English translation
Sun Tzu said: In matters of warfare, when chariots are driven by thousands, wagons numbered by the hundreds, armored men amounting to a hundred thousand, and provisions must be supplied for a thousand li, then internal and external expenses, the costs for guests, materials like glue and lacquer, and the provision and maintenance of chariots and armor will come to a daily cost of a thousand pieces of gold; only then can an army of one hundred thousand be raised. In the employment of arms, what matters most is victory; if the campaign is prolonged, weapons grow blunt and edge is lost, assaults on cities sap strength, and long exposure of troops exhausts the state's resources. When weapons are dulled and edge lost, when strength is bent and treasure spent, feudal lords seize the opportunity to rise; even the wise cannot remedy what follows. Hence among soldiers one hears praise of clumsy speed but not of skilful delay. There has never been a case where protracted warfare benefited the state. Therefore one who does not fully understand the harms of using arms cannot fully understand their benefits.
Chinese source
孫子曰：凡用兵之法，馳車千駟，革車千乘，帶甲十萬，千里饋糧，則內外之費，賓客之用，膠漆之材，車甲之奉，日費千金，然後十萬之師舉矣。其用戰也，貴勝，久則鈍兵挫銳，攻城則力屈，久暴師則國用不足。夫鈍兵挫銳，屈力殫貨，則諸侯乘其弊而起，雖有智者，不能善其後矣。故兵聞拙速，未睹巧之久也。夫兵久而國利者，未之有也。故不盡知用兵之害者，則不能盡知用兵之利也。
A competent commander does not levy the same men twice nor requisition grain for three successive years; he takes what is needed from his own state only as necessary and lives off the enemy's supplies, and so the army's rations will suffice.
Chinese source
善用兵者，役不再籍，糧不三載；取用於國，因糧於敵，故軍食可足也。
When a state's army is provisioned from afar, long transport impoverishes the people; when the army is close, prices rise and people are forced to sell at high cost, exhausting their wealth and driving them into corvée. Strength is strained and the treasury exhausted; the heartland and households lie empty. Of the people's resources, seven tenths are consumed; of the public's resources—broken carts and idle horses, armor, arrows and crossbows, halberds, shields, siege engines, draft oxen and large wagons—six tenths are consumed.
Chinese source
國之貧於師者遠輸，遠輸則百姓貧；近師者貴賣，貴賣則百姓財竭，財竭則急於丘役。力屈財殫，中原內虛於家。百姓之費，十去其七；公家之費，破車罷馬，甲胄矢弩，戟楯蔽櫓，丘牛大車，十去其六。
Therefore a wise general strives to feed his troops from the enemy: one measure taken from the enemy may be worth twenty of ours; one bundle of their straw may be worth twenty of ours.
Chinese source
故智將務食於敵，食敵一鍾，當吾二十鍾；萁稈一石，當吾二十石。
Killing the enemy comes from anger; taking the enemy's goods is profit. Thus in chariot battles, when you capture ten or more chariots, reward those who captured them first and replace the captured banners. Mix captured chariots into your own ranks, use competent captured soldiers and feed them well—this is called defeating the enemy and increasing your strength.
Chinese source
故殺敵者，怒也；取敵之利者，貨也。故車戰，得車十乘以上，賞其先得者，而更其旌旗。車雜而乘之，卒善而養之，是謂勝敵而益強。
Hence in war what is prized is victory, not duration. Therefore the general who understands warfare holds the people's lives in his hands and is the arbiter of the state's safety and peril.
Chinese source
故兵貴勝，不貴久。故知兵之將，民之司命，國家安危之主也。
