triggvison, Kolbiorn Stallare, Bui the Thick of Borgund holm, Thorkel the High, and Vagn Akison. It was winter time, and the seas were rough, but the fleet pa.s.sed through the Danish islands without disaster, and came to an anchorage in a large bay near which now stands the city of Copenhagen.

King Sweyn welcomed Earl Sigvaldi and all his men with great kindness.

The feast was held in a very large hall, specially built for the reception of guests, and ornamented with splendid wood carvings and hung about with peace shields and curtains of beautiful tapestry. King Sweyn was dressed in very fine clothes of purple, with gold rings on his arms and round his neck, and a band of burnished gold, set with gems, upon his head. His beard, which was as yet but short, was trimmed in a peculiar way--divided into two p.r.o.ngs--which won for him the nickname of Sweyn Forkbeard. The tables were loaded with cooked food and white bread; sufficient to serve all the great company for three days. The ale and mead flowed abundantly, and there was much good cheer in the hall. Many high born women were present, and the guests sat in pairs, each man and woman together. Olaf Triggvison had for his partner the Princess Thyra, sister of the king.

In the midst of the feasting Thyra turned to Olaf and asked him his true name.

"Men call me Ole the Esthonian," answered Olaf.

"I had known so much already," returned Thyra. "It is the same name that you bore at the time we first met in Wendland. But when I look at you, and see your silken hair and your fair skin, it seems to me that you must be of kingly birth."

"It is not well always to judge by appearances," Olaf said with a smile. And he drew down the gold ring from the thick part of his bare left arm. Thyra's eyes rested upon his arm for a moment, and she saw imprinted there the seared brand that showed him to have been a slave; and from that moment she ceased to regard him with personal interest.

It was the custom at such feasts as this that the high seat, or throne, of the man whom the guests were met to do honour to, should be left vacant until the memorial toast of the deceased, and of the mightiest of their departed kinsmen, had been proposed. In accordance with this custom King Sweyn stood up and drank the cup of memory to his father.

Then he stepped into the high seat, and by this act took possession of his inheritance. The cup was filled and emptied to the last drop by each man in turn.

The Jomsburg vikings drank eagerly on that first evening, and ever as their drinking horns were emptied they were filled again, br.i.m.m.i.n.g of the strongest. After it had gone on thus for a while, King Sweyn saw that his guests were nearly all drunk.

"Here is great merriment," said he, rising and holding aloft his silver drinking horn. "And I propose that we shall find a new entertainment which will long hereafter be remembered."

Sigvaldi answered, "We think it most becoming and best for the entertainment, that you, lord, should make the first proposal, for we all have to obey you and follow your example."

Then the king laughed and said: "I know it has always been customary at great feasts and meetings that all present should make vows to perform great and valorous deeds, and I am willing to try that now. For, as you, Jomsvikings, are far more famous than all other men in this northern half of the world, so the vows you will make here will be as much more renowned than others, as you are greater than other men. And to set you an example, I will myself begin."

He filled his drinking horn to the brim and held it high, while all waited eagerly and silently to hear what vow he should make.

"This it is," said he in a loud voice which those at the farthest end of the hall could clearly hear. "I vow that I will, before the third winter nights hereafter have pa.s.sed, have driven King Ethelred of England out of his realm, or else have slain him, and thus have got his kingdom to myself!"

And so saying he quaffed his deep horn.

All wondered at this great vow, for not many had heard even the name of King Ethelred.

"Now it is thy turn, Sigvaldi," cried Sweyn, wiping his wet lips with the back of his hand, "and make no less a vow than mine."

Then the drink bearers bore to the vikings the biggest horns of the strongest drink that was there, and Sigvaldi rose to his feet. He first proposed the memory of his dead father, and before raising the drink to his lips added this oath:

"I swear," said he, "that before three winters are worn away I will sail over to Norway and slay Earl Hakon, or else drive him from the land."

Now, this was the selfsame oath that Olaf Triggvison had resolved to swear when it should come to his turn, and he was annoyed that Earl Sigvaldi had, as it were, s.n.a.t.c.hed it from his lips. He now thought over what other vow he could make in its stead. But it chanced that ere his turn came round all the company were either asleep or so full of strong drink that they could not listen, so in the end he made no vow whatsoever. Yet to the last he was as sober as when he first entered the hall, and he remembered ever afterwards the boastful oaths that had been made. Many of his fellow vikings--as Thorkel the High, Bui the Thick, and Vagn Akison--declared that they would but follow their chief to Norway, while others of Sweyn's following in like manner vowed to accompany the king to England; and once having made these promises, none dared to go back from them.

