Captain Dara Dinshaw Mistri was an observation Officer at the forward-most picket in Naushahra area during the Jammu and Kashmir operations of 1948. In December, Pakistani intruders seeking to capturer the base, subjected it to heavy shelling. But Captin Mistri refused to withdraw. He stuck to his post, conveying much needed information to the Indian units.

Frustrated by his stubborn stand, the enemy intensified the attack. The Pakistani Sherman tanks, whose presence he confirmed to the Indian soldiers, engaged his picket for more then two hours, but despite the battering, Captain Mistri would not budge. He stood at his postuntil he was struck by a 75-mm shell that killed him instantly.

For the awe-inspiring courage and sacrifice, Captain Mistri was posthumously honoured with the Mahavir Chakra.
