On 9 April 1945 near Fusignano, Italy, at the start of the Allied spring 1945 offensive Haidar's battalion was tasked with a difficult assault crossing of the Senio River. Only Sepoy Ali Haidar and the two other men of his section managed to get across under heavy machine-gun fire. Then, Without orders, and on his own initiative, Sepoy Ali Haidar, leaving the other two to cover him, charged the nearest post which was about 30 yards away. He threw a grenade and almost at the same time the enemy threw one at him, wounding him severely in the back. In spite of this he kept on and the enemy post was destroyed and four of the enemy surrendered. With utter disregard of his own wounds he continued and charged the next post in which the enemy had one Spandau and three automatics, which were still very active and preventing movement on both banks. He was again wounded, this time in the right leg and right arm. Although weakened by loss of blood, with great determination Sepoy Ali Haidar crawled closer and in a final effort raised himself from the ground, threw a grenade, and charged into the second enemy post. Two enemy were wounded and the remaining two surrendered.
