Li Guangyan

In 806, during the reign of Emperor Dezong's grandson Emperor Xianzong, Yang Huilin (楊惠琳) seized control of Xiasui Circuit (夏綏, headquartered in modern Yulin, Shaanxi), and Emperor Xianzong mobilized the armies of Hedong and Tiande Base (天德軍, in modern Bayan Nur, Inner Mongolia) to attack Yang. Yan Shou (嚴綬) the military governor of Hedong sent Ädiz Guangjin and Ädiz Guangyan to attack Yang. Soon, Yang's subordinate Zhang Chengjin (張承金) killed Yang and surrendered.[5]

In the fall, Ädiz Guangyan was ordered to rendezvous with the army commanded by the general Gao Chongwen in attacking the rebel warlord Liu Pi, who had seized control of Xichuan Circuit (西川, headquartered in modern Chengdu, Sichuan). Ädiz Guangyan was late for the rendezvous by one day, and feared punishment. He thus advanced behind Liu's lines at Lutou Pass (鹿頭關, in modern Deyang, Sichuan) and cut off Lutou Pass's supply route and led to its surrender to Gao.[5] It was said that Ädiz Guangyan became famous due to this battle, and he was later successively made the prefect of Dai (代州, in modern Xinzhou, Shanxi) and Ming Prefecture (洺州, in modern Handan, Hebei).[1]

In 811, Emperor Xianzong bestowed the imperial surname of Li on Ädiz Guangjin, then the military governor of Zhenwu Circuit (振武, headquartered in modern Hohhot, Inner Mongolia) — and therefore, the Ädiz brothers were renamed Li.[6]

In 814, with Emperor Xianzong preparing a campaign against the rebel Zhangyi Circuit (彰義, headquartered in modern Zhumadian, Henan), whose military governor Wu Shaoyang had just died and Wu Shaoyang's son Wu Yuanji had just seized the control of without imperial approval, Li Guangyan was moved from Ming Prefecture to be the prefect of Chen Prefecture (陳州, in modern Zhoukou, Henan), as part of a number of movements of generals in preparation for the campaign. Li Guangyan was also made the commander of the forces of Zhongwu Circuit (忠武, headquartered in modern Xuchang, Henan), to which Chen Prefecture belonged to. Later that year, after Wu Yuanji openly rebelled, Li was made the military governor of Zhongwu, serving under his old commander Yan, who was put in charge of the operations against Zhangyi. Almost alone among the imperial generals against Zhangyi, Li had repeated success against Zhangyi troops, and when Emperor Xianzong sent the official Pei Du to the front to review the troops in 815, Pei's report to Emperor Xianzong singled Li out as brave and righteous in his behavior. However, while often victorious, he was not always so, and he suffered a defeat in fall 815 at Shiqu (時曲, in modern Luohe, Henan).[7]

Meanwhile, Emperor Xianzong, seeing Yan as an ineffective overall commander, put Han Hong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan) in overall command of the forces. However, it was said that Han, who liked having authority, did not want Wu to be destroyed too quickly and disliked Li for his fervent campaigning. In order to subvert Li, Han found a beautiful woman who he had trained in singing, dancing, music and the game of Liubo, and dressed in fine clothes and luxurious jewels. He had his messenger deliver the woman to Li as a gift, in the hope that she would distract him from his military activities. When Han's messenger delivered the woman to Li at a grand feast, it was said that all of the guests were astonished by her beauty. However, Li responded to the messenger:[7]

I am greatly grateful that the Lord Chancellor [(i.e., Han, who carried an honorary chancellor title)] had mercy on me, who is alone in this army. However, of the tens of thousands of soldiers here, who did not leave his home and his family, to come a long distance to subject his body to the sword? How can I just entertain myself?

He wept, as did the other guests. He then presented Han's messenger with gifts of his own for Han, and had the messenger deliver his gifts, along with the woman, back to Han, commenting, "Please thank the Lord Chancellor for me, Li Guangyan. I have promised the body to the empire, and I will not bear the sun or the moon together with the bandit [(i.e., Wu)]; I would rather die first."[7]

