Khalkam was deported to Hazaribagh jail after British capture, where he committed suicide with his brother Lengpunga.
[1] Khalkam convinced his parents Sukpilal and Pibuk, to wage war on Lemkhama after the marriage of Tuali.
[4] To avenge the defeat Khalkam aided the British in the Lushai Expedition 1871 which was targetted against the Eastern chiefs.
[1] John Edgar, Deputy Commsioner of Cachar received a visit from Khalkam and described a path from Tipai Mukh which would make entry into the Lushai Hills for elephants more passable.
[5] The general stationed at Silchar felt that the posts established on the Sylhet-Cachar frontier was not sufficiently south to protect the right flank against Sukpilal and Khalkam if they united with the Eastern chiefs against the British.
[6] This decision to cooperate was made on the belief that the British would aid him in future attacks on the Eastern Lushai chiefs.
Khalkam was one of the few chiefs who did not meet with Major Boyd and Hari-Charan Sharma in their 1974 tour of the Lushai Hills.
[7] Khalkam subsequently recruited a mutineer, Rutton Singh, who escaped from Chittagong in the Sepoy Mutiny of 1857.
Rutton also held a strong anti-British view and carried out drownings of innocent women and children in the Dhaleswari, which affected Khalkam's reputation.
[8][10] In September 1877, Lemkham attacked Khalkam's settlements and carried off 15 heard to avenge the theft of salt from him.
In early 1878, Khalkam captured men from the eastern chiefs at salt springs in Lengvoi and attempted raids on his Sonai bazaar.
Khalkam opposed the idea of attacking the Eastern Lushai chiefs on the basis that he was in the middle of migrating his settlement for a new jhum plot and was unable to commit to another war.
[13] In March 1876 the traders and merchants at Sonai bazaar caught some thieves and sent them to Khalkam who seized the property of the perpetrators.
Despite consisting of 6 shops, the rubber in the Lushail Hills had been depleted from over harvesitng during the mautam famine and a fall in prices overall.
After some skirmishes between the eastern and western chiefs, Khalkam requested the British to move the Sonai bazaar 20 miles further.
The merchants at Sonai bazaar eventually left in January 1877 due to lack of profitability in the rubber trade.
[16] Khalkam committed himself to guarding the bazaar but the lack of profitability led to merchants closing their stalls and leaving.
[18] After Khalkam moved east of the Sonai river, the deputy commissioner on promises made by Lemkham and Poiboi reopened the bazaar.
[22] Khalkam's brothers, Lengpunga and Jarok also participated in the Chengri Valley raid which further aggravated British hostilities.
[21] This led to the British undertaking a punitive expedition with occupation of the Lushai Hills necessary to prevent raiding.
[32] During trial, Khalkam was found guilty of the murder of H.R Browne the first political officer of the North Lushai Hills.
We did not like this and subsequently when Leipung, a mantri of Lenkhunga told me (Khalkam’s deputation accused Changkunga chaprasi of giving the wrong information that excited the rising) that he had heard the Saheb was going to collect revenue from the Western Lushai first, and then from the Eastern Lushais and that we would not even be allowed liberty to hunt in the jungles.
A meeting was held in my Jolbuk (guest house) at which representatives from Thangula, Thanruma, Lenkhunga, Lalrihma, Minthang and Rankupa were present.Khalkam confessed on the assumption that nothing were to happen and that he would be able to return to his wife and family.
The justification for Khalkam's detention was provided on the basis that he and other chiefs were responsible for a rise in violence termed the "Western Lushai uprising".
