James Douglas vs Li Guangbi

Douglas led a daring night assault on Roxburgh Castle, scaling the walls with rope ladders. The capture of this key English-held fortress was a major victory for Robert the Bruce during the Scottish Wars of Independence.

Douglas commanded a division of the Scottish army at Bannockburn, where Robert the Bruce defeated Edward II's English forces. His leadership contributed to the decisive Scottish victory that secured Scottish independence.

Douglas led a devastating raid into northern England, burning towns and villages in Weardale. The raid forced the English to negotiate the Treaty of Edinburgh

Douglas carried the embalmed heart of Robert the Bruce on a crusade to Spain, fulfilling Bruce's dying wish. He died in battle against the Moors at Teba, throwing the heart forward before being killed.

Li Guangbi was appointed military governor of Shuofang, a key frontier command. He was of Khitan origin but loyal to Tang, and he began organizing defenses against the An Lushan Rebellion.

Li Guangbi defeated a Yan army at Jiayuguan (in modern Gansu), securing the northwestern frontier. This victory prevented the rebellion from spreading to the Silk Road regions and bought time for Tang counterattacks.

Li Guangbi led a campaign to recapture Taiyuan from Yan forces. Using a combination of siege tactics and cavalry raids, he retook the city, a major logistical center, and inflicted heavy casualties on the enemy.

Li Guangbi's forces were defeated by Shi Siming at Yancheng. The loss forced him to retreat and regroup, but he avoided total destruction and continued to harass Yan supply lines.

Li Guangbi played a key role in the final campaigns against Shi Chaoyi, the last Yan emperor. He coordinated with Uyghur allies and Tang forces to crush the rebellion, leading to its end in 763.
