The Battle of Ningyuan was a battle between the Ming Dynasty and the Manchurian Later Jin in 1626. The Ming won this battle. This battle marked the temporary resurgence of the Imperial Ming army after a long series of defeats. Before 1626, the Imperial Ming army had been very badly defeated by the Manchus. Part of the Imperial Ming army's new strategy of defense after defeat was to develop Ningyuan into a military stronghold. Yuan Chonghuan, with the support of Sun Chengzong, was seriously strengthening the defense of Ningyuan in anticipation of a Manchu attack. After Sun Chengzong was replaced by a new commander, the new commander ordered all Ming Forces outside the Great Wall to retreat inside and abandon all land outside Shanhai Pass. Yuan Chonghuan objected stronglly and was thus left to command a lone army guarding Ningyuan. In 1626 Kundulun Khan Nurhaci, seeing all Ming forces leaving, decided to advance towards Ningyuan, personally leading a force of 100,000-130,000. Wikipedia [ - ]
