Toranaga's ronin-samurai charged. An arrow smashed a man in the chest and he fell heavily. Instantly the Brown on the forepoop killed the Gray archer and tried for the other but this samurai was too quick and they locked swords, the Gray shouting a warning of treachery to the others. The Brown on the aft quarterdeck had maimed one of the Grays but the other three dispatched him quickly and they raced for the head of the gangway, seamen scattering. The samurai on the dock below were fighting to the death, the Grays overwhelming the four Browns, knowing that they had been betrayed and that, at any moment, they too would be engulfed by the attackers. The leader of the Grays on deck, a large tough grizzle-bearded man, confronted Blackthorne and Mariko.
"Kill the traitors!" he bellowed, and with a battle cry, he charged.
Blackthorne had seen them all look down at Mariko, still lying in her faint, murder in their eyes, and he knew that if he did not get help soon they were both dead, and that help would not be forthcoming from the seamen. He remembered that only samurai may fight samurai.
He slid his knife into his hand and hurled it in an arc. It took the samurai in the throat. The other two Grays lunged for Blackthorne, killing swords high. He held the second knife and stood his ground over Mariko, knowing that he dare not leave her unprotected. From the corner of his eye he saw the battle for the gangway was almost won. Only three Grays still held the bridge below, only these three kept help from flooding aboard. If he could stay alive for less than a minute he was safe and she was safe. Kill 'em, kill the bastards!
He felt, more than saw, the sword slashing for his throat and leaped backward out of its way. One Gray stabbed after him, the other halted over Mariko, sword raised. At that instant Blackthorne saw Mariko come to life. She threw herself into the unsuspecting samurai's legs, crashing him to the deck. Then, scrambling across to the dead Gray, she grabbed the sword out of his still twitching hand and leaped on the guard with a cry. The Gray had regained his feet, and, howling with rage, he came at her. She backed and slashed bravely but Blackthorne knew she was lost, the man too strong. Somehow Blackthorne avoided another death thrust from his own foe and kicked him away and threw his knife at Mariko's assailant. It struck the man in the back, causing his blow to go wild, and then Blackthorne found himself on the quarterdeck, helplessly at bay, one Gray bounding up the steps after him, the other, who had just won the forepoop fight, racing toward him along the deck. He jumped for the gunwale and the safety of the sea but slipped on the blood-wet deck.
Mariko was staring up, white-faced, at the huge samurai who still had her cornered, swaying on his feet, his life ebbing fast but not fast enough. She hacked at him with all her force but he parried the blow, held her sword, and tore it out of her grasp. He gathered his ultimate strength, and lunged as the ronin-samurai burst up the gangway, over the dead Grays. One pounced on Mariko's assailant, another fired an arrow at the quarterdeck.
The arrow ripped into the Gray's back, smashing him off balance, and his sword sliced past Blackthorne into the gunwale. Blackthorne tried to scramble away but the man caught him, brought him crashing to the deck, and clawed for his eyes. Another arrow hit the second Gray in the shoulder and he dropped his sword, screaming with pain and rage, tearing futilely at the shaft. A third arrow twisted him around. Blood surged out of his mouth, and, choking, his eyes staring, he groped for Blackthorne and fell on him as the last Gray arrived for the kill, a short stabbing knife in his hands. He hacked downward, Blackthorne helpless, but a friendly hand caught the knife arm, then the enemy head had vanished from the neck, a fountain of blood spraying upwards. Both corpses were pulled off Blackthorne and he was hauled to his feet. Wiping the blood off his face, he dimly saw that Mariko was stretched out on the deck, ronin-samurai milling around her. He shook off his helpers and stumbled toward her, but his knees gave out and he collapsed.
It took Blackthorne a good ten minutes to regain enough strength to stand unaided. In that time the ronin-samurai had dispatched the badly wounded and had cast all corpses into the sea. The six Browns had perished, and all the Grays. They had cleansed the ship and made her ready for instant departure, sent seamen to their oars and stationed others by the stanchions, waiting to slip the mooring ropes. All flares had been doused. A few samurai had been sent to scout north along the shore to intercept Buntaro. The bulk of Toranaga's men hurried southward to a stone breakwater about two hundred paces away, where they took up a strong defensive position against the hundred Grays from the frigate who, having seen the attack, were approaching fast.
