The battery was taken, the redoubt was surrendered after it, and then the main forces of Ibrahim Pasha cleared the position, having lost 1,500 men of lower ranks and officers prisoners, 37 banners/flags and 13 cannons.

Bringing his 4 battalions to them without a shot, Defrelden opened heavy fire on them and forced the Turks to clear the trenches and take refuge in the monastery of St. Spyridon, the thick stone walls of which gave them the opportunity to desperately resist.

In 1794 campaign in Poland, Derfelden was entrusted by Suvorov with the task of occupying Grodno and, covering the flank and rear of the main army's forces, to distract the Poles.

On the way, at the crossing of the Bug near the village of Pańków, he defeated a detachment of General Mokronowski, who was rushing to the aid of the capital, and, joining Suvorov's troops, took a valiant part in the storming of Praga, for which he was awarded the rank of general-in-chief.

In 1797 Derfelden was awarded the Order of St. Andrew, but soon after he was dismissed from the service and re-entered it in 1799, with the commission to accompany Grand Duke Konstantin Pavlovich to Suvorov's Italian army and to have the closest care of him there.

At the famous military council in the Muttental, Derfelden, universally respected for his fighting and personal qualities, had to speak on behalf of all his comrades in response to Suvorov's words.

Suvorov was touched by Derfelden's speech, and "moral connection between the troops and the leader was bonded and certified for life and death" (A. F. Petrushevsky).
