《六韬·虎韬·绝道》
武王问太公说： 率领军队深人敌国境内，与敌军对峙抗衡，这时敌人截断了我军运输粮食的通道，并迂回到我军后方，从前后两方面夹击我军。我军想要进攻又不能胜利，要防守又不能长久。这种情况应该怎么做呢？ 
武王问太公曰： 引兵深入诸侯之地，与敌相守，敌人绝我粮道，又越我前后，吾欲战则不可胜，欲守则不可久，为之奈何？ 
King Wu asked Grand Master Jiang: When I lead my army deep into enemy territory and face off their army, if the enemy cuts off our grain supplies and outflanks us from our rear, attacking us from both the front and back, what should our army do if we cannot win if we attack, but cannot hold out for long if we defend?
