Yujiulü Wuti

In 432, Northern Wei captured 20 Rouran warriors at the border, but Emperor Taiwu pardoned them.

At the encouragement of the prime minister Cui Hao, Emperor Taiwu again prepared military action.

With Yuan He, the son of Southern Liang's last prince Tufa Rutan, as guide, he launched a speedy attack and arrived at Guzang quickly.

Juqu Mujian, in shock, refused to surrender, defending the city against a siege, while seeking immediate military assistance from Wuti.

Yujiulü Wuti did launch a surprise attack on Pingcheng to try to force Emperor Taiwu to give up the campaign, but after initial successes, he failed to capture Pingcheng, and his brother Yujiulü Qiliegui (郁久閭乞列歸) was captured by Northern Wei forces.
