During the Jammu & Kashmir operations in summer of 1948, Pakistani raiders mounted a strong counter offensive in the Tithwal sector. The enemy also forced the Indian Army to vacate their forward positions acrossriver Kishanganga. After the setback, Indian troops took position on the Tithwal ridge. At this juncture,6 Rajputana Rifles was moved from Uri to Tithwal to strengthen the 163 Bde in its impending offensive in the sector. The Indian offensive commenced on 11 July 1948. The operation went on well till July 15th. The recon reports, however, revealed that the enemy was holding a high feature in the area and that its capture was essential for making any further progress. Further ahead lay another feature also held in strength by the enemy.

The 6 Rajputana Rifles was assigned the task of securing these two features. The 'D' Company was to secure the first feature. The 'C' Company was to capture the second feature after the 'D' Company had carried out its task. The 'D' Company launched its attack on the objective at 0130 hrs on July 18th. The path to the objective was about one metre wide with deep ravines on either side. Overlooking this narrow path were the hidden enemy bunkers. The company was subjected to heavy fire and with half an hour it suffered 51 casualties.

During this battle, CHM Singh was with the leading section of the company, more than half of which was mowed down by the devastating fire of the enemy. He rushed forward to deal with the enemy medium machine gun post which was playing havoc with his troops. Enemy grenade splinters ripped open his clothes and wounded several parts of his body. But this did not deter him. He still continued the advance, shouting the battle cry, "Raja Ramchandra Ki Jai". Rushing forward he bayonetted the crew of the enemy MMG, with his own sten gun, silenced the menacing gun and occupied the post.

By this time all his companions lay behind either dead or wounded. The responsibility of clearing the enemy from the hill feature lay with him alone. Bleeding profusely he inched forward to attack the second enemy MMG post. At this juncture a grenade wounded him in the face. The blood dripping from his face almost blinded him. By now all the sten gun ammunition with him had been spent. He courageously crawled out of the occupied enemy trench and hurled grenades at the next enemy post. CHM Singh then jumped into another trench and bayonetted two enemy soldiers to death.

As CHM Singh, emerged out of the second trench to charge on the third enemy bunker, he was hit in head by a bullet and was seen dropping on the edge of the enemy trench. There was an explosion in the trench which showed that the grenade had done its work. By then CHM Piru Singh's wound had proved fatal.

"He paid with his life for his singularity brave act, but he left for the rest of his comrades a unique example of single-handed bravery and determined cold courage. The country is grateful," wrote Prime Minister Jawaharlal Nehru to Mrs. Tarawati, 75-year old mother of Company Havildar Major Piru Singh, "for this sacrifice made in the service of the Motherland, and it is our prayer that this may give you some peace and solace."
