The other day, Sela tunnel was inaugurated by PM.
But do we all know that not only Sela but the entire Arunachal (formerly NEFA) wouldn't have been part of India but courtesy Shri Jayram Daulatram, Governor of Assam 1949-56, and the efforts of Maj Bob Kathing who won the entire state with only 200 men.
And see the tragedy- when they proudly went to disclose this to Nehru (expecting a 'Shabaash'), he became furious, gave a dressing to both and told them to get out.
