Major Puran Singh Bika of 13 Grenadiers (Ganga Risala) belonged to Bikaner in Rajasthan. During the 965 Indo-Pak war, Major Singh was commanding a long range border patrol in Rajasthan. During the early hours of 31 Oct 1965, he bumped into a strongly held and well dug in enemy position and some of his men were encircled by the enemy. Major Singh deployed his remaining men so that the enemy was himself almost encircled.

When the enemy opened heavy fire, Major Singh led his men and returned the fire so effectively that the enemy abandoned the position. He was also instrumental in foiling three successive enemy attacks on another position. Subsequently, he was killed in an enemy ambush.

Throughout, Major Puran Singh displayed exemplary courage and unflinching determination in the best traditions of the Indian Army. He was posthumosly awarded with Vee Chakra.

On 14th March 1976, the district authorities of Bikaner raised a statue of Major Puran Singh at Bikaner to perpetuate his memory. Earlier, in 1966, Gajner Road and a power house were named after him.
