Pangsau Pass

Pangsau Pass or Pan Saung Pass, in altitude, lies on the crest of the Patkai Hills on the India–Myanmar border. The pass offers one of the easiest routes into Burma from the Assam plains. It is named after the closest Burmese village, Pangsau, that lies 2 km beyond the pass to the east. To the east of Pangsau Pass, India's undisputed easternmost point "Chaukan Pass" lies and to the east of Vijaynagar in the Changlang district. During the 13th century, it was the frequently used route by Ahoms, a Shan tribe, for their arrival and settlement in Assam in India. The British in the late 19th century looked at the pass as a possible railway route from India to Myitkyina in north Burma through the Hukawng Valley, all of which were part of the British Empire at the time, but no railway was built. In the 19th century, British railway builders had surveyed the Pangsau Pass, which is high on the India-Burma border, on the Patkai crest, above Nampong, Arunachal Pradesh and Ledo, Tinsukia (part of Assam). They concluded that a track could be pushed through to Burma and down the Hukawng Valley. Although the proposal was dropped, the British prospected the Patkai Range for a road from Assam into northern Burma. British engineers had surveyed the route for a road for the first . During World War II the pass became famous because of the Stilwell Road (Ledo Road) connecting British India to Nationalist Chinese forces fighting the Japanese in China. The pass was the large initial obstacle encountered by United States General Joseph "Vinegar Joe" Stilwell's forces in their effort to build a land route to supplement The Hump air route (after the other land route, the Burma Road was lost to advancing Japanese forces). The Stilwell Road began at Ledo, Assam, the railhead, and passed through Tirap Gaon, Lekhapani, Tipong, Jagun, Jairampur (the Assam-Arunachal Pradesh boundary and beginning of Inner Line), and Nampong before switchbacking steeply upwards through densely forested hills to the pass, away. The distance from Ledo to Pangsau Pass is .
