On 19 January 1942, two Japanese divisions invaded Burma and within five months defeated a numerically superior Allied Army. The Japanese conquest of Burma completely isolated China from lend-lease equipment support provided to it via the Burma Road. Over the course of the next three years, Allied forces engaged in ground campaigns designed to re-establish this land communications link with China. This is a description of the Allied campaigns in Burma and the importance that secure supply lines played in each of those campaigns. Information was gathered by historical review of a variety of reference materials. The lessons of Burma related to the campaigns launched there can be applied today in that country and in similar areas of operation around the world.
