李寿
On December 24, 1935, General Minami sent two battalions of irregular Manchurian cavalry under Li Shou-hsin, a squadron of Japanese planes, and a few tanks to assist Prince Demchugdongrub in occupying the northern part of Chahar province. The six hsien's of northern Chahar, were defended by only a few thousand men of the Peace Preservation Corps. With Li's assistance the Inner Mongolian forces soon overran the area.
