Ngô Văn Sở

Ngô Văn Sở (吳文楚, died 1795) was a general of the Tây Sơn dynasty.

Nhậm occupied Thăng Long (modern Hanoi), executed Nguyễn Hữu Chỉnh, and installed Lê Duy Cận as a puppet "Prince Regent" (監國 giám quốc).

The emperor then left Tonkin, leaving Sở, Lân, Nguyễn Văn Tuyết, Nguyễn Văn Dụng, Trần Thuận Ngôn, and Ngô Thì Nhậm in Thăng Long to watch over Cận.

[2] Realizing the Tây Sơn army could not stop the Chinese army from marching to Thăng Long, Sở accepted the suggestion of Nhậm, abandoned Thăng Long, and retreated to Tam Điệp, and sent Nguyễn Văn Tuyết to Phú Xuân (mordern Huế) to ask support.

Dũng was ordered to return to Phú Xuân, but on the way there, Trần Văn Kỷ persuaded him to stage a coup against Tuyên, who was subsequently arrested and thrown into prison.
