ambushes, and therefore induce the enemy to retreat. It is listed as the 32nd of the <i><a href="/wiki/Thirty-Six_Stratagems" title="Thirty-Six Stratagems">Thirty-Six Stratagems</a></i>. Some examples are listed in the following sections. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Cao_Cao">Cao Cao</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Empty_Fort_Strategy&action=edit&section=1" title="Edit section: Cao Cao"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>According to the <i><a href="/wiki/Records_of_the_Three_Kingdoms" title="Records of the Three Kingdoms">Sanguozhi</a></i>, in 195, the Empty Fort Strategy was used by the warlord <a href="/wiki/Cao_Cao" title="Cao Cao">Cao Cao</a> against his rival <a href="/wiki/L%C3%BC_Bu" title="Lü Bu">Lü Bu</a> in one incident at Chengshi County (乘氏縣; southwest of present-day <a href="/wiki/Juye_County" title="Juye County">Juye County</a>, <a href="/wiki/Shandong" title="Shandong">Shandong</a>). In the summer of that year, Lü Bu went to Dongmin County (東緡縣; northeast of present-day <a href="/wiki/Jinxiang_County" title="Jinxiang County">Jinxiang County</a>, Shandong) and gathered about 10,000 troops to attack Cao Cao. At the time, Cao Cao had very few soldiers with him, but he set up an ambush and managed to defeat Lü Bu.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>The <i>Wei Shu</i> (魏書) gave a more detailed account of the ambush. Cao Cao had sent most of his troops out to collect grain so he had less than 1,000 men available in his base, which could not be well defended with so few men. When Lü Bu showed up, Cao Cao ordered all his available soldiers to defend the base and even ordered women to stand guard on the walls. To the west of Cao Cao's base was a dyke, and to its south was a deep forest. Lü Bu suspected that there was an ambush, so he told his men, "Cao Cao is very cunning. We must not fall into his ambush." He then led his troops to 10 <i><a href="/wiki/Li_(unit)" title="Li (unit)">li</a></i> (Chinese miles) south of Cao Cao's base and set up his camp there. The next day, Lü Bu came to attack Cao Cao, and by then, Cao Cao had really set up an ambush near the dyke with the soldiers that had returned from gathering the grain. Lü Bu's forces fell into the ambush and were defeated.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>The "ambush" mentioned in the <i>Sanguozhi</i> refers to the ambush that Lü Bu's forces fell into a trap on the second day, as described in the <i>Wei Shu</i>. The incident is also mentioned in <a href="/wiki/Sima_Guang" title="Sima Guang">Sima Guang</a>'s <i><a href="/wiki/Zizhi_Tongjian" title="Zizhi Tongjian">Zizhi Tongjian</a></i>. However, the <i>Zizhi Tongjian</i> account, which combined the <i>Sanguozhi</i> and <i>Wei Shu</i> accounts, did not mention the events on the first day – which were about Cao Cao sending all his available soldiers to defend the base and ordering women to stand guard on the walls.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Debate">Debate</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Empty_Fort_Strategy&action=edit&section=2" title="Edit section: Debate"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><a href="/wiki/Yi_Zhongtian" title="Yi Zhongtian">Yi Zhongtian</a>, a history professor from <a href="/wiki/Xiamen_University" title="Xiamen University">Xiamen University</a>, commented on this incident in his book <i>Pin San Guo</i> (品三国) in response to criticism from <a href="/wiki/Fudan_University" title="Fudan University">Fudan University</a> historian <a href="/wiki/Zhou_Zhenhe" title="Zhou Zhenhe">Zhou Zhenhe</a> and an online commentator known as "Hongchayangweili" (红茶杨威利). Earlier on, Yi referred to this incident when he said in a lecture on the television programme <i><a href="/wiki/Lecture_Room" title="Lecture Room">Lecture Room</a></i> that "Cao Cao's rights to the invention of the Empty Fort Strategy had been stolen from him". Zhou claimed that the Empty Fort Strategy had never been used in history before so there were no "rights" to its invention; the online commentator argued that the incident does not count as a use of the Empty Fort Strategy. </p><p>Yi defended his claim and said that the incident in 195 is valid because of the circumstances under which it was used, which were very similar to the incidents involving <a