There was no freedom movement here in the national sense, and it would be a fabrication to describe one. There was no Congress committee, no newspaper, no Gandhian campaign, no electorate and no representation; the Inner Line of 1873 kept the colonial administration out of the hills and Indian political organisation out with it. What this region has instead is resistance to entry — four armed confrontations between 1858 and 1912, fought village by village over concrete grievances such as forced porterage, seizure of supplies, and interference with the trade the hills depended on, rather than for any national idea. The people below fought a frontier administration rather than an empire, and are best read that way. The record also preserves almost no names: one man is remembered in detail because the British tried him, and the several hundred who fought at Kekar Monying are not individually recorded at all. That silence is itself part of the finding.
Bitbor Mimak and Bongal Mimak1858 and 1859
The first two armed confrontations with British columns entering the Abor hills from the plain. They are known on the Adi side by these names; the surviving accounts of them are brief on both sides and the detail is thin.
Outcome: British entry into the hills was not sustained, and no administration followed.
Nijom Mimak1894
A further British expedition into the Abor hills, met with armed resistance. As with the earlier two, the Adi name for it has survived better than the operational record.
Outcome: The hills remained outside administration; the Inner Line of 1873 continued to be the working boundary.
Poju Mimak — the Abor Expedition of 1911–12October 1911 – April 1912
After the killing of Noel Williamson and Dr Gregorson on 31 March 1911, a large force with Gurkha infantry, sappers and survey parties moved up the Siang. Villages including Kebang and Rotung were attacked and burnt. Adi fighters held the cliff of Kekar Monying above the river against the advance, and an ambush mounted by Kebang and allied villages was met with machine-gun fire with heavy loss on the Adi side.
Outcome: The expedition ended in April 1912. Matmur Jamoh was tried and transported to the Andamans; the eastern frontier was reorganised as the Sadiya Frontier Tract; and the survey carried out during the operation supplied the mapping for the boundary alignment agreed at Simla in 1914.
