Who's Shamok? The more detailed, the better.

Shamok (? -222), the leader of Wuxi men in the Three Kingdoms period at the end of the Eastern Han Dynasty. At the beginning of the first year of Zhangwu (22 1), Emperor Wu of the Han Dynasty, in order to avenge Guan Yu's murder by Wu Dong, Liu Bei personally led the troops to attack Sun Quan and rewarded Sha Jin Jue.

In the second year of Zhangwu (222), Lu Xun, commander-in-chief of Wuda University, attacked Liu Bei with fire and led all the troops to strike together. More than forty camps of the Han army were breached, and Sha fled in disorder and was killed by the rebels.

In July of the first year of Zhangwu (22 1), Liu Bei led the Shu-Han army to crusade, and Shu-Han generals Wu Ban and Feng split their troops from Wu Shan, and the Han army advanced Zigui. The Wu people sent messengers to Wu Ban and Feng to ask the Han army to send troops.

In February of the second year of Zhangwu (222), Liu Bei personally marched from Zigui to the xiāo Pavilion, which opened a road from Yishan to Wuling County, sent assistant minister Ma Liang to settle and comfort the Wu people, gave him gold and brocade, and awarded him official positions and titles. Wu people have responded to the call. In June, Wu Dong's general commander Lu Xun attacked the Han army and then led the troops to attack at the same time. The generals of the Han army, Feng and Sha were beheaded and put to death, and more than 40 battalions of the Han army were breached.
