Initially, Chinese troops were incorporated into the existing Manchu Banners. When Hong Taiji captured Yongping in 1629, a contingent of artillerymen surrendered to him. In 1631, these troops were organized into the so-called Old Han Army under the Chinese commander Tong Yangxing. These artillery units were used decisively to defeat Ming general Zu Dashou's forces at the siege of Dalinghe that same year. In 1636, Hong Taiji proclaimed the creation of the Qing dynasty.
