The good general is the lord of the people's lives, the guardian of the country's welfare. III THE ATTACK BY STRATAGEM Sun the Master said:-- Now by the laws of war, better than defeating a country by fire and the sword, is to take it without strife. Better to capture the enemy's army intact than to overcome it after fierce resistance. Better to capture the "Lu,"[3] the "Tsu" or the "Wu" whole, than to destroy them in battle. To fight and conquer one hundred times is not the perfection of attainment, for the supreme art is to subdue the enemy without fighting. Wherefore the most skilful warrior outwits the enemy by superior stratagem; the next in merit prevents the enemy from uniting his forces; next to him is he who engages the enemy's army; while to besiege his citadel is the worst expedient. A siege should not be undertaken if it can possibly be avoided. For, before a siege can be commenced, three months are required for the construction of stages, battering-rams and siege engines; then a further three months are required in front of the citadel, in order to make the "Chuyin."[4] Wherefore the general is angered, his patience exhausted, his men surge like ants against the ramparts _before the time is ripe_, and one-third of them are killed to no purpose. Such are the misfortunes that sieges entail. Therefore the master of war causes the enemy's forces to yield, but without fighting; he captures his fortress, but without besieging it; and without lengthy fighting takes the enemy's kingdom. Without tarnishing his weapons he gains the complete advantage. This is the assault by stratagem. By the rules of war, if ten times as strong as the enemy, surround him; with five times his strength, attack; with double his numbers, divide. If equal in strength, exert to the utmost, and fight; if inferior in numbers, manoeuvre _and await the opportunity_; if altogether inferior, offer no chance of battle. A determined stand by inferior numbers does but lead to their capture. The warrior is the country's support. If his aid be entire, the country is of necessity strong; if it be at all deficient, then is the country weak. Now a prince may embarrass his army in three ways, namely:-- Ignorant that the army in the field should not advance, to order it to go forward; or, ignorant that the army should not retreat, order it to retire. This is to tie the army as with a string. Ignorant of military affairs, to rule the armies in the same way as the state. This is to perplex the soldiers. Ignorant of the situation of the army, to settle its dispositions. This is to fill the soldiers with distrust. If the army be perplexed and distrustful, then dangers from neighbouring princes arise. The army is confounded, and offered up to the enemy. There are five occasions when victory can be foretold:--
