Since ancient times: Of southern talent north will, shaanxi loess buries the emperor. Archaic north area, as a result of with nomadic having vast border on region, a lot of war from this and unripe. In frequent flames of war, also made archaic north area form full-bodied Biao Han's martial wind, the brave that can sign war of be used to theres is no lack of era person. Period of the Three Kingdoms, mere Shanxi area, gave a lot of shake temporarily general. For instance the Guan Yu of the first of all of 5 tigers admiral, it is person of Shanxi carry city. The Zhang Liao with Cao Wei Wuzi will medium fine, it is person of city of Shanxi new moon, xu shakes is Shanxi Hong Dongren.
In the battle of next Pi of initial stage of the Three Kingdoms, liu has little power of one party power loses, by Cao Cao checkmate, guan Yu also is held by Cao in hassle capture. What Cao holds Guan Yu of take pity on is valiant, cannot bear do harm to, guard a pass then feather stay in Cao Ying, want to let him die for oneself. In the time that Guan Yu spends in Cao Ying, with fellow-townsman Zhang Liao and Xu shake personal feeling agree with each other, the knot issues a paragraph of friendship. Unfortunate is, their friendship fails to last how long, because each are its advocate, they part company finally, each goes his own way.
After this, they are themselves all the time advocate fair effectiveness battlefield, seek a range rarely. But hill does not turn water turns, in proposing a when install 24 years big fight, guan Yu and Xu shake to meet once more, just meet this, it is on battlefield war meets. The of first Guan Yu of 5 tigers admiral, be defeated this to shake at hand in Xu however, have a reason among them. The word says in those days July, guan Yu of general of the kingdom of Shu Han dispatchs troops from Jing Zhou, the Kingdom of Wei of northern expedition Cao, to Cao Wei pilot assists Fan Yi belt launchs storm. Guan Yu is in this battle, achieved him the summit summit condition of army brigade career, capture at banning behead Pang heart, water wides 7 army power shake an ancient name for China, and surround fencing city of town of military importance heavily, in a short while can be defeated.
Cao Cao became confused hands or feet, assemble hastily fall south forces resist Guan Yu. General Xu shakes dying to recieve orders, guide a forces to be driven toward fencing city front. Because just be completely annihilated at the army that stand, this go out for a battle, the military strength have too many problems to deal with that Xu shakes, " annals of the Three Kingdoms " account, "Shake a will much Xin Cu, with feather difficult with contend for sharp edge " . Brash between, the at hand that Xu shakes is a batch just the recruit that recruit comes to, fighting capacity and Guan Yu's picked Jing Zhoujun differs very far. Cao Cao is afraid very, enjoin Xu to shake repeatedly: "Part of beard military forces comes, before be all " , after the big unit that waits for him to assemble subsequently arrives, again with Guan Yu battle.
Xu shakes advanced line and Guan Yu insecurity to confront each other, cao Cao is in rear also do not have at a loose end, transfer from each district on one hand military strength, counterpoise actively with Jiang Dongsun on one hand contact, want to make Guan Yu of his harassing attack rear, in order to alleviate pressure of Cao army front. Sun Quan's letter in reply came very quickly, " annals of the Three Kingdoms " account, sun Quan says in the letter, take by surprise dispatchs troops to involve a rear Jiang Ling public security on his horse two town of military importance, to moment Guan Yu is sure to answer division to save oneself, of Fan Cheng surround can solve oneself. He enjoins Cao Cao repeatedly in the letter: "Beg does not leak closely, ling Yu has equipment " , let Cao Cao notice to keep secret, do not let Guan Yu learn, lest he shifts to an earlier date,guard against.
Cao Cao is worthy of is generation a person who achieves high position by unscrupulous scheming, in the heart after he reads a letter easily, had an idea. He summons minister people, consultative this letter is this make public or keep secret. " annals of the Three Kingdoms " account, adviser Dong Zhao thinks, this letter should be open. Dong Zhao says: "Exquisite adaptability in tactics of resort to arms is convenient. Might as well divulge this letter intentionally go out. Guan Yu hears Sun Quan wants harassing attack his rear, inevitable meeting withdraws troops and take a hold rear, of Fan Cheng surround can remove ahead of schedule. Come so, but two tigers photograph fights Guan Yu of authority of grandson of sit by and watch, we bide our time and move. We bide our time and move..
Dong Zhao says again: "If do not publish this letter, make Sun Quan not needing the slightest effort white get two city, not be the best thing to do. In together with fencing city Cao Wei Shoujun, now already popular feeling in a state of anxiety, precarious, once morale breaks down, fan Cheng inevitable fall " . Cao Cao listens, had said repeatedly. He commands instantly, regard as this letter " secret weapon " the Xu that presents front shakes, "Shoot with power book surround in in reaching a village " , let he believes Sun Quan this excerption a few, in shooting Fan Cheng with bow, in the battalion camp with Guan Yu.
Cao Cao delivers this " secret weapon " as expected the effect is extraordinary, surpass 1000 army 10 thousand horses. The Cao Jun in Fan Cheng is defended will, in Guan Yu onslaught servent person highs oneself, arms without fight, a lot of people had abandoned hoping, fall into enemy hands possibly at any time. And the arrival of this letter, let be overjoyed of fencing city Cao Jun, sun Quan is about to atttack Guan Yu rear, guan Yu will be removed very quickly army, made them new see triumphal hope. " annals of the Three Kingdoms " account, "Surround li of Wen Zhi, ambition hundredfold " , risk one's life strikes back Guan Yu is attacked, make difficulty of Guan Yu that attack a town increases greatly.
And after Guan Yu sees this seals a letter, more amazed not small. Temporarily between, he also decides hard, the deceptive forces that this is Cao Cao after all plan, what Sun Quan can atttack him after all is rear. If be former, he should ignore, continue onslaught fencing city. But if be latter, he must matter urgent withdraw troops, by night answers aid rear base, was carried by Sunquan otherwise the den can not play. Result, a letter lets valiant and decisive Guan Yu, in be immersed in the corner that be in a dilemma, overcautious and indecisive, indecisive, " annals of the Three Kingdoms " account, "Feather hesitate if really " . His at hand officerses and men also the heart does not have fight, be in because of their dependant belongings rear.
The strategics composing of Wu Qi of home of main forces thing " Wu Zibing law " in, mention technically: "The calamity of resort to arms, hesitation is the biggest, the calamity of the army, be born at doubt " . Use at appearance right now dangerous place of Guan Yu, it may be said is again appropriate nevertheless. A letter let Guan Yu eat to have a deficit greatly, 100 battle powerful army of Guan Yu from now on fight is devoid. In the encounter that shakes to Xu next, guan Yu advance and retreat is broken according to, be distracted, as if condition is absent like changing an individual, because this ability can be shaken to beat by Xu, and from this cannot recover after a setback, till be defeated,die.
