Ma Han 馬漢

In Chapter 65 of the Romance, Ma Chao at Jiameng Pass, heeding Li Hui's words, summons Yang Bai and cuts him down with a single stroke of his sword, then, taking his head, goes up to the pass together with Li Hui and surrenders to Xuande. Xuande welcomes him in person and treats him with the courtesy due to an honored guest, has Huo Jun and Meng Da guard the pass, and withdraws his troops to go and take Chengdu. Zhao Yun and Huang Zhong welcome him into Mianzhu, and a report comes in that the Shu generals Liu Jun and Ma Han have arrived leading troops. Romance, Ch. 65 §35–36

Zhao Yun says that he himself will go and capture these two men, mounts his horse and leads his troops out. While Xuande is entertaining Ma Chao with wine on the city wall, before they have even settled into their seats, Zhao Yun has already cut off the two men's heads and presents them before the feast. Ma Chao too is astonished and treats him with redoubled respect and esteem, and says that there is no need for his lord's troops to fight: he will call Liu Zhang out himself and make him surrender, and if Liu Zhang will not surrender, he and his younger brother Ma Dai will take Chengdu and offer it up. Romance, Ch. 65 §36–37

When the defeated soldiers return to Yi Province and report, Liu Zhang is greatly alarmed and shuts the gates and does not come out. When Ma Chao and Ma Dai come below the walls and shout to him to offer up his land and surrender, Liu Zhang, in shock, faints on the city wall, and on coming to, says that he would rather open the city gates and surrender to save the people of the whole city. In the Romance, Ma Han's name appears in only one place: the report that he has come leading troops together with Liu Jun. Romance, Ch. 65 §36 · 38–39
