the 8,000 troops out of the valley, where they had been waiting in ambush earlier. When Lu Xun heard about it, he told his subordinates, "The reason why I didn't follow your suggestions to attack the enemy is because I suspected there was something fishy about it." He then wrote a report to Sun Quan: Burning of the Shu camps The Wu generals said, "We should have attacked Liu Bei in the initial stages. Now, he has advanced further in by 500-600 li and we have been locked in a stalemate for seven to eight months. He has reinforced all his crucial positions, so even if we attack them it will yield nothing." Lu Xun replied, "Liu Bei is cunning and experienced. In the initial stage, his army was very focused and its morale was very high, so we couldn't defeat them then. Now, however, since it has been quite some time, they are already weary, low on morale, and out of ideas. Now is the time for us to launch a multi-pronged assault on them." Lu Xun then targeted one enemy camp and attacked it but failed to capture it. The Wu officers complained, "We're sacrificing our soldiers' lives for nothing." Lu Xun replied, "I have devised a strategy for defeating the enemy." He then ordered his men to carry a pile of straw each and launch a fire attack on the enemy. Upon the commencement of the fire attack, Lu Xun led all the Wu units on an all-out assault on the Shu forces. The Shu generals Zhang Nan and Feng Xi, and the tribal king Shamoke (Liu Bei's ally) were killed in battle, while the Wu forces destroyed over 40 Shu camps. The Shu officers Du Lu (), Liu Ning () and others surrendered when they saw they had no chance of escaping. Liu Bei and his remaining troops retreated to the Ma'an Hills (), where they continued to be fiercely assaulted by Wu forces from all directions. At the same time, landslides occurred at the Ma'an Hills and caused the Shu forces to suffer thousands of casualties. Liu Bei fled at night and ordered his men to pile up their armour and set them on fire to create barriers for the pursuing enemy. By the time Liu Bei reached the safety of Baidicheng, all his boats, military equipment and supplies had been captured by Wu forces.
