I really should do my assignment.
But eh.
Update!
"This eternal war is...UNLIMITED BLADE WORKS!"
And the sky burned.
Saber roared with laughter. "Good, good, very good, young mage! Perhaps you are not as useless of a Master as I first thought? Now, show me the power of your soul!"
One, then four, then nine, then an endless cloud of swords rose into the air, surrounding Shirou. He raised his arm, and three swords spun to point towards Saber, steel edges glinting under the red sky. "The power of my soul...is in these swords!" Shirou whipped his arm towards Saber, and the three blades flew towards Saber, homing unerringly towards his heart.
Saber was already moving. As the three swords stabbed harmlessly into the ground where he had stood a minute earlier, he looked up to see Shirou hot on his heels, with two swords in his hands and five more in the air. "Do you think to fight me sword to sword, young mage? Then you are a greater fool then that imbecile Jason! I am Saber, strongest of the Seven!"
"Who said I would use my own strength?" Shirou asked, and even as Saber brought up his guard, Shirou hurled one sword, then the next, then the five following him, one after the other.
"If you think that your attack will work again-" but Saber never finished. Seven massive explosions in succession sounded, and a ball of fire covered him. As the smoke cleared and Saber stumbled out, arm nearly severed, an eighth sword sliced cleanly into his chest and detonated.
'Two down, ten to go. Damn it Archer, where are you?' Shirou wondered, as he sprinted across the rust-red ground. An earth-shaking bellow of rage sounded from somewhere behind him, and he cursed. He was out of time.
"DIE!" Saber thundered as he bore down on Shirou, gigantic sword swinging down towards his head...
"Shirou, do you understand why you lost?" Archer asked, as they both sat overlooking a Shogi board.
"I don't know. I kept the principle of war you were talking about, mass, in mind at all times."
"And that was correct. However, there is more to the art of war then simple numbers. Given the correct circumstances, a smaller, elite force can inflict devastating damage to a larger one."
"How so? Wouldn't the larger force simply be able to surround the smaller one and attack from all sides?"
"Correct. Hence why I mentioned circumstances. What sort of circumstances do you think would prevent a larger force from doing exactly as you said?"
"Well...it would be somewhere that emphasizes the advantage of the smaller force, so...the front would have to be small, because one for one, the smaller force is superior."
"Excellent, Shirou. You are learning well. Where would such circumstances occur?"
"A canyon."
"Explain."
"Because the canyon mouth is small and restricted, only a fraction of the larger force can fight at any time, while the smaller force can fight all at once, increasing their effectiveness."
"Precisely. Now, a real-life example, or case study as we called it back in Sandhurst..." Archer drifted off for a moment. "excuse me. A real-life example occurred in 480 BC..."
Shirou raised his arm as if to ward off the blow, and Saber's mighty swing smashed into a row of bronze shields. They shattered, they splintered...but they held, and Shirou was already preparing more swords.
Who wants to guess the NP Shirou pulled out?
