During the Sino Indian conflict of 1962 a Sikh platoon commanded by Subedar Joginder Singh in Tawang sector, came under attack on the morning of 23rd October.

The first two attacks were beaten back, but the platoon lost half of its men and the commander was wounded in the high.

The third attack was the fiercest. The enemy came in waves. When their ammunition ran out Subedar Singh called out to his few remaining men to follow him and shouting the Sikh battle cry"Wahe Guruji ka Khalsa, Wahe Guruji ki Fateh" they charged the enemy with their bayonets and went down fighting. Subedar Joginder Singh was awarded the Param Vir Chakra for his inspiring courage and devotion to duty, posthumously.

Lance Naik Gurung was posthumously awarded the Mahavir Chakra for his courage and gallantry.
