The massive head swung from side to side and the eyes glowed greenly. He did not growl or bark. Silently as a phantom he slid in behind them.
"Let him come," muttered Conan. "He can smell the devils before we can see them."
Balthus smiled and laid his hand caressingly on the dog's head. The lips involuntarily writhed back to display the gleaming fangs; then the great beast bent his head sheepishly, and his tall moved with jerky uncertainty, as if the owner had almost forgotten the emotions of friendliness. Balthus mentally compared the great gaunt hard body with the fat sleek hounds tumbling vociferously over one another in his father's kennel yard. He sighed. The frontier was no less hard for beasts than for men. This dog had almost forgotten the meaning of kindness and friendliness.
Slasher glided ahead, and Conan let him take the lead. The last tinge of dusk faded into stark darkness. The miles fell away under their steady feet. Slasher seemed voiceless. Suddenly he halted, tense, ears lifted. An instant later the men heard it—a demoniac yelling up the river ahead of them, faint as a whisper.
Conan swore like a madman.
"They've attacked the fort! We're too late! Come on!"
He increased his pace, trusting to the dog to smell out ambushes ahead. In a flood of tense excitement Balthus forgot his hunger and weariness. The yells grew louder as they advanced, and above the devilish screaming they could hear the deep shouts of the soldiers. Just as Balthus began to fear they would run into the savages who seemed to be howling just ahead of them, Conan swung away from the river in a wide semicircle that carried them to a low rise from which they could look over the forest. They saw the fort, lighted with torches thrust over the parapets on long poles. These cast a flickering, uncertain light over the clearing, and in that light they saw throngs of naked, painted figures along the fringe of the clearing. The river swarmed with canoes. The Picts had the fort completely surrounded.
An incessant hail of arrows rained against the stockade from the woods and the river. The deep twanging of the bowstrings rose above the howling. Yelling like wolves, several hundred naked warriors with axes in their hands ran from under the trees and raced toward the eastern gate. They were within a hundred and fifty yards of their objective when a withering blast of arrows from the wall littered the ground with corpses and sent the survivors fleeing back to the trees. The men in the canoes rushed their boats toward the river- wall, and were met by another shower of clothyard shafts and a volley from the small ballistae mounted on towers on that side of the stockade. Stones and logs whirled through the air and splintered and sank half a dozen canoes, killing their occupants, and the other boats drew back out of range. A deep roar of triumph rose from the walls of the fort, answered by bestial howling from all quarters.
"Shall we try to break through?" asked Balthus, trembling with eagerness.
Conan shook his head. He stood with his arms folded, his head slightly bent, a somber and brooding figure.
"The fort's doomed. The Picts are blood-mad, and won't stop until they're all killed. And there are too many of them for the men in the fort to kill. We couldn't break through, and if we did, we could do nothing but die with Valannus."
"There's nothing we can do but save our own hides, then?"
"Yes. We've got to warn the settlers. Do you know why the Picts are not trying to burn the fort with fire-arrows? Because they don't want a flame that might warn the people to the east. They plan to stamp out the fort, and then sweep east before anyone knows of its fall. They may cross Thunder River and take Velitrium before the people know what's happened. At least they'll destroy every living thing between the fort and Thunder River.
"We've failed to warn the fort, and I see now it would have done no good if we had succeeded. The fort's too poorly manned. A few more charges and the Picts will be over the walls and breaking down the gates. But we can start the settlers toward Velitrium. Come on! We're outside the circle the Picts have thrown around the fort. We'll keep clear of it."
They swung out in a wide arc, hearing the rising and falling of the volume of the yells, marking each charge and repulse. The men in the fort were holding their own; but the shrieks of the Picts did not diminish in savagery. They vibrated with a timbre that held assurance of ultimate victory.
Before Balthus realized they were close to it, they broke into the road leading east.
"Now run!" grunted Conan. Balthus set his teeth. It was nineteen miles to Velitrium, a good five to Scalp Creek beyond which began the settlements. It seemed to the Aquilonian that they had been fighting and running for centuries. But the nervous excitement that rioted through his blood stimulated him to herculean efforts.
Slasher ran ahead of them, his head to the ground, snarling low, the first sound they had heard from him.
"Picts ahead of us!" snarled Conan, dropping to one knee and scanning the ground in the starlight. He shook his head, baffled. "I can't tell how many. Probably only a small party. Some that couldn't wait to take the fort. They've gone ahead to butcher the settlers in their beds! Come on!"
Ahead of them presently they saw a small blaze through the trees, and, heard a wild and ferocious chanting. The trail bent there, and leaving it, they cut across the bend, through the thickets. A few moments later they were looking on a hideous sight. An ox-wain stood in the road piled with meager household furnishings; it was burning; the oxen lay near with their throats cut. A man and a woman lay in the road, stripped and mutilated. Five Picts were dancing about them with fantastic leaps and bounds, waving bloody axes; one of them brandished the woman's red-smeared gown.
At the sight a red haze swam before Balthus. Lifting his bow he lined the prancing figure, black against the fire, and loosed. The slayer leaped convulsively and fell dead with the arrow through his heart. Then the two white men and the dog were upon the startled survivors. Conan was animated merely by his fighting spirit and an old, old racial hate, but Balthus was afire with wrath.
He met the first Pict to oppose him with a ferocious swipe that split the painted skull, and sprang over his failing body to grapple with the others. But Conan had already killed one of the two he had chosen, and the leap of the Aquilonian was a second late. The warrior was down with the long sword through him even as Balthus' ax was lifted. Turning toward the remaining Pict, Balthus saw Slasher rise from his victim, his great jaws dripping blood.
Balthus said nothing as he looked down at the pitiful forms in the road beside the burning wain. Both were young, the woman little more than a girl. By some whim of chance the Picts had left her face unmarred, and even in the agonies of an awful death it was beautiful. But her soft young body had been hideously slashed with many knives—a mist clouded Balthus' eyes and he swallowed chokingly. The tragedy momentarily overcame him. He felt like falling upon the ground and weeping and biting the earth.
"Some young couple just hitting out on their own," Conan was saying as he wiped his sword unemotionally. "On their way to the fort when the Picts met them. Maybe the boy was going to enter the service; maybe take up land on the river. Well, that's what will happen to every man, woman, and child this side of Thunder River if we don't get them into Velitrium in a hurry."
Balthus' knees trembled as he followed Conan. But there was no hint of weakness in the long easy stride of the Cimmerian. There was a kinship between him and the great gaunt brute that glided beside him. Slasher no longer growled with his head to the trail. The way was clear before them. The yelling on the river came faintly to them, but Balthus believed the fort was still holding. Conan halted suddenly, with an oath.
He showed Balthus a trail that led north from the road. It was an old trail, partly grown with new young growth, and this growth had recently been broken down. Balthus realized this fact more by feel than sight, though Conan seemed to see like a cat in the dark. The Cimmerian showed him where broad wagon tracks turned off the main trail, deeply indented in the forest mold.
"Settlers going to the licks after salt," he grunted. "They're at the edges of the marsh, about nine miles from here. Blast it! They'll be cut off and butchered to a man! Listen! One
