were　left　to　give　the　besieged　a　chance　to　escape　if　they　would。

Now；　outside　the　south　gate　of　Luocheng　the　country　was　rough　and　hilly；　while　the　swift　River　Fu　ran　past　the　north。　For　this　reason　the　city　could　not　be　surrounded。　From　the　city　wall；　Zhang　Ren　watched　the　progress　of　the　attack　and　saw　Liu　Bei　the　whole　day　indefatigably　going　to　and　fro　directing　the　assault。　He　also　saw　that　as　the　sun　dropped　toward　the　west；　the　attacking　force　showed　signs　of　weariness。　Wherefore　he　sent　his　two　generals；　Wu　Lan　and　Lei　Tong；　out　of　the　city　by　the　north　gate　with　orders　to　make　their　way　around　and　attack　Huang　Zhong　and　Wei　Yan。　Zhang　Ren　set　himself　to　go　out　by　the　south　gate　and　steal　around　to　attack　Liu　Bei。　Lest　the　withdrawal　of　troops　from　the　ramparts　should　discover　his　plans；　he　sent　the　populace　up　on　the　walls　to　make　a　show　and　bade　them　shout　loudly　to　reinforce　the　rolling　of　the　drums。

〃An　ambush　in　front；　pursuers　in　rear！　Surely　Heaven　wishes　to　destroy　me！〃　cried　Liu　Bei。

But　all　was　not　lost。　As　they　drew　nearer；
