"Guide me to the river and the marsh," he said to Wulf the Skater.
"I will, O jarl," said Wulf; "but Tostig saw a wild boar yesterday and he hath gone out after him. A vast one, he sayeth, with tusks like a walrus. He will fight well if they can bring him to a fighting."
"Let Tostig win his boar," said Ulric. "We go to the left and we hunt not. I am full of thoughts about this place."
A score of vikings were with them, and they marched on in order, two and two, as if they had an errand. Grand were the trees, and high, with branches whose foliage made a gloom to walk in.
"Are we nearly at the marsh?" asked Ulric at last. "Here are rocks."
"I know not, O jarl," said Wulf. "We came not so far southerly yesterday."
"Hael, Northmen! Hael! But sound no horn! Who are ye?"
As if he had suddenly arisen through the ledge of rocks before them, upon it stood a tall shape in full armor, spear in hand. From under his helmet tangled white hair fell down to his shoulders, but his right hand, holding the spear, was lifted as by one who giveth a command.
Again he spoke: "I am Olaf, the son of Hakon, of Droningsfiord. Who are ye?"
"Northmen of thine own land," said the jarl. "I am Ulric, the son of Brander. Our ship, The Sword, lieth at the shore. How camest thou where thou art, and who is with thee?"
"None are with me," said Olaf, sternly. "We were many, but the Romans have smitten the Saxon shore of Britain and our villages are gone. They have smitten many of the Britons also, and they march to smite them again this day. Tell me, O Jarl Ulric, hast thou seen aught of certain triremes which were to come? I would know if there are more Romans near than I have already counted."
"One hath perished, as I will shortly tell thee," said Ulric. "I have seen no other."
"Good!" said Olaf. "There floateth one in a harbor not far away, but they who came in her are fewer than when they landed. Twain came, with a cohort. One hath sailed. Their force was sent to slaughter the Druids at their great sacrificing, but first they struck our village at our harbor. We fought, but they were too many. I cut my way through the ranks of their lighter spearmen, and they followed me not far because of the nearness of the Britons."
Olaf was now descended from the rock and was become as one of them. Great was his wonder at the story of the living sand and the trireme.
"The gods of the Britons are strong at times," he said, "but they are not to be depended on. They have done this because of the great sacrifice, that the Romans may not hinder it. Therefore come thou with me a little distance and I will show thee a matter. The Romans are tangled in a wood. Meddle not thou and thine, however, for thou hast another work to do."
"I meddle not," said the jarl, "but I thank these Druid gods. We were closely pushed and in peril when they ensnared the trireme with their sand. I will offend them not, but I would see these great sacrifices and I also would offer my token."
"That the Druids will forbid thee," said Olaf. "Follow me quickly to the crown of this ridge, for it is on the bank of the river."
Even as he spoke there came to their ears a clangor of trumpets, as if many sounded at once.
"Romans!" exclaimed Ulric.
"Sounding first were they," said Olaf, "but these hoarse ones, very loud, are blown by the Druids. Hear, also, the harping. Now look thou, for thou art a captain."
The river before them was but narrow, although it might be deep, and on the other side was a broad open space surrounded by a forest with dense undergrowths of bushes, as if it were marshy. In the open was arrayed a cohort of Roman soldiers, well ordered, but beyond and in their front might be seen and heard much larger numbers of such as they were, all disarrayed and scattered by the copses. None assailed the cohort in the open, but all the forest swarmed with half-armed Britons, hurling darts and plying their light blades. Arrows, also, were flying, and there was a great tumult of mingled sound.
"The men in white robes, keeping afar," said Olaf, "are the Druid priests. This is as an ambush, and the Romans are falling."
"Their commander hath some wisdom, I think," said Ulric. "His trumpets call back his men for a retreat. He will escape."
"He loseth half his force," said Olaf; "he will lose more as he retreateth."
Fiercer and fiercer arose the sounds of the combat, the shouting, the howling, the twanging of loud harp strings, and the braying of the trumpets. Hard was it for the vikings that they might not have a part in such a battle.
