The British and American strategies in the CBI (China-Burma-India) theater were significantly different and with the difficult terrain, weather issues and disease; the challenges for the commanding general in Burma, Joseph Stillwell, were significant. Japanese forces had closed the Burma Road into China. The political differences among the Allies – the British, Americans and Chinese – meant there would be no offensive in 1942 nor spring of 1943, Finally in October 1943 American forces began to retake the Ledo Road, an action that would last until October 1943. The Allies did agree at the Quebec Conference in August 1943 to mount a dive in early 1944 to finally retake Burma, Long range penetration forces lead by the U.S. ‘Merrill’s Marauders’ began an advance in February 1944 eventually taking the key airfield at Mykena. The British stopped the Japanese drive into India in the summer of 1944 and went on the offensive in Burma and on January 28m 1945 the Burma Road was cleared into China and Burma retaken.