There was another incident in which Li came in conflict with Han. On an occasion Han ordered a general attack against a Zhangyi city, the Zhangyi forces responded by concentrating a counterattack against Li's colleague Wu Chongyin, the military governor of Heyang Circuit (河陽, headquartered in modern Pingdingshan, Henan), and the attack was so fierce that Wu Chongyin was hit by spears several times. He sought immediate aid from Li, and Li sent his officers Tian Ying (田穎) and Song Chaoyin (宋朝隱) to attack the Zhangyi forces from behind. After Tian and Song were successful, the attack against Wu Chongyin was terminated. However, as Li violated Han's orders in doing so, Han had Tian and Song arrested and was ready to execute them. Li, fearing Han, did not dare to intercede directly, but the imperial eunuch Jing Zhongxin (景忠信) happened to be present, and falsely ordered, in Emperor Xianzong's name, that Tian and Song be spared, before submitting a report to Emperor Xianzong as to what happened. Both Li and Han subsequently submitted conflicting reports, and Emperor Xianzong spared Tian and Song over Han's objections.[1]

Thereafter, Li and Wu Chongyin were repeatedly defeating Zhangyi troops, but there was no decisive victory.[7] In summer 817, when Li attacked the important Zhangyi city of Yancheng (郾城, in modern Luohe), the defender of Yancheng, Deng Huaijin (鄧懷金) offered to surrender to Li — but as Deng's and his soldiers' families were all at Zhangyi's capital prefecture Cai Prefecture (蔡州), Deng requested that he first be allowed to summon a relief army, and that Li then attack the relief army, before Deng would surrender, in hopes that Wu Yuanji would spare Deng's and his soldiers' families. Li agreed, and he subsequently defeated a Zhangyi army sent to relieve Yancheng, and Deng then surrendered. Wu Yuanji, in fear of continued advances by Li, sent his strongest soldiers, under Dong Chongzhi (董重質), to be stationed at Huiqu (洄曲, in modern Luohe), to try to defend against a probable Li attack.[8]

Meanwhile, Emperor Xianzong had commissioned Pei to oversee the operations against Zhangyi, and when Pei arrived at the front, he made Yancheng his headquarters. There was an occasion when Pei was overseeing the construction of the fortress of Tuokou (沱口, in modern Luohe), when Dong launched a surprise attack, almost capturing Pei. The Zhangyi forces were fought off by Li and Tian Bu, however, allowing Pei to escape capture — as it was said that Li foresaw a potential surprise attack by Dong and therefore had stationed Tian nearby.[8] With the Zhangyi forces concentrated on defending against Li Guangyan, Cai Prefecture was left relatively unguarded, and later in the year, Li Su the military governor of Tangsuideng Circuit (唐隨鄧, also headquartered in modern Zhumadian) was able to launch a surprise attack on Cai Prefecture, capturing Wu Yuanji.[1] With Cai Prefecture having fallen and Dong having fled back to Cai Prefecture to surrender to Li Su, Li Guangyan entered Dong's camp and accepted the Zhangyi soldiers' surrender there.[8] For his contributions, Li Guangyan was given the title of acting Sikong (司空, one of the Three Excellencies). In spring 818, Emperor Xianzong had a eunuch hold a feast for him at the eunuch's mansion and gave him a large award of rice. Emperor Xianzong also personally welcomed Li Guangyan and awarded him a golden belt and multicolored banners.[1]

In summer 818, in preparation for the campaign against another warlord, Li Shidao the military governor of Pinglu Circuit (平盧, headquartered in modern Tai'an, Shandong), Emperor Xianzong moved Li Guangyan to be the military governor of Yicheng Circuit (義成, headquartered in Anyang, Henan).[8] He was permitted to take some Zhongwu troops with him, and he subsequently, as part of the campaign against Li Shidao, defeated Pinglu forces at Puyang (濮陽, in modern Puyang, Henan). However, subsequently, Emperor Xianzong came to believe that Zhongwu and Yicheng forces should not be mixed, and therefore returned Li Guangyan to Zhongwu.[3]

In 819, during a Tufan incursion, Li Guangyan was moved to be the military governor of Binning Circuit (邠寧, headquartered in modern Xianyang, Shaanxi) and permitted to take 6,000 Zhongwu soldiers with him. He was also put in charge of reconstructing Yan Prefecture (鹽州, in modern Yulin).[1] At that time, the chancellor Huangfu Bo, whom Emperor Xianzong trusted, was in charge of the finances, and was not prompt in delivering supplies to the border defense troops. Worse, the supplies that he delivered were said to be so decrepit that the food could not be eaten and the clothes could not be worn; the soldiers were so angry that it was often rumored that mutinies would occur. Li was said to be so distressed that he considered committing suicide, as his petitions to Emperor Xianzong on the subject were not believed.[9]
