《资治通鉴·魏纪·魏纪六》
如果我们不出动全部大军，只是象以前一样出动少量部队，则不足以完成大事，容易屡屡败退，民众疲沓，军威消失，时间过去，力量耗竭。这不是上策。 
若不悉军动众，循前轻举，则不足大用，易于屡退，民疲威消，时往力竭，非上策也。 
If we do not dispatch all troops, but perform a limited attack as we did before, then we will not accomplish great things. The army will likely retreat repeatedly. The people will be exhausted and the army will no longer be imposing. With the passage of time, our strength will be depleted. This is not a good strategy.
