Cormac waited in a silence that had become suddenly tense. Then without warning the night was shattered by one fearful death-yell! Pandemonium broke loose and a mad hell of sound burst on the air. And now the forest came to life! From all sides stocky figures broke cover and swarmed on the barricades. A lurid glare shed a ghastly light over all and Cormac tore savagely at his chains, wild with excitement. Monstrous events were occurring without, and here he was, chained like a sheep for the slaughter! He cursed incredibly.
The Norsemen were holding the wall; the clash of steel rose deafeningly in the night, the hum of arrows filled the air, and the deep fierce shouts of the Vikings vied with the hellish wolf-howling of the Picts. Cormac could not see, but he sensed the surging of human waves against the stockade, the plying of spears and axes, the reeling retreat and the renewed onset. The Picts, he knew, were without mail and indifferently armed. It was very possible that the limited force of Vikings could hold the stockade until Thorwald returned with the rest, as he would assuredly do when he saw the. flame-but whence came the flame?
Someone was fumbling at the door. It swung open and Cormac saw the lean shambling frame and livid bearded face of Grimm Snorri's son limned against the red glare. In one hand he held a helmet and a sword Cormac recognized as his own, in the other a bunch of keys which jangled as his hand shook.
"We are all dead men!" squawked the old Viking, "I warned Thorwald! The woods are alive with Picts! There are thousands of them! We can never hold the stockade until Thorwald returns! He is doomed too, for the Picts will cut him off when he comes into the bay and feather his men with arrows before they can come to grips! They have swum around the outer horns of the stockade and set the three remaining galleys on fire! Osric would run like a fool with a dozen carles to save the ships and he had scarcely gotten outside the gates before he was down with a score of black shafts through him and his men were cut off and hemmed in by a hundred howling demons! Not a man of them escaped, and we barely had time to shut the gates when the whole screaming mob was battering at them!
"We have slain them by the scores, but for every one that drops, three spring to take his place. I have seen more Picts tonight than I knew were on Golara-or in the world. Cormac, you are a bold man; you have a ship somewhere off the isle-swear to save me and I will set you free! Mayhap the Picts will not harm you-that devil Brulla did not name you in his death rune.
"If any man can save me it is you! I will show you where Hrut is hidden and we'll take him with us-" he threw a quick glance over his shoulder toward the roar of battle beachward, and went white. "Thor's blood!" he screamed, "The gates have given way and the Picts are inside the inner, stockade!"
The howling rose to a crescendo of demoniac passion and fiendish exultation.
"Loose me, you gibbering fool!" raged Cormac, tearing at his chains. "You've time enough for babbling when-"
Chattering with fear, Grimm Snorri's son stepped inside the hut, fumbling with the keys-even as his foot crossed the threshold a lean shape raced swift and silent as a wolf out of the flame-shot shadows. A dark arm hooked about the old Viking's withered neck, jerking his chin up. One fearful shriek burst from his writhing lips to break short in a ghastly gurgle as a keen edge whipped across his leathery throat.
Over the twitching corpse of his victim, the Pict eyed Cormac Mac Art, and the Gael stared back, expecting death, but unafraid. Then in the glare of the burning ships, that made the cell-hut as light as day, Cormac saw that the slayer was the chief, Brulla.
"You are he who slew Aslaf and Hordi. I watched through the door of the skalli before I dragged myself away to the forests," said the Pict, as calmly as though no inferno of combat was raging without, "I told my people of you and warned them not to harm you, if you still lived. You hate Thorwald as well as I. I will free you; glut your vengeance; soon will Thorwald return in his ships and we will cut his throat. There shall be no more Norse or Golara. All the free people of the isles here-abouts are gathering to aid us, and Thorwald is doomed!"
He bent over the Gael and released him. Cormac sprang erect, a fresh fire of confidence surging through his veins. He snatched his helmet with its flowing horsehair crest, and his long straight sword. He also took the keys from Brulla.
"Know you where was prisoned the Dane called Hrut?" he asked, as they stepped through the door. Brulla pointed across a seething whirlpool of flame and hacking swords.
"The smoke obscures the hut at present, but it lies next the storehouse on that side."
Cormac nodded and set off at a run. Where Brulla went he neither knew nor cared. The Picts had fired stable, storehouse and skalli, as well as the ships on the beach outside the inner stockade. About the skalli and here and there close to the stockade which was also burning in a score of places, stubborn fighting went on, as the handful of survivors sold their lives with all the desperate ferocity of their breed. There were, indeed, thousands of the short, dark men, who swarmed about each tall blond warrior in a slashing, hammering mass. The heavy swords of the mailed Vikings took fearful toll, but the smaller men lashed in with a wild beast frenzy that made naught of wounds, and pulled down their giant foes by sheet weight of numbers. Once on the ground, the stabbing swords of the dark men did their work. Screams of death and yells of fury rent the flame-reddened skies, but as Cormac ran swiftly toward the storehouse, he heard no pleas for mercy. Driven to madness by countless outrages, the Picts were glutting their vengeance to the uttermost, and the Norse people neither looked nor asked for mercy.
Blond-haired women, cursing and spitting in the faces of their killers, felt the knife jerked across their white throats, and Norse babes were butchered with no more compunction than their sires had shown in the slaughter-for sport-of Pictish infants.
Cormac took no part in this holocaust. None of these people was his friend-either race would cut his throat if the chance arose. As he ran he used his sword merely to parry chance cuts that fell on him from Pict and Norseman alike, and so swiftly he moved between staggering clumps of gasping, slashing men, that he ran his way across the open space without serious opposition. He reached the hut and a few seconds' work with the lock opened the heavy door. He had not come too soon; sparks from the burning storehouse nearby had caught on the hut thatch and already the interior was full of smoke. Through this Cormac groped his way toward a figure he could barely make out in the corner. There was a jangling of chains and a voice with a Danish accent spoke: "Slay me, in the name of Loki; better a sword thrust than this accursed smoke!"
Cormac knelt and fumbled at his chains. "I come to free you, oh Hrut," he gasped. A moment later he dragged the astonished warrior to his feet and together they staggered out of the hut, just as the roof fell in. Drawing in great draughts of air, Cormac turned and stared curiously at his companion-a splendid, red maned giant of a man, with the bearing of a noble. He was half-naked, ragged and unkempt from weeks of captivity, but his eyes gleamed with an unconquerable light.
"A sword!" he cried, those eyes blazing as they swept the scene, "A sword, good sir, in the name of Thor! Here is a goodly brawl and we stand idle!"
Cormac stooped and tore a reddened blade from the stiffening hand of an arrow-feathered Norseman.
"Here is a sword, Hrut," he growled, "but for whom will you strike the Norse who have kept you cooped like a caged wolf and would have slain you-or the Picts who will cut your throat because of the color of your hair?"
"There can be but little choice," answered the Dane, "I heard the screams of women-"
