声东击西

 
shēng dōng jī xī (sheng dong ji xi)
clamor in the east, then strike in the west (get an opponent to gather strength in one location then strike in another)

In any battle the element of surprise can provide an overwhelming advantage. Even when face to face with an enemy, surprise can still be employed by attacking where he least expects it. To do this you must create an expectation in the enemy's mind through the use of a feint.

Song Dynasty China

Once there was an official who was transferred to the capital. The front part of the inn where he stayed was a teahouse, and across the street was a shop that sold expensive dyed silks. Whenever he had nothing to do, he would sit at a table watching the people and activity on the street. One day he noticed with surprise that several suspicious looking characters were walking back and forth observing the silk shop with great interest. One of them came up to his table and whispered: "We're in the robbery business and we're here to steal those fine silks. Since you noticed us I came to ask you not to mention it."

"That has nothing to do with me," the official replied. "Why should I say anything about it?"

The fellow thanked him and left him. The official thought to himself: 'the silk shop has its wares openly displayed on a busy street. In broad daylight, with a thousand eyes watching, if they have the skill to steal those silks, then they must be smart thieves indeed.' So he watched carefully to see how they would manage it. But what he saw was only the same people walking back and forth in front of the silk shop. Sometimes they gathered on the left, sometimes on the right. The official sat watching until after sunset when everyone had gone and the shop had closed. "Those fools." said the official to himself. "They were putting one over on me." When he returned to his room to order some food, he discovered that all his belongings were gone.

Cao Cao

In AD 200, Yuan Shao and Cao Cao fought a decisive battle. Yuan Shao, with the advantage of terrain and troop strength, wanted to block the enemy's route of retreat (Battle of Guandu).
Yuan Shao ordered general Yan Liang to lead 10,000 soldiers to occupy the enemy's strategic Baima city.
Cao Cao was told of the enemy's plan. He summoned his aides to help think of a solution. One of his aides, Xun You said, "Let's show as if we're crossing the river to attack Ye city. Yuan Shao will send some troops westwards. In the meantime, we can surround Baima and attack the remaining Yuan Shao troops."
Falling for the ruse, Yuan Shao led some troops to reinforce Ye city. Yan Liang surrounded Baima and believing that Cao Cao's army was attacking Yanjin and Ye, thought that Cao Cao will surrender in a few days time. Meanwhile, Cao Cao made his troops travel day and night to Baima.
Yuan Shao reached Yanjin and found nobody there. Cao Cao managed to kill Yan Liang and thus the siege was lifted.

Napoleon

In 1798, Napoleon Bonaparte had planned an invasion of Egypt. But in order for his ground troops to be transported into Egypt, he would have to get through the powerful British Navy. Napoleon decided to avoid a direct confrontation during the transportation, since a defeat here would cost many lives. Napoleon informed his Mediterranean fleet that they were to join up with the fleet in the north, and attack Ireland. As a result of this news, Horatio Nelson stationed his fleet in the west of the Mediterranean, in order to block the French fleet from moving up north. Napoleon then quickly ordered his Mediterranean fleet to transport ground troops into Egypt. By the time Horatio discovered Napoleon 's plans, about 3 weeks had passed and a large French army had gathered in Egypt. Although the French Mediterranean fleet was eventually destroyed in the Battle of the Nile, Napoleon was able to conquer Egypt with his ground troops.

Gulf War

In the 1991 Gulf War the coalition through Military deception was able to convince the Iraqis that the coalition intended an amphibious attack into Kuwait and was able to fix Iraqi forces in positions that could play no effective part when the real attack came.

Meaning: 声:声张。指造成要攻打东边的声势,实际上却攻打西边。是使对方产生错觉以出奇制胜的一种战术。

Context: 《淮南子·兵略训》:“故用兵之道,示之以柔而迎之以刚,示之以弱而乘之以强,为之以歙而应之以张,将欲西而示之以东,……”唐·杜佑《通典·兵六》说:“声言击东,其实击西。”

Example: 蜀人或~,指南攻北,吾兵必须分头守把。 ◎明·罗贯中《三国演义》第一百十一回

Synonyms: 出其不意、出奇制胜

Grammar: 联合式;作谓语、宾语、定语;用于军事等

敌志乱萃①,不虞②,坤下兑上 ③之象,利其不自主而取之。

【注释】

①敌志乱萃:援引《易经.萃》卦中《象》辞:“乃乱乃萃,其志乱也”之意。萃,悴,即憔悴。是说敌人情志混乱而且憔悴。

②不虞:未意科,未预料。

③坤下兑上:萃卦为异卦相叠(坤下兑上)。上卦为兑,兑为泽;下并为坤,坤为地。有泽水淹及大地,洪水横流之象。

此计是运用“坤下兑上”之卦象的象理,喻“敌志乱萃”而造成了错失丛杂、危机四伏的处境,我则要抓住敌人这不能自控的混乱之势,机动灵活地运用时东时西,似打似离,不攻而示它以攻,欲攻而又示之以不攻等战术,进一步造成敌人的错觉,出其不意地一举夺胜。

