sent to Luoyang for public display. A separate fleet, led by future Grand Administrators Liu Xin () and Xianyu Si (), had been sent to attack the Korean commanderies of Lelang and Daifang by sea, and in time, all of Gongsun Yuan's state of Liaodong was subjugated. Aftermath Entering the city, Sima Yi assembled all of those who had served in Gongsun Yuan's military and government under two banners. Everyone who had held office in Gongsun Yuan's rebel regime, 1,000 to 2,000 in number, were executed in a systematic purge. In addition, 7,000 people of age 14 and above who had served in Liaodong's army were put to death, their corpses heaped up to form a great mound meant to terrorise those who survived. After the massacre, he pardoned the survivors, posthumously rehabilitated Lun Zhi () and Jia Fan () — two of Gongsun Yuan's subordinates who opposed going to war with Wei — and freed the overthrown Gongsun Gong from jail. Finally, he dismissed the soldiers over 59 years of age from the Wei army on grounds of compassion, numbering over a thousand men, and marched back with the army.

When someone pointed out that they had a surplus of ru () and suggested giving them out to the soldiers, Sima Yi refused and said that the rus were the property of the Wei government and should not be distributed without permission. Although he had gained 40,000 households and some 300,000 people for the state of Wei from this expedition, Sima Yi did not encourage these frontier settlers to continue their livelihoods in the Chinese northeast and instead ordered that those families who wished to return to central China be allowed to do so. In April or May 239, a Wu fleet commanded by Sun Yi () and Yang Dao defeated the Wei defenders in southern Liaodong, prompting the Wei imperial court to evacuate the coastal population to Shandong, further accelerating the trend of depopulation in Liaodong. This happened around the same time as the Xianbei chieftain Mohuba was awarded merit for his participation in the campaign against Gongsun Yuan, and his people were allowed to settle in northern Liaodong. By the beginning of the Western Jin dynasty (265-316), the number of Chinese households fell to just 5,400. After the
