evidence: 2) However Professor Gangmumei in his article " The Lost Territory of Manipur: Cession of Kabaw Valley" published in "Manipur: Past and Present", Vol I, 1987, page 23, stated the Kabaw Valley proper is about 150 miles long and 8 miles breath and is situated between present Manipur Sector and Angoching hills adjacent to Chindwin River. In terms of area, he stated that the Valley lies between Manipur Sector of India boundary (i.e. West) and Western bank of Chingwin River (i.e. East); the South is the southern limit of Kule (Kale-present Kalwa) where Manipur river falls to Ningthe River (Chindwin). The Professor further adds that Kabaw Valley which is subject of dispute is much larger territory consisting of about 3000 sq. miles which is now a part of upper Chindwin District of Burma. It includes three Sub-divisions - Samjok, Khumbat and Kale. In ancient times it had three principalities - Samjok (Thandent), Khumbat (Khambat) and Kale (Present Kalewa). [...] iii) King Kiyamba (1467 - 1508) along with Pong King Sooloongkhum defeated the Raja of Khumbat, devided the captured territory and thus Kabaw Valley was annexed to Manipur in 1475. This is the common believe that Kabaw Valley was part of Manipur since 1475. This is an utterly wrong one propagated by half-heated historians.