href="/wiki/Zhao_Yun" title="Zhao Yun">Zhao Yun</a> and <a href="/wiki/Wen_Ping" title="Wen Ping">Wen Ping</a> (see the sections below). Cao Cao was trying to confuse Lü Bu by making use of the geographical features (the "deep forest") and by ordering women to stand guard on the walls, so as to make Lü Bu suspect that he had set up an ambush in the "deep forest" and lure Lü Bu to attack his "weakly defended" base by deploying women as soldiers to show how "desperate" he was to set up a defence. The ploy worked because it made Lü Bu hesitate when he wanted to attack. Cao Cao had bought sufficient time to set up a real ambush, and he defeated Lü Bu when he came to attack again on the following day.<sup id="cite_ref-Yi_Zhongtian_Pin_San_Guo_4-0" class="reference"><a href="#cite_note-Yi_Zhongtian_Pin_San_Guo-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Zhao_Yun">Zhao Yun</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Empty_Fort_Strategy&action=edit&section=3" title="Edit section: Zhao Yun"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The <i>Zhao Yun Biezhuan</i> (趙雲別傳; <i>Unofficial Biography of Zhao Yun</i>) mentioned an incident about <a href="/wiki/Zhao_Yun" title="Zhao Yun">Zhao Yun</a>, a general under the warlord <a href="/wiki/Liu_Bei" title="Liu Bei">Liu Bei</a>, using the Empty Fort Strategy during the <a href="/wiki/Battle_of_Han_River" title="Battle of Han River">Battle of Han River</a> in 219, fought between Liu Bei and his rival <a href="/wiki/Cao_Cao" title="Cao Cao">Cao Cao</a> as part of the <a href="/wiki/Hanzhong_Campaign" title="Hanzhong Campaign">Hanzhong Campaign</a>. </p><p>This incident took place after Cao Cao's general <a href="/wiki/Xiahou_Yuan" title="Xiahou Yuan">Xiahou Yuan</a> was defeated and killed in action at the earlier <a href="/wiki/Battle_of_Mount_Dingjun" title="Battle of Mount Dingjun">Battle of Mount Dingjun</a>.

When Huang Zhong did not return after a long time, Zhao Yun led tens of horsemen in search of Huang. Zhao Yun's search party encountered Cao Cao's forces and engaged them in battle but were outnumbered and was forced to retreat back to camp with Cao Cao's men in pursuit. Zhao Yun's subordinate <a href="/wiki/Zhang_Yi_(Bogong)" title="Zhang Yi (Bogong)">Zhang Yi</a> wanted to close the gates of the camp to prevent the enemy from entering. However, Zhao Yun gave orders for the gates to be opened, all flags and banners to be hidden, and the war drums silenced. Cao Cao's forces thought that there was an ambush inside Zhao Yun's camp so they withdrew. Just then, Zhao Yun launched a counterattack and his men beat the war drums loudly and fired arrows at the enemy. Cao Cao's soldiers were shocked and thrown into disarray.

When Wen Ping heard that Sun Quan had arrived, he was unsure of what to do, but eventually formulated a plan to deceive him. He ordered everyone in the fortress to stay under cover while he hid behind the walls, creating an illusion of an empty fortress. As Wen Ping expected, Sun Quan became suspicious and he said to his subordinates, "The northerners regard this man (Wen Ping) as a loyal subject, which is why they entrusted him with defending this commandery. Now, as I approach, he does not make any move. It must be either that he has something up his sleeve or that his reinforcements have arrived."

Zhuge Liang later explained that his strategy was a risky one. It worked because Zhuge Liang had a reputation for being a careful military tactician who hardly took risks, so Sima Yi came to the conclusion that there was certainly an ambush upon seeing Zhuge's relaxed composure.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="As_a_topic_of_academic_study">As a topic of academic study</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Empty_Fort_Strategy&action=edit&section=6" title="Edit section: As a topic of academic study"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Christopher Cotton, an economist from the <a href="/wiki/Queen%27s_University_at_Kingston" title="Queen's University at Kingston">Queen's University</a>, and Chang Liu, a graduate student, used <a href="/wiki/Game_theory" title="Game theory">game theory</a> to model the bluffing strategies used in the Chinese military legends of <a href="/wiki/Li_Guang" title="Li Guang">Li Guang</a> and his 100 horsemen (144 BC), and Zhuge Liang and the Empty City (228 AD).

