He died at Siva Stena during the Battle of Kaymakchalan while commanding the 2nd Volunteer Battalion. The battle was fought between 12 and 30 September 1916, when the Serbian army managed to capture the peak of Prophet Ilija while pushing the Bulgarians towards the town of Mariovo. His courage was on display when he single-handedly charged a machinegun nest, receiving a bullet wound in the head. After receiving a second wound in the head, he fell unconscious, and as soon as he came to, Pantić urged his men to leave their cover and counterattack by yelling the famous words, "Go! We have to take the position even if we all have to die!" His men overpowered the enemy post and took the high ground.
