New Attack of the Clones novel from 2002 found - LFL approved
They met before Dooku's sail ship, their lightsabers flashing and sparking in a violent dance. But after only a moment, it became clear who was the greater swordsman.
"Master Kenobi," Dooku said, "you disappoint me. Yoda holds you in such high esteem."
Obi-Wan caught his breath and attacked, momentarily driving the Count back. But Dooku quickly recovered and pressed his advantage. Obi-Wan found on the defensive. The lightsaber grazed his shoulder, then his thigh, drawing blood. Another blow struck Obi-Wan's lightsaber from his hand.
Dooku raised his lightsaber for the final blow, but as it fell, it was blocked - by Anakin!
Dooku staggered back, more surprised than hurt. The smile quickly returned to his face. "That's brave of you, boy. I would have thought you'd learn your lesson."
"I'm a slow learner."
Anakin charged again. The intensity of his attack caught Dooku off guard and he retreated.
Obi-Wan used the Force to summon his lightsaber and tossed it to Anakin. With two lightsabers, the young Jedi attacked anew. Bur Dooku blocked every thrust and, step by step, drove Anakin back. He slashed through one lightsaber, extinguishing its blade. Then, with a stroke faster than light, he cut through Anakin's right arm at the elbow.
The young Jedi dropped to the ground in agony, gripping the smoking stump of his sword arm.
As graceful as always, Count Dooku gathered himself for the death blow. But at that moment, the massive launch doors rumbled open, causing the Count to stagger backward.
Through the doors, trailed by billowing smoke, came Yoda.
"Count Dooku."
Dooku's lightsaber flashed in an elaborate salute. "Mastr Yoda, now we shall discover who is most powerful."
The Count flew across the space between them, his lightsaber raining blows on the small Jedi Master. Yoda did not give a centimeter. He stood beneath the storm, calmly deflecting blow after blow. As Dooku's fury increased, his strength failed, and his blows became less skillful.
Suddenly, Yoda attacked. His lightsaber was so fast that it seemed like a solid wall of light. Dooku cried out in amazement and stumbled.
"Powerful you have become," Yoda said. "I sense the dark side in you."
They crossed swords, and again Yoda mastered him easily.
"Fought well, you have, my old Padawan."
Count Dooku gasped for breath. "The battle is far from over. This is only the beginning."
Summoning the last of his strength, the Count reached out with the Force, toppling a huge crane onto Anakin and Obi-Wan. The two Jedi used the Force to atop its fall, and Yoda instantly lent his strength to theirs. The crane hovered, slid sideways in mid-air, and then crashed.