He left behind only 10,000 men to defend Yangping. Sima Yi led 200,000 troops to attack Zhuge Liang and he took a shortcut, bypassing Wei Yan's army and arriving at a place 60 <i><a href="/wiki/Li_(unit)" title="Li (unit)">li</a></i> away from Zhuge Liang's location. Upon inspection, Sima Yi realised that Zhuge Liang's city was weakly defended. Zhuge Liang knew that Sima Yi was near, so he thought of recalling Wei Yan's army back to counter Sima Yi, but it was too late already and his men were worried and terrified. Zhuge Liang remained calm and instructed his men to hide all flags and banners and silence the war drums. He then ordered all the gates to be opened and told his men to sweep and dust the ground. Sima Yi knew that impression that Zhuge Liang was a cautious and prudent man, and he was baffled by the sight before him and suspected that there was an ambush. He then withdrew his troops. The following day, Zhuge Liang clapped his hands, laughed, and told an aide that Sima Yi thought that there was an ambush and had withdrawn. Later, his scouts returned and reported that Sima Yi had indeed retreated. Sima Yi was very upset when he later found out about the ruse.<sup id="cite_ref-12" class="reference"><a href="#cite_note-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup></p></blockquote><p> After adding the anecdote to Zhuge Liang's biography, Pei Songzhi wrote a short commentary as follows: <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1244412712"></p><blockquote class="templatequote"><p>When Zhuge Liang garrisoned at Yangping, Sima Yi was serving as the Area Commander of <a href="/wiki/Jing_Province" class="mw-redirect" title="Jing Province">Jing Province</a> and he was stationed at Wancheng (宛城; present-day <a href="/wiki/Wancheng_District" class="mw-redirect" title="Wancheng District">Wancheng District</a>, <a href="/wiki/Nanyang,_Henan" title="Nanyang, Henan">Nanyang</a>, <a href="/wiki/Henan" title="Henan">Henan</a>). He only came into confrontation with Zhuge Liang in <a href="/wiki/Guanzhong" title="Guanzhong">Guanzhong</a> after <a href="/wiki/Cao_Zhen" title="Cao Zhen">Cao Zhen</a>'s death (in 231). It was unlikely that the Wei government ordered Sima Yi to lead an army from Wancheng to attack Shu via Xicheng (西城; present-day <a href="/wiki/Ankang" title="Ankang">Ankang</a>, Shaanxi) because there were heavy rains at the time (which obstructed passage). There were no battles fought at Yangping before and after that period of time. Going by Guo Chong's anecdote, if Sima Yi did lead 200,000 troops to attack Zhuge Liang, knew that Zhuge Liang's position was weakly defended, and suspected that there was an ambush, he could have ordered his troops to surround Zhuge Liang's position instead of retreating. Wei Yan's biography mentioned: "Each time Wei Yan followed Zhuge Liang to battle, he would request to command a separate detachment of about 10,000 men and take a different route and rendezvous with Zhuge Liang's main force at <a href="/wiki/Tongguan_County" title="Tongguan County">Tong Pass</a>. Zhuge Liang rejected the plan, and Wei Yan felt that Zhuge Liang was a coward and complained that his talent was not put to good use." As mentioned in Wei Yan's biography, Zhuge Liang never agreed to allow Wei Yan to command a separate detachment of thousands of troops. If Guo Chong's anecdote was true, how was it possible that Zhuge Liang would allow Wei Yan to lead a larger army ahead while he followed behind with a smaller army? Guo Chong's anecdote was endorsed by the Prince of Fufeng (<a href="/wiki/Sima_Jun_(prince)" title="Sima Jun (prince)">Sima Jun</a>, a son of Sima Yi). However, the story puts Sima Yi in a negative light, and it does not make sense for a son to approve a story which demeans his father. We can tell that this anecdote is fake after reading the sentence "the Prince of Fufeng endorsed Guo Chong's anecdote".<sup id="cite_ref-13" class="reference"><a href="#cite_note-13"><span class="cite-bracket">[</span>13<span class="cite-bracket">]</span></a></sup></p></blockquote> <p>Evidence from historical sources indicate that Sima Yi was indeed not in Jieting at the time.
