In the spring of 1944, Japanese 15th Army was shattered at Imphal and Kohima, allowing General William Slim, commander of 14th Army, to liberate Burma overland from India - a task considered impossible by the British chiefs of staff. Overcoming immense logistical problems, Slim coordinated a precisely timed attack along a 200-mile front, the longest opposed river crossing of the entire war, and an armored dash behind enemy lines that seized Meiktila, cutting Japanese supply lines. Mandalay fell and at the end of March 1945, with the battle lost, the Japanese withdrew south. Slim gave them no chance; Allied troops raced south and captured Rangoon. The Japanese army in Burma was finished.
