《宋金风云录》E4 宋朝唯一一次收复燕云十六州：宣和伐辽（1）The Song Dynasty regained Yanyun Sixteen States for the only time

宣和四年四月，宋徽宗命童贯以河北河东宣抚使勒兵十万巡边。同时任命保静军节度使种师道为都统制，武泰军承宣使王禀、华州观察使杨可世为之副。随后辽宋之间最后一次大型战役：宣和伐辽爆发。宋军因各种原因，全军大败。宋朝经营百年的西军遭到毁灭性打击，对金屡战屡败的辽国却在对宋战争中找回了点面子。
In April of the fourth year of Xuanhe, Song Huizong ordered Tong Guan to patrol the border with 100,000 Xuanfu envoys in Hedong, Hebei. At the same time, the Jiedu envoy of Baojing Army, Zhong Shidao, was appointed as the capital commander, and the Xuan envoy of Wutai Army, Wang Zhi, and the observation envoy of Huazhou, Yang Keshi, were his deputy. Then the last major battle between Liao and Song: Xuanhe and Liao broke out. Due to various reasons, the Song army was defeated. The Western Army, which had operated for a hundred years in the Song Dynasty, suffered a devastating blow, but the Liao Kingdom, which had been defeated repeatedly against the Jin Dynasty, regained some face in the war against the Song Dynasty.
