For 迫, the _T‘u Shu_ reads 追 “pursue.” Ch‘ên Hao quotes the saying: 鳥窮則搏獸窮則噬 “Birds and beasts when brought to bay will use their claws and teeth.” Chang Yü says: 敵若焚舟破釜決一戰則不可逼 迫來 “If your adversary has burned his boats and destroyed his cooking-pots, and is ready to stake all on the issue of a battle, he must not be pushed to extremities.” The phrase 窮宼 doubtless originated with Sun Tzŭ. The _P‘ei Wên Yün Fu_ gives four examples of its use, the earliest being from the _Ch‘ien Han Shu_, and I have found another in chap. 34 of the same work. Ho Shih illustrates the meaning by a story taken from the life of 符彥卿 Fu Yen-ch‘ing in ch. 251 of the 宋史. That general, together with his colleague 杜重威 Tu Chung-wei, was surrounded by a vastly superior army of Khitans in the year 945 A.D. The country was bare and desert-like, and the little Chinese force was soon in dire straits for want of water. The wells they bored ran dry, and the men were reduced to squeezing lumps of mud and sucking out the moisture. Their ranks thinned rapidly, until at last Fu Yen-ch‘ing exclaimed: “We are desperate men. Far better to die for our country than to go with fettered hands into captivity!” A strong gale happened to be blowing from the north-east and darkening the air with dense clouds of sandy dust. Tu Chung-wei was for waiting until this had abated before deciding on a final attack; but luckily another officer, 李守貞 Li Shou-chêng by name, was quicker to see an opportunity, and said: “They are many and we are few, but in the midst of this sandstorm our numbers will not be discernible; victory will go to the strenuous fighter, and the wind will be our best ally.” Accordingly, Fu Yen-ch‘ing made a sudden and wholly unexpected onslaught with his cavalry, routed the barbarians and succeeded in breaking through to safety. [Certain details in the above account have been added from the 歴代紀事年表, ch. 78.] 37. 此用兵之法也 Such is the art of warfare. Chêng Yu-hsien in his 遺說 inserts 妙 after 法. I take it that these words conclude the extract from the 軍政 which began at § 23. VIII. 九變篇 VARIATION OF TACTICS.
