Later Tang conquest of Former Shu

The Later Tang conquest of Former Shu (后唐灭前蜀) was the campaign of 925 (同光三年) in which Later Tang, under Emperor Zhuangzong (Zhuangzong (庄宗)), destroyed the Shu regime in Sichuan: Prince Wei Li Jiji (李继岌) and the military commissioner Guo Chongtao (郭崇韬) led the army, and the Shu ruler Wang Yan (王衍) surrendered and was sent toward Luoyang with his clan and officials.¹ Within months of the victory the campaign's commanders were dead and Later Tang itself was collapsing.

Background and causes

Former Shu had been ruled by Wang Yan at Chengdu; the Song-era chronicle Shujian (蜀鉴) counts the regime's life from Wang Jian (王建)'s entry into Langzhou (阆州) in the Guangqi era to its fall in 925 as thirty-nine years.⁴ According to the Old History of the Five Dynasties (卷33), Emperor Zhuangzong ordered the conquest in 925: on a xinchou day (辛丑) he named Li Jiji as supreme commander of the armies, with Guo Chongtao as chief campaign director, entrusting all military arrangements to Chongtao.⁵ The court context was strained: the record of the period sets the decision against factional strife at Zhuangzong's court, in which Chongtao was already being squeezed by the palace eunuchs.⁶

Course of events

The advance. The Tang army entered the passes through Dasanguan (大散关); Wang Chengjie (王承捷) surrendered with 12,000 men and 400,000 in military stores, and the army took Sanquan (三泉) with more than 300,000 in stores, after which the army wanted for nothing and its reputation surged.⁵ On a wuxu day Li Shaochen reached Lizhou (利州) and built a pontoon bridge at the Jubei crossing; the Shu military governor Lin Si'e (林思谔), who had already abandoned his city for Langzhou, sent envoys to surrender.¹ On a jiachen day Prince Li Jiji reached Jianzhou (剑州), and the Shu military governor Wang Zongshou (王宗寿) surrendered five prefectures.¹

The collapse of the Shu court. On a jiyou day Li Jiji reached Mianzhou (绵州); the Shu ruler had the academician Li Hao (李昊) draft a surrender memorial and the chancellor Wang Kai (王锴) draft the surrender letter, and sent the vice minister Ouyang Bin (欧阳彬) to present them.¹ Wang Chengxiu (王承休) and Wang Zongrui (王宗汭) were executed at Chengdu with their sons.¹

Conduct of the fighting

The campaign was decided less by set battles than by speed and defection: Shu governors and commandants surrendered city after city, bringing their troops and grain stores with them, so that the invaders fed themselves from captured magazines such as the 400,000 in military stores at Wang Chengjie's submission.^{5 • 7} Command was lopsided: although Li Jiji held the title of supreme commander, every appointment and arrangement in the army came from Guo Chongtao, who spent his days deciding affairs while the prince's own headquarters stood empty.¹

Outcome

The spoils became a court quarrel: when Zhuangzong read the Shu treasury registers and asked why the fabled wealth of Shu seemed so slight, the eunuch Xiang Yansi (向延嗣) told him the treasures had gone into the hands of Chongtao and his son, who were said to hold 10,000 taels of gold, 400,000 taels of silver, a million strings of cash, and a thousand fine horses.¹ Shujian preserves a different inventory said to have been reported from Shu: 300,000 soldiers, nearly 1,500 horses, 2,530,000 shi of grain, and 1,920,000 strings of cash, figures far above the Tongjian's.⁴ In the first month of 926 (天成元年) the prince sent Wang Yan, his clan, and several thousand officials toward Luoyang under escort.¹ The prince also presented more than two hundred Shu court musicians to the throne.¹

Political influence

The conquest destroyed Former Shu but broke the victor's court. The emperor, already resentful that Shu people had asked for Chongtao as their governor, sent Meng Zhixiang west with instructions to kill him if investigation confirmed disloyalty.¹ On a jiazi day at dawn in 926, Li Congxi summoned Chongtao on the prince's orders and the prince's attendant Li Huan (李环) smashed his skull on the stairs, killing his sons Guo Tinghui (郭廷诲) and Guo Tingxin (郭廷信) with him; the staff officer Li Song (李崧) then forged an imperial edict, sealed in wax, to quiet the army.¹ The purge spread: the former general Zhu Youqian (朱友谦) was accused with Chongtao, transferred, surrounded at his house by troops, and killed, and his family and seven former subordinates then serving as prefects were exterminated; his wife showed the executing officer the iron certificate of immunity the emperor had granted the year before.¹ With the two great commanders destroyed, actors and eunuchs dominated the court and veteran officers could not feel safe; Li Siyuan (李嗣源) himself was repeatedly in danger and survived only through the protection of the palace commissioner Li Shaohong (李绍宏).¹ Mutiny followed: the army at Yedou (邺都) rebelled, repeated assaults failed, the court pressed Li Jiji to hurry east, and the prince, whose picked central-army troops were away under Ren Huan, was stuck at Lizhou.¹ In Shu itself, Meng Zhixiang, installed on Chongtao's earlier recommendation, appointed honest officials to the prefectures and counties, abolished arbitrary taxes, settled the displaced, and issued an edict of broad amnesty while exterminating the bandit bands that had filled the hills.¹

Assessment and disputed points

The standard narrative presents the campaign as a triumph of planning and speed, one that helped bring down Zhuangzong's government.^{2 • 1} Several numbers are disputed between sources. The length of Former Shu is counted by Shujian as thirty-nine years from Wang Jian's occupation of Shu in the Guangqi era.⁴
