In reaction, the Japanese organized the Su Ping-wei Subjugation Campaign from November to December 1932. Nearly 30,000 Japanese and Manchukuo soldiers including the Japanese 14th Infantry Division and Mongol cavalrymen of the Manchukuo Hsingan Army directed a fierce campaign against Su and Ma's troops. On November 28, 1932, Japanese 14th division attacked Ma Zhanshan and Su Bingwen around Tsitsihar. Japanese planes bombed Ma Zhanshan's headquarters in Hailar. By December 3, the Japanese took Ma Zhanshan's Hailar headquarters. And the following day, after heavy fighting, Ma Zhanshan and Su Bingwen with the remnants of their forces fled Hailar for the Soviet border and entered Russian territory on December 5. Most of their troops were later transferred to Rehe.
