In early 1912, this battalion received the commendation of the local government for the excellent and arduous duties performed in guarding extremist prisoners.

The Mishmi mission detachment returned at the end of February 1912, again with a commendation from His Majesty's Imperial Government for their excellent work.

In January of the same year, the Viceroy Lord Hardinge complimented the battalion and mounted escort for their smartness and remarked on the quality of the playing band.

Congratulatory messages were received from Lord Carmichael and Mr. Hughes Buller regarding the part the battalion had played in the fighting during the capture of Chenglong.

May wrote to the Inspector-General of Police with regard to the work of the battalion during the Dacca concentration: Two detachment camps were set up at Buxadar and Hoogly in 1914 with two new companies commissioned by the Secretary of the State for India.

The Battalion force was detailed for Law and Order duty in connection with the Komaghata Maru Sikhs Riots at Howrah and did excellent work in rounding up the rioters, and earning the thanks of the Governments of Punjab and Bengal.

On 22 April they engaged the Raiders;12 persons were killed and 29 police muskets and 2000 rounds of ammunition and many empty cases were recovered.

They were deployed whenever serious communal riots broke out and when the Civil Police found itself unable to suppress violent elements defying the authority of the state and endangering lives and property.

Before 1956 the duties performed by the Eastern Frontier Rifles Battalion were in connection with the communal troubles and border skirmishes within the state of West Bengal.

The government was reluctant to deploy the Army for various reason at the initial stages; on the other hand, they wanted a strong police action in the area.

In 1962, when India's border skirmishes with China developed into a war, the question of internal security came to the fore and once again attention went towards the Eastern Frontier Rifles and the 2nd Battalion, which is also stationed in Salua, was deployed to keep the peace in the state.

On 15 October 1911 Subedar Major Gopal Chandra with two havildars and ten sepoys attended the Delhi Darbar to receive medals.

In 1912, this battalion received a set of six bagpipes from Charles Bayley, Lieutenant-Governor of Eastern Bengal and Assam in recognition of their excellent services.

Whenever any state function is held in West Bengal, the services of this band party are requested to add colour to the occasion.

Naik Bachpan Lohar and Rifleman Anil Rava of the 1st Battalion represented West Bengal for the Agha Khan Gold Cup in 1977.

Shri Bir Bahadur Chhetri who represented India in the Olympic hockey tournament in 1976 and 1980 at Montreal and Moscow, respectively, was Lance Naik of this battalion.

Occasional cultural functions with traditional dances and music are organised in the battalion for the recreation of the Eastern Frontier Rifles personnel and their family members.

Recently tactical cum security training courses were conducted at the battalion for about 100 officers and men from the Rank of Dy.S.Ps to Havildars.

In February 2010 an EFR camp called Silda was attacked and burnt down by Maoist rebels, resulting in the loss of 24 riflemen out of a detachment of about fifty.

This resulted in condemnation of the state government by the EFR Special Inspector General, Benoy Chakraborty, who claimed his force was "miss-used" and "ill-treated".
