On 15th December 1948 Capt. D.D. Mistri was the Observation Officer of the forward most picquet, at Chhawa Ridge in the Naushera Sector where the enemies relentlessly shelled his position using every type of artillery from 3.7 howitzer to 5.5 mortar guns. In spite of this murderous fire, Capt Mistri stuck to his post, and it was due to his fearless conduct that the hostiles guns were pinpointed in that sector. He was also able to confirm the presence of enemy Sherman Tanks in the Sandoa village area and remained at his post when these tanks engaged his picquet for more than two hours. He would not listen to the entreaties of the platoon commander to seek safety but continued to observe and pass back the information to the guns. On one occasion more than a dozen shells straddled his O.P. but still undaunted he remained there till a 75mm shell hit his position killing him instantaneously. Captain Mistry was awarded Mahavir Chakra for his conspicuous courage and unparalleled gallantry posthumously.
