李希烈
In spring 783, Li Xilie finally took more apparent provocative action against the imperial government, by capturing Ru Prefecture (汝州, in modern Luoyang, Henan) and its acting prefect Li Yuanping (). He then sent his forces to raid the nearby prefectures. At the suggestion of Lu Qi — who had been resentful of the senior official Yan Zhenqing — Emperor Dezong sent Yan to Huaixi to make one final attempt to persuade Li Xilie to return to the imperial fold. Once Yan arrived at Huaixi, Li Xilie put him under house arrest, albeit at a comfortable pavilion, and refused his demands that Li Xilie return to the imperial fold. Li Xilie cut off the communication lines between Chang'an and the Yangtze River-Huai River region, forcing Tang official communications to go through the middle Yangtze region. HIs subsequent attempts to expand, however, were repelled by Tang generals Geshu Yao () and Li Gao () the Prince of Cao, and his campaign stalled. An attempt by his subordinate Zhou Zeng () to overthrow him and replace him with Yan, however, failed. In light of Zhou's failure, however, Li Xilie made one attempt to reconcile with Emperor Dezong, sending an apology that blamed his own rebellion on Zhou, and then moving his headquarters back to Cai Prefecture, where he felt more secure. For the next several months, he continued to engage imperial troops and raid the surrounding prefectures, but did not undertake any substantial maneuvers to expand.