"The Romans are outnumbered," said Olaf, "but they fight well. Their retreat will be to the river mouth, where was my village. There have they a camp in our own stockade, and they have also increased it with a rampart of earth and palisades. There we must strike them. It is but a little distance. Come and see."
"But first," said Ulric, "I would see the end of this battle, and I would have speech with a Druid concerning the sacrifices."
"That thou mayest not this day," said Olaf, "and the Romans are cutting their way through the tumult of half-naked spearmen. Lo, how they slay the Britons! But the ranks of their cohort will be thin when the remnant reacheth the fort. So hath it often been in their warfare in Britain, but each new commander of legionaries cometh here a proud one, thinking only of easy victory."
"The darts fly in showers," said Ulric, but Wulf the Skater urged him.
"O jarl!" he exclaimed. "The village! The fort! The trireme! Why wait we here? Let us go with Olaf!"
The jarl answered not, but walked rapidly, and the rocky ledge grew higher as they went; but there came an end of it.
"We have walked far," said Ulric. "The way of the Romans was shorter. There come they and their array is not broken. I can see their commander ordering them."
"Thor the Thunderer!" exclaimed Olaf, "what havoc the Britons have made among them! The gods of the Druids have protected their sacrifices."
"Every Roman left behind hath perished," said Ulric. "Only these are alive."
"Not so," said Olaf. "Not a wounded man or one entrapped hath been slain. He belongeth to the gods at the place of sacrifice."
"With them as with us," said the jarl. "That is the old North custom. I have seen men slain at the stone of Odin. He who is captured must lose his head. It is well – "
"Seest thou?" loudly demanded Olaf. "The ruins of our village are yet smoking, although three days have passed. I saw thy ship on the sea yesterday, but knew not of thy landing. I meant to watch for thee or for the coming triremes after seeing the battle."
"Yonder trireme at anchor," replied the jarl, "floateth well out from the river mouth. She is large. How shall I take her? For there are yet Romans enough to hold her well. I must come to her by night in The Sword."
Long and thoughtfully gazed Ulric, studying the position of the trireme and the arrival of the beaten Romans at the fort.
"O jarl," said Biorn the Berserker, "knowest thou not that I am a fish? The trireme is held but by an anchor and a cord of hemp. Go thou and bring The Sword. When thou art at hand to strike thou mayest have the trireme drifting with the outgoing tide. Strike not when the tide runneth in?
"Thou canst swim," said Ulric, "and thy seax will sever hemp; but if thou waitest here until I come, how wilt thou know in the dark of my coming, or how wilt thou know where to ply the sharp edge?"
"When I hear thee whistle thrice," said Biorn, "as if thou wert calling thy hawk, I will know of thy coming. If the whistle is from this shore, I meet thee here. If it is from seaward, I swim to the trireme. Thou wilt know the hemp is severed when thou hearest my own falcon call."
"I go with thee, O jarl!" shouted Olaf, eagerly, "that I may be thy pilot."
"Well for thee, O Biorn the Berserker," said Ulric; "thou art of the heroes!"
"Here sit I down," replied Biorn. "It is a pleasant place. I think this taking of the trireme will depend upon thee and thy sword more than upon a man a fish cutting hemp!"
"Haste, now," said Ulric to his men. "The Sword is far from us and this is to be a night of great deeds, and not of ale and feasting."
Olaf led, as the guide of their rapid marching, and Biorn sat down upon a rock to gaze at the doings around the river mouth and at the fort.
"There come the Britons out of the woods," he said to himself. "If they had been well led they would have pursued more closely – only that few care to press too hard upon even the wreck of a Roman army. Now are all the Romans within the stockade."
The Britons were many, but their prey had escaped them. The camp fort was too strong for them to storm, and their showers of darts flew over the palisades without much harm to any within. The taunting clangor of their harps and trumpets sounded furiously for a while, and then the multitude swiftly vanished as if it had melted away.
"If these Britons had a captain," said Biorn, "instead of a herd of priests, and if he would arm them well, the Romans would disappear from Britain. But I think Ulric the Jarl will find many swords on yonder trireme. Even now they go out in small boats. Biorn the Berserker will be with him when the Saxons are on the Roman deck!"
