At the end of July, due to a lack of food supplies, Lu Yuan, who had already led his troops to arrival in Liang County and was besieging the city of Daliang, had no choice but to temporarily cease military operations and withdraw his forces back to East Sea County.
To shorten the supply lines and reduce logistical pressure.

Upon returning to East Sea, Lu Yuan felt somewhat depressed.
This campaign against Liang County had ended abruptly. Hardly had he laid siege to Daliang when he was forced to withdraw his troops.
Millions of soldiers had marched back and forth to no avail, leaving no one contented with the outcome.
Yet discontent as he was, he had to accept the situation.
With so many issues locally and major flooding occurring behind the lines, along with a succession of natural disasters and man-made calamities, the joy over the victories of the Northern Expedition had been considerably diminished.
