Li Sheng: The Rise from Right Army General to a Famous General of the Restoration

Brief Introduction

Li Sheng (727–793), courtesy name Liangqi, was from Chengji, Longxi. He was an outstanding military general of the mid-Tang Dynasty, hailed as one of the "Famous Generals of the Restoration." He served through four reigns: Xuanzong, Suzong, Daizong, and Dezong, achieving remarkable military merits in suppressing the An Lushan Rebellion and subsequent warlordism. This article focuses on a key event in his early career: his surprise raid against the Tubo as a "Right Army General," exploring the early demonstration of his military talent.

Core Knowledge Points

1. Identity and Position: In his early career, Li Sheng served under the famous general Li Guangbi, holding the position of "Right Army General." Although this was not the highest command, it granted him the ability to independently command small units of elite troops.
2. Surprise Raid on Tubo: During border conflicts between the Tang Dynasty and the Tubo, Li Sheng keenly seized the opportunity. He led 500 elite cavalrymen, taking advantage of night or enemy unpreparedness, to launch a surprise attack on the Tubo camp. This battle was not only a great victory with significant material gains but also severely damaged Tubo morale.
3. Military Style: This action reflected Li Sheng's military style of being "brave, skilled in combat, and daring to take risks." He excelled in using intelligence and mobility to win battles with fewer troops, laying the foundation for his future role as a commander of a regional army.

Connection with the Content of "Zizhi Tongjian"

As a chronological general history, the Zizhi Tongjian may not record the details of Li Sheng's early official positions as exhaustively as the Old Book of Tang, but its overall narrative logic regarding Li Sheng's life is highly consistent with this account.

1. Continuity of Historical Context: Sima Guang in the Zizhi Tongjian focuses on Li Sheng's heroic deeds in the "Jingyuan Mutiny," where he rescued the emperor and recaptured Chang'an. The early surprise raid on Tubo was the starting point of his military career, explaining how Li Sheng grew from a grassroots general into a pillar of the state capable of handling affairs independently.
2. Verification of Character: The Zizhi Tongjian emphasizes "both talent and virtue." Li Sheng's early merit through surprise raid verified his bravery and strategy; his later efforts to rescue the emperor demonstrated his loyalty and righteousness. Combined, these form the complete image of a loyal minister and capable general under Sima Guang's pen.
3. Reflection of Era Background: This event occurred during the Kaiyuan and Tianbao eras of Emperor Xuanzong, a time when Tubo power was strong and the Tang court faced immense border defense pressure. By recording such battles, the Zizhi Tongjian reflects the evolution of Tang Dynasty mid-period border defense strategies and the rise of the general class.

Conclusion

Li Sheng's surprise raid on Tubo as a Right Army General was not only a milestone in his personal military career but also a microcosm of border warfare in the mid-Tang Dynasty. Combined with the grand narrative of the Zizhi Tongjian, this event helps readers understand more profoundly how Li Sheng grew from a border general into a famous minister of the restoration who saved the Tang Dynasty from crisis.
