[1][2] In December 1386, the Hongwu Emperor ordered General Feng Sheng to lead an army of 200,000 soldiers against the Mongols.

[3] In early 1387, Feng Sheng was commissioned as the Grand General, assigned Fu Youde and Lan Yu to assist him, and raised a large army.

[3] On 20[2] March 1387, General Feng Sheng led the Ming army northward through the Great Wall.

[2][3] Fortresses were constructed at Daning (大寧), Fuyu (富峪), Huizhou (會州), and Kuanhe (寛河) near the Great Wall of China and completed at the end of the summer of 1387.

[3] Meanwhile, General Lan Yu and his army inflicted much destruction to portions of the Mongol horde in the northern vicinity of the Great Wall.

[3] In the period after his surrender to the Ming, Naghachu was given a marquisate with a stipend of 2,000 piculs of grain, an estate of public fields in Jiangxi, and a mansion in Nanjing.

[3] Bolstered by this successful campaign, the Hongwu Emperor ordered General Lan Yu to lead 150,000 men on a military campaign against Toghus Temur, the Mongol Khan, culminating in the Ming victory over the Mongol horde at the Battle of Buir Lake in 1388.
