Knife upon hemp cutteth silently, but soon the sentinel turned with a sharp exclamation, for out of the seaward silence there came a long, vibrating whistle, another, another, and then from the hollow of a dark wave near the trireme there sounded a fourth like unto these three. This last he answered with a shout, and he hurled his pilum at that darkness in the water, but the trireme herself responded with a lurch and a yawing as she began to be swept away by the tide. There were rowers on board, and they quickly sprang to the oars, but they were few and there was yet no steersman. There were many soldiers also, but their officer ordered a number of them to the oars, that he might get the ship under control. When, therefore, there came gliding swiftly out of the shadows the unlooked-for warship of the Saxons she was alongside and her grapplings were made fast with none to hinder.
From the opposite side of the Roman vessel, as it were from the water itself, now sounded furiously the war horn of Biorn the Berserker. Full half of the legionaries rushed in that direction and their hurled spears were too hastily lost in the sea. Terribly rang out the war horns and the battle shouts of the Saxons, but the first man of them on board of the trireme was Ulric the Jarl, and down before his ax fell whoever met him. Close behind him were his followers, so that the nearer Romans were not only surprised, but outnumbered.
Up the side, near the stern, climbed Biorn the Berserker, and for a moment he was alone, so quickly had fallen twain who were there. Taking in hand the helm, "Biorn! Biorn the Berserker!" he shouted. "O jarl, I am here! The ship is ours!" Hard fought the remaining Romans, nevertheless, against such odds, but all the rowers were slain at their oars.
"It is done!" said Ulric. "Silence, all! I have called twice for Biorn. Where is he?"
"O jarl, son of Brander the Brave!" came faintly back from the after deck, "hast thou fully taken this trireme?"
"We have her!" answered Ulric. "Thanks to thee, O Biorn! She is thine!"
"Odin!" shouted back the old berserker. "Then bear thou witness for me, at feast and in song, that Biorn, the son of Nar, the sea king, died not by drowning, but by the driven spear of a Roman, in all honor. I go to Valhalla as becometh me. Rejoice, therefore, and smite thou these Romans once more for me. I die!"
There was a silence of a moment on the ship, but then the oldest viking of all blew triumphantly his horn and shouted: "We have heard! Biorn, the hero, hath gone to the hall of the heroes. He died by the spear, and not a cow's death. Good is his fortune. Hael to thee, O Biorn! And hael to Jarl Ulric, the leader of men."
Clashed loudly then the shields and spears, but already Saxon hands were upon the oars and Tostig the Red was at the helm, with Olaf by him. Only it might be a dozen warriors had been named by the valkyrias to go to Valhalla with Biorn the Berserker, but the Romans whose bodies were cast into the sea were ten times as many.
The Sword and the trireme were now going out with the tide into the open sea and into the darkness, but there had been much sounding of trumpets in the camp of the Romans. Few as were the remaining legionaries, they had marched to the shore ready for action. There were small boats at the beach, but it was all too late for any use of these. Those who patrolled and inquired, however, found at the side of a rock a helmet like a bear's head, a shirt the hide of a bear, two heavy spears, an ax—the trophies to them of Biorn the Berserker. These were brought to the centurion in command and he examined them with care.
