According to historical records, Nurhachi was still alive and kicking after the victory in Ningjin. After this war, Nurhachi still fought everywhere, fighting everywhere, without any injuries. Although it is recorded that Nurhachi went to the hot springs before his death, he went to the hot springs not because of injuries, but for recuperation.
Nurhachi died a long time ago in Ningjin. Nurhachi was sixty-eight years old when he officially died, which was a rare thing in ancient times. Nurhachi died half a year after Ningjin's victory. It really doesn't make sense to regard the victory of Ningjin as the cause of death of Nurhachi.
The triumph of Ningjin gave Yuan Chonghuan an illusion. Because of the victory of Ningjin, the rulers of the Ming Dynasty really breathed a sigh of relief, which made Yuan Chonghuan have an illusion that the latter Jin was not invincible, and they could defeat the latter Jin in the Ming Dynasty. So after the victory of Ningjin, Yuan Chonghuan was sent to Liaodong. However, if we look at the fighting nature of Ningjin's victory, this is a wrong decision.
Because Ningjin's triumph was not smooth. Daming suffered heavy casualties in the battle of Ningjin. Although the Ming army won in the end, it was the Ming army that suffered the most casualties and was used in the war? Wall gun? This is still the last resort. But in some people's eyes, it was Yuan Chonghuan who guided us well, and it was Yuan Chonghuan who led us to victory. Therefore, Wei Zhongxian began to reuse Yuan Chonghuan. In the future, Daming will fully support Yuan Chonghuan as long as it is the war led by Yuan Chonghuan.
