却说姜维恐救兵到,先将军器车仗一应军需,步兵先退,然后将马军断后。细作报知邓艾。艾笑曰:「姜维知大将军到,故先退去。不必追之,追则中彼之计也。」乃令人哨探,回报果然骆谷狭窄之处,堆积柴草,准备要烧追兵。众皆称艾曰:「将军真神算也!
Fearing lest reinforcements would strengthen his enemy beyond his own power of resistance, Chiang decided to retreat while he could. He sent all his stores and baggage away first with the footmen, and kept the cavalry to cover the retirement. The spies reported his movements to Têng Ai, who said, “He has gone because he knew that the main army would soon be upon him. Let him go, and do not follow. If we pursue he will play us some evil trick.” Scouts were sent to keep in touch with the retreating army, and when they returned they reported that preparations had been made in the Lo Valley to check any pursuit with fire. The officers praised the prescience of their leader. When Têng reported these matters he was commended, and the Prime Minister requested the king to confer a reward.
