The building of this section allowed much-needed supplies to flow to the troops engaged in attacking the Japanese 18th Division, which was defending the northern area of Burma with their strongest forces around the towns of Kamaing, Mogaung, and Myitkyina. Before the Ledo road reached Shingbwiyang, Allied troops (the majority of whom were American-trained Chinese divisions of the X Force) had been totally dependent on supplies flown in over the Patkai Range. As the Japanese were forced to retreat south, the Ledo Road was extended. This was made considerably easier from Shingbwiyang by the presence of a fair weather road built by the Japanese, and the Ledo Road generally followed the Japanese trace. As the road was built, two fuel pipe lines were laid side-by-side so that fuel for the supply vehicles could be piped instead of trucked along the road.
