Hao relinquished his command in 1937 after battling communist forces for decades, but returned after the
Marco Polo Bridge Incident. By the time he got back to the front line from
Sichuan, the IJA had already broken through
Yanmen Pass and were converging on
Xinkou. Under
Wei Lihuang's 14th Army Group, Hao led his 9th Army and
Shanxi clique's 19th, 35th and 61st Armies in the defense of Xinkou. == References ==
