Nguyễn Nhạc
Nguyễn Nhạc did not want to take northern Vietnam; he sent an envoy to Phú Xuân to prevent Huệ from marching north, but Huệ had left. Then he got the message that Huệ had captured Thăng Long, and realized that Huệ was hard to be controlled. Nhạc led 2500 men and marched north to meet with Huệ and the Lê emperor. In Thăng Long, Nhạc promised that he would not take any territory of Lê emperor. Then Nhạc retreated from Thăng Long together with Huệ. Vũ Văn Nhậm disliked Nguyễn Hữu Chỉnh, and persuaded Huệ to leave Chỉnh in northern Vietnam. Huệ led his army back to Phú Xuân secretly. Chỉnh abandoned all his property, and came to Nghệ An to join Tây Sơn army. Nguyễn Nhạc did not have the heart to abandon him again; Chỉnh was left in Nghệ An together with a Tây Sơn general, Nguyễn Văn Duệ.
