The growing discontent with the Government ultimately resulted in a secessionist movement led by Mizo National Front (MNF), an organisation that had evolved out of a famine relief team.

MNA consisted of around 2000 men, supported by another group called the Mizo National Volunteers (MNV), which comprised an equal number of irregulars.

The extremist MNF leaders wanted to take advantage of this situation by starting an armed rebellion to establish an independent Mizo nation.

On the night of 27 February, Rokima, the brother of the MNF lieutenant Pu Lalnunmawia was killed in an apparently accidental blast, which was noticed by the AR personnel.

On the night of 28 February/1 March 1966, the MNF launched a series of simultaneous attacks on the 1 AR garrisons at Aizawl, Lunglei and Champhai and the 5 BSF posts at Chawngte, Demagiri, Hnahlan, Marpara, Tipaimukh, Tuipang, Tuipuibari, Vaphai and Vaseitlang.

According to a statement made by the Chief Minister of Assam Bimala Prasad Chaliha, on 1 March, the insurgents who attacked the Aizawl treasury and Lunglei numbered around 10,000.

Bimala Prasad Chaliha condemned Laldenga for his "betrayal", while Gulzari Lal Nanda promised "stern action" with "all the force" at the Government's command.

The IAF was asked to carry the troops in Mi-4 helicopters into the besieged AR camp, accompanied with fighter escorts, but failed due to heavy and accurate fire by the insurgents.

[11] On the afternoon of 4 March 1966, the IAF jet fighters strafed the MNF targets in Aizawl using machine guns, allegedly causing few civilian casualties.

[21] Two MLAs of the Assam state, Stanley DD Nichols Roy and Hoover H Hynniewta, visited the Mizo district to take a stock of the situation.

Inconsistent policies in the PPV, such as the stopping of the food ration system in 1968, increased prices of basic commodities such as rice and sugar, which further exacerbated starvation among the population.

One event submitted to the memorandum of the Human Rights Commission in Mizoram recounts in 1967 how the village of Hnahchang was set on fire and burnt down by the 3rd Bihar Regiment.

The bodies were placed within the sheds and burned down[34] In A Mizo Civil Servant's Random Reflections, an army members confession details the process for the village of Darzo.

The PPVs created were: Vairengte, Lungdai, Thingdawl, Kawnpui, Bilkhawthlir, Sihpir, Durtlang, Zemabawk, Tlungvel, Thingsulthliah, Pangzawl, Baktawng, Chhingchhip, Chhiahtlang, Serchhip, Bungtlang, Hnahthial and Zobawk.

[46] The administrative officer was also assigned two Gram Sevaks; a Pharmacist, Midwife and Health Assistant; Female Searcher; UDA and LDA clerks; five porters to work under him.

The other 39 NGCs were: Tuipuibari, Phuldungsei, Marpara, Darngawn, Puankhai, Kawnpui, Demagiri, Kalaichari, Borapansuri, Jarulchari, Vaseitlang, Parva, Lokicherra, Rengdil, Lungsei, Kawrtethawveng, Haurruang, Lawngtlai, Thingfal, Ruantlang, Bungzung, Vanzau, Tawipui, Zote, Ruallang, Saitual, Kawlkulh, Khawzawl, Champhai, Chawngtlai, Vaphai, Bungzung, Farkawn, Khawbung, Lungdar, North Vanlaiphai, Cherhlun, Khawlailung, Neihdawn.

Upon scrutiny by the Gauhati High Court to justify the continuation of the policy, the Government of Assam assured no further implementation of the operation which prevented the third and fourth phase from being carried out.

The dissolution of this strategic region and partnership crippled the insurgency's ability to evade government forces and be resupplied with weapons and resources to continue their fight.

As early as December 1972 upon the Independence of Bangladesh, the NEC under Malsawma Colney met with leader of the Union Territory of Mizoram to begin initiating talks with India.

[24] In 1975 the Assassination of Sheikh Mujibur Rahman and the subsequent junta government prompted laldenga and the MNF to re-establish bases in Bangladesh to evade Indian counter-insurgency.

[60] Following a series of meetings with RAW agents, Laldenga visited Delhi with his family in 1976 to begin the first official rounds of talk with the Government of India.

[24] Laldenga demanded Morarji to dismiss Sailo's cabinet and government and for him to be instated as chief of Mizoram under the claim he was the sole legitimate representative of the Mizo people.

it was further stated that effective measures of surrendering arms must be implemented before he can be assigned chief minister, or else no more talks will be made with Laldenga, citing lack of fulfilment.

Brigadier T. Sailo issued a strong warning to the Mizo National Front in an All India Radio Aizawl speech the following day.

Drunken MNF participants demanded his wife for him and executed him in forceful entry with an Ak 47 rifle and hung a Quit Mizoram notice in the room of the murder.

Desai was blamed for the arrest despite it being under Charan Singh's prime ministership.The political actors of the time described the imprisonment as a breach of faith for Laldenga coming to Delhi for peace talks.

Chief Minister Lal Thanhawla expressed cooperation for peace talks upon his inauguration, but this became severely delayed following the assassination of Indira Gandhi.

[64] Security officers, after the events of the MNF uprising, engaged in detainment of men, looting of property, mass rapes of women, unjustified killings and torture in settlements such as Kolasib and Kawnpui.

Officers of the Army would also abuse their power and demand women from village councils or engage in rape, which would-be underreported due to cultural stigma and shame.

[65] The grouping policies of Operation Accomplishment oversaw the settlement of Protected and Progressive Villages (PPV), which unfolded many human rights violations and abuses.
