proceed　secretly　into　those　mountains　in　front。　When　you　see　that　Zhang　Yi　and　Wang　Ping　are　in　great　straits　with　the　enemy；　then　open　the　bag　and　you　will　find　a　plan　of　escape。〃

After　this　he　gave　secret　instructions　to　four　other　generals………Hu　Ban；　Wu　Yi；　Ma　Zheng；　and　Zhang　Ni………to　observe　the　enemy　and；　if　the　enemy　seemed　confident　of　victory；　to　retire；　fighting　at　intervals；　till　they　saw　Guan　Xing　e　up；　when　they　could　turn　and　fight　their　best。

Then　calling　Guan　Xing；　he　said　to　them；　〃Hide　in　the　valleys　with　five　thousand　troops　till　you　see　a　red　flag　flutter　out；　and　then　fall　on　the　enemy。〃

Zhang　He　and　Dai　Ling　hurried　along　like　a　rain　squall　till　they　were　suddenly　confronted　by　Ma　Zheng；　Zhang　Ni；　Wu　Yi；　and　Hu　Ban。　Zhang　He　dashed　toward　his　enemy；　and　then　they　retired；　stopping　at　intervals　to　fight。　The　Wei　army　pursued　for　about　seven　miles。

It　was　the　sixth　moon　and　very　hot；　so　that　soldiers　and　horses　sweated　profusely。　When　they　had　gone　ten　miles　farther；　the　soldiers　and　horses　were　panting　and　nearly　spent。　Then　Zhuge　Liang；　who　had　watched　the　fighting　from　a　hill；　gave　the　signal　for　Guan　Xing　to　emerge　and　join　battle。　Ma　Zheng；　Zhang　Ni；　Hu　Ban；　and　Wu　Yi　all　led　on　their　troops。　Zhang　He　and　Dai　Ling　fought　well；　but　they　could　not　extricate　themselves　and　retire。

Presently；　with　a　roll　of　drums；　Wang　Ping　and　Zhang　Yi　came　out　and　made　for　the　rear　to　cut　the　retreat。

〃Why　do　you　not　fight　to　death？〃　shouted　Zhang　He　to　his　generals　when　he　saw　the　new　dangers。

The　soldiers　of　Wei　dashed　this　way　and　that；　but　were　stayed　at　every　attempt。　Then　there　was　heard　another　roll　of　drums；　and　Sima　Yi　came　up　in　the　rear。　He　at　once　signaled　to　his　generals　to　surround　Wang　Ping　and　Zhan
