He was a firm believer in the autonomy or independence of the Manchu, Mongol, and Lu (Han Chinese people from Shandong) peoples. He led 4,000 troops from Manchuria to Shandong in 1937, using his connections to transfer himself to Shandong. He took over
Jinan and used it as his headquarters as the "King" of Shandong. He advised many bandit units in the Jehol campaign. He created the
Shandong Autonomy Allied Army in 1938 under the orders of General
Terauchi Hisaichi. In late January 1939, he led a massacre in Ye County (today known as
Laizhou), killing around 400 people. This was known as the
Yexian (Ye County) Incident, and led to the dissolution of Date's unit in 1940. In 1945, Date tried to organize a unit called the Zhang Zongyuan Unit, but his attempt was unsuccessful and the unit failed quickly. After the
surrender of Japan at the end of World War II, Date was arrested for war crimes. He was held in the
Qingdao Detention Center and moved to the
Shanghai Temporary War Criminal Detention Center. He was sentenced to death, and Date was moved to
Shanghai Prison, where he was executed by firing squad on September 9, 1948. == References ==
