sentences:  Du Yuming, the nationalist frontline commander was well aware that his exhausted force must rest and regroup for sometime before launching anymore attacks on the enemy.Furthermore, Du and his fellow officers were also keenly aware that the majority of the enemy force in the rural regions was unscathed and was waiting to ambush them out in the open if the exhausted nationalists had ventured into the terrain hostile to the mechanized force.Du and his officers were determined not to give the enemy the opportunity they had been waiting for, and in a rare example among Chiang's most trusted subordinates, Du Yuming refused to carry out Chiang's order and successfully convinced Chiang to stop the planned offensive to allow the nationalists to consolidate their gains in Northeast China, and thus foiled the enemy's hope of possible ambush.
