Due to Chiang Kai-shek's policy of non-resistance, the Japanese were soon able to establish complete control.After the League of Nations refused to do more than voice its disapproval, there were many small guerrilla organizations which resisted Japanese and Manchurian rule: Besides these armies there were other forces under leaders like Zhang Haitian and others.Gen. Ma Zhanshan, nominally in command of them all, had a total fighting force estimated by the Japanese at 300,000 men.Ongoing Japanese "Anti-Bandit" campaigns and other "pacification" measures steadily reduced the number of insurgents.From 1935 the Northeast Counter-Japanese United Army, under the leadership of the Chinese Communist Party, absorbed many of these volunteer forces into its own ranks.