【按语】

西汉,七国反,周亚夫坚壁不战。吴兵奔壁之东南陬,亚夫便备西北;已而吴王精兵果攻西北,遂不得入。此敌志不乱,能自去也。汉末,朱隽围黄巾于宛,张围结垒,起土山以临城内,鸣鼓攻其西南,黄巾悉众赴之,隽自将精兵五千,掩其东北,遂乘虚而人。此敌志乱萃,不虞也。然则声东击西之策,须视敌志乱否为定。乱,则胜;不乱,将自取败亡,险策也。

【解析】

这则按语通过使用此计的两个战例,来提醒使图此计的人必须考虑对手的情况:敌方指挥确可扰乱,用此计必胜,如果对方指挥官头脑冷静,识破计谋,此计就不可能发挥效力了。黄巾军中了李隽佯攻西南方之计,遂丢失宛城(今河南南阳)。而周亚夫处变不惊,识破敌方计谋。吴军佯攻东南角,周亚夫下令加强西北方向的防守。当吴军主力进攻西北角时,周亚夫早有准备,吴军无功而返。

声东击西之计,早已被历代军事家熟知,所以使用时必须充分估计敌方情况。方法虽是一个,但可变化无穷。

【探源】

声东击西,是忽东忽西,即打即离,制造假象,引诱敌人作出错误判断,然后乘机歼敌的策略。为使敌方的指挥发生混乱,必须采用灵活机动的行动,本不打算进攻甲地,却佯装进攻;本来决定进攻乙地,却不显出任何进攻的迹象。似可为而不为,似不可为而为之,敌方就无法推知己方意图,被假象迷惑,作出错误判断。

东汉时期,班超出使西域,目的是团结西域诸国共同对抗匈奴。为了使西域诸国便于共同对抗匈奴,必须先打通南北通道。地处大漠西缘的莎车国,煽动周边小国,归附匈奴,反对汉朝。班超决定首先平定莎车。莎车国王北向龟兹求援,龟兹王亲率五万人马,援救莎车。班超联合于阗等国,兵力只有二万五千人,敌众我寡,难以力克,必须智取。班超遂定下声东击西之计,迷惑敌人。他派人在军中散布对班超的不满言论,制造打不赢龟兹,有撤退的迹象。并且特别让莎车俘虏听得一清二楚。这天黄昏,班超命于阗大军向东撤退.自己率部向西撤退,表面上显得慌乱,故意放俘虏趁机脱逃。俘虏逃回莎车营中,急忙报告汉军慌忙撤退的消息。龟兹王大喜,误认班超惧怕自己而慌忙逃窜,想趁此机会,追杀班超。他立刻下令兵分两路,追击逃敌。他亲自率一万精兵向西追杀班超。班超胸有成竹,趁夜幕笼罩大漠,撤退仅十里地,部队即就地隐蔽。龟兹王求胜心切,率领追兵从班超隐蔽处飞驰而过,班超立即集合部队,与事先约定的东路于阗人马,迅速回师杀向莎车。班超的部队如从天而降,莎车猝不及防,迅速瓦解。莎车王惊魂未定,逃走不及,只得请降。龟兹王气势汹汹,追走一夜,未见班超部队踪影,又听得莎车已被平定,人马伤亡稍重的报告,大势已去,只有收拾残部,悻悻然返回龟兹。

【故事】

台湾被荷兰殖民者统治数十年,民族英雄郑成功立志收复台湾。1661年4月,郑成功率二万五千将士顺利登上澎湖岛。要占领台湾岛,赶走殖民军,必须先攻下赤嵌城(今台南安平)。郑成功亲自寻访熟悉地势的当地老人,了解到攻打赤嵌城只有两条航道可进:一条是攻南航道,这条道港阔水深,船只可以畅通无阻,又较易登陆。荷兰殖民军在此设有重兵,工事坚固,炮台密集,对准海面,另一条是攻北航通,直通鹿耳门。但是这条航道海水很浅,礁石密布,航通狭窄。殖民军还故意凿沉一些船只,阻塞航道。他们认为这里无法登陆,所以只派少量兵力防守。郑成功又进一步了解到,这条航道虽浅,但海水涨潮时,仍可以通大船。于是决定趁涨潮时先攻下鹿耳门,然后绕道从背后攻打赤嵌玻。

郑成功计划已定;首先派出部分战舰,浩浩荡荡,装作从南航道进攻。荷兰殖民军急忙调集大批军队防守航道。为了迷惑敌人,郑成功的部队声威浩大,喊声震天,炮火不断。这一下,郑成功非常成功地把殖民军的注意力全部吸引到了南航道。北航道上一片沉寂,殖民军以为平安无事。南航道激战正酣,在一个月明星稀之夜,郑成功率领主力战舰,人不知,鬼不觉,乘海水涨潮时机迅速登上鹿耳门,守军从梦中惊醒,发现已被包围。郑成功乘胜进兵,从背后攻下赤嵌城。荷兰殖民军狼狈逃窜,台湾又回到祖国怀抱。
