Page "Guan Yu" Paragraph 16

After almost a year of fighting, Cao Cao could no longer afford continuous loss of materiel and labor in the siege, and ordered Cao Ren to withdraw from Jiangling fortress.

Liu Bei convinced Sun Quan to lend him Nan Commandery, and stationed Guan Yu in its capital city, Jiangling.

In 213, Liu Bei left for Yi Province ( covering the Sichuan Basin ) and wrestled control of the land from Liu Zhang after two years.

Since then, Guan Yu had been the leading figure of Jing Province.

Most of the Liu Bei's forces went to Yi Province when Liu was experiencing difficulty in his invasion, while Guan Yu and part of Liu's forces remained in Jing Province.
