The Jisi Incident (simplified Chinese: 己巳之变; traditional Chinese: 己巳之變) was a military conflict between the Later Jin dynasty and the Ming dynasty, named because it happened in 1629, a jisi year according to the Chinese sexagenary cycle. In the winter of 1629 Hong Taiji bypassed Ming's northeastern defenses by breaching the Great Wall of China west of the Shanhai Pass and reached the outskirts of Beijing before being repelled by reinforcements from Shanhai Pass. The Later Jin secured large amounts of war material by looting the region around Beijing. This was the first time Later Jin forces had broken through the Great Wall since they rose up against the Ming dynasty.[1]