On the morrow, when the vikings regained their senses, they thought they had spoken big words enough, so they met and took counsel how they should bring about this expedition against Earl Hakon, and the end of it was that they determined to set about it as early as might be. For the rest of that wintertide the men of Jomsburg accordingly bestirred themselves in making preparations for the journey. They fitted out their best warships and loaded them with weapons, and their warriors were mustered to the number of eight thousand well trained men, with eighty chosen battleships.

So, when the snows of that winter had melted in the vales and the seas were clear of ice floes, Sigvaldi led his host north through the Eyr Sound and lay for a time in Lyme Firth. There he divided his forces, leaving twenty of Olaf Triggvison's longships in the firth, so that they might perchance intercept Earl Hakon should he escape the main fleet. This was an ill judged measure, but Sigvaldi was not aware that the forces of Earl Hakon were vastly superior in number to his own.

Olaf's ships were left in the charge of Kolbiorn Stallare, while Olaf himself went aboard the dragonship of Vagn Akison.

Earl Sigvaldi then sailed out into the main with sixty ships, and came to Agdir, in the south of Norway. And there he fell to pillaging in the dominion of Earl Hakon.

CHAPTER X: THE BATTLE OF JOMSVIKINGS.

The rumour of the bold vows that the Jomsvikings had made spread quickly throughout the land, and tidings of the great war gathering soon reached Norway. Earl Erik Hakonson heard them in good time at the place where he abode in Raum realm, and he straightway gathered his folk about him and fared to the Uplands, and so north over the fells to Thrandheim to meet Earl Hakon, his father. Now Earl Hakon greatly feared the vikings of Jomsburg, and on hearing this news he sent abroad the war arrow all about the Thrandheim country, and to Mere and Raumsdale, north also into Naumdale and Halogaland; and in answer to this summons there a.s.sembled a vast fleet of warships to the number of one hundred and eighty keels, and a force amounting to eleven thousand men. So many vessels and warriors had never before been seen together in the fiords.

Now there was a man named Giermund who was out sailing in a fishing skiff among the Her isles. He fared north to Mere, and there he fell in with Earl Hakon, and told the earl tidings of a host that had come to the land from Denmark.

"How can I know that what you tell is true?" asked the earl. "And what token have you to show?"

Giermund drew forth his right arm with the hand smitten off at the wrist.

"By this token may you know that these ships have come," said he.

Then Earl Hakon questioned the man closely concerning this new come enemy, and Giermund told him that the men were vikings of Jomsburg, and that they had slain many people of the land, and had robbed far and wide.

"Swiftly northward are they coming," said he, "and full eagerly, and no long time will wear by ere they are come upon you."

So thereupon the earl rowed through the firths with his fleet to meet his foes.

The Jomsvikings had sailed northward along the coast, plundering and ravaging wherever they landed. They made great coast raids, and often burned towns and hamlets. They were lying in Ulfasound, off Stad, when they and Hakon Jarl heard of each other. They were in want of food at this time, and Vagn Akison and Olaf Triggvison went on their skiff to the island of Hoed, not knowing that the earl lay in the bay near the island. Vagn and Olaf landed with their men, wishing to make a sh.o.r.e raid if they could, and they happened to meet a shepherd driving three cows and twelve goats.

Vagn cried to his men: "Take the cows and goats and slaughter them for our ships."

The shepherd asked: "Who commands the men on board your ship?"

"Vagn Akison, of Jomsburg," was the answer.

"I think then, that there are not very far from you bigger cattle for slaughter than my poor cows and goats," said the shepherd.

Vagn did not understand his meaning. But Olaf Triggvison looked at the man with quick apprehension, and said:

"If you know anything about the journey of Hakon Jarl, tell us at once.

And if you can truthfully tell us where he is, then your cows and goats are safe."

The shepherd did not speak for many moments, but at last he answered calmly: "Jarl Hakon lay yesternight with one or two ships under shelter of the island of Hoed, and you can slay him when you like, for he is still anch.o.r.ed in the bay waiting for his men."

"Then your cattle are safe," rejoined Vagn. "And you shall have a good reward if you will come aboard our ship and show us the way into the bay."

Ulf--for such was the shepherd's name--went on board the skiff early in the day, and Vagn Akison, as quickly as he could, returned to the Jomsburg fleet and told the news, which spread speedily round the ships. Earl Sigvaldi at once weighed anchor and rowed out north of the island, giving word meanwhile to his vikings to make ready for battle.
