The Allies had mixed success in mainland Asia. In March 1944, the Japanese launched the first of two invasions, an operation against Allied positions in Assam, India, and soon besieged Commonwealth positions at Imphal and Kohima. In May 1944, British and Indian forces mounted a counter-offensive that drove Japanese troops back to Burma by July, and Chinese forces that had invaded northern Burma in late 1943 besieged Japanese troops in Myitkyina. The second Japanese invasion of China aimed to destroy China's main fighting forces, secure railways between Japanese-held territory and capture Allied airfields. By June, the Japanese had conquered the province of Henan and begun a new attack on Changsha.
