When Liu Bei's forces showed up, Zhang Ren led his men to engage the enemy at Yan Bridge (鴈橋) but was defeated and captured alive.

[4] Zhang Ren's grave is located in Weigan Village (桅杆村), Beiwai District (北外鄉), Guanghan, Sichuan.

During the reign of the Jiaqing Emperor in the Qing dynasty, the local government erected a tombstone for the grave with the words "Tomb of the Han General Zhang Ren" (漢將軍張公任之墓) inscribed on it.

The brick serves as evidence that the tomb was constructed in as early as 296 during the Yuankang era (291–300) of the reign of Emperor Hui in the Western Jin dynasty.

After Zhang Ren is captured alive, Liu Bei asks him to surrender but he firmly refuses and is executed.
