Rezang La[1] is a mountain pass on the Line of Actual Control between Indian-administered Ladakh and the Chinese-administered Spanggur Lake basin.

[3] The "C" Company of India's 13 Kumaon battalion, made of Ahir soldiers, fought to the last man in an effort to block the Chinese PLA troops from crossing the ridge into the Chushul Valley.

The battle was the last event of the Sino-Indian War, as the pass was the Chinese claim line and upon overrunning the ridge, a ceasefire was called.

The old survey maps of the region label two adjacent valleys leading to the Spaanggur Lake as "Rezang Lungpa".

The pass at the head of the eastern valley (33°23′20″N 78°55′44″E / 33.3888°N 78.9290°E / 33.3888; 78.9290 (Rezang La)), unlabelled in the survey map, is at a much higher elevation of 20,670 ft (6,300 m).

In 1963, the Government of India used the name "Rezang La" for pass marked on the survey map, the one at the head of the western valley.

[11] The Indian side was led by Major Shaitan Singh,[12] who perished in battle and posthumously won India's highest military decoration, the Param Vir Chakra, for his actions.

[24][25] The first four lines are quoted from Horatius, a poem by Thomas Babington Macaulay, member of the Governor-General of India's Supreme Council from 1834 to 1838[26] How can a man die better, Than facing fearful odds, For the ashes of his fathers, And the temples of his gods.

To the sacred memory of the heroes of Rezang-La 114 martyrs of 13 Kumaon who fought to the last man last round against hordes of Chinese on 18 November 1962.

Major-General Ian Cardozo writes in his book Param Vir, Our Heroes in Battle: When Rezang La was later revisited dead jawans were found in the trenches still holding on to their weapons... every single man of this company was found dead in his trench with several bullets or splinter wounds.

Raina lauded:[27] You rarely come across such example in the annals of world military history when braving such heavy odds, the men fought till the last bullet and the last man.

Annual memorial function is held by the Samiti in collaboration with district administration, the Kumaon Regiment and family members of those who died at Rezang La also participate.
