Lieutenant Bihari Singh was an officer of the Indian Army's Rajput Regiment who served with 4 Rajput during the 1965 Indo-Pakistan War. He was born on 5 January 1938 and hailed from Ranipur village in the Muhammadabad Gohna area of Mau district, Uttar Pradesh.
He was commissioned into 4 Rajput as a Second Lieutenant and subsequently rose to the rank of Lieutenant. In May 1965, 4 Rajput was deployed in the Kargil sector under 121 Infantry Brigade. The battalion was assigned the task of capturing strategically important heights, including Point 13620, which overlooked the Srinagar–Leh road.
During the assault on Point 13620 on 17 May 1965, Lieutenant Bihari Singh led a platoon towards the enemy position over difficult mountainous terrain. His platoon came under intense enemy fire from mortars, machine guns and small arms. He continued to lead from the front and took part in the assault and capture of the first peak of the objective.
Lieutenant Bihari Singh sustained severe injuries during the engagement. He was evacuated for medical treatment but succumbed to his injuries on 23 September 1965. He was subsequently remembered in his native area, where a memorial was established in his honour.
