On 30 September Praporgescu took command of the 1st Army Corps, and participated in several of the skirmishes preceding the Battle of the Southern Carpathians. His 20th Division remained a part of the 1st Army, joining the other two divisions of the 1st Army Corps. By his actions, he infused new courage and energy into his subordinates. On October 13, 1916, during an engagement at the Turnu Roșu Pass, he went to inspect the troops in the Coți Mountains, at the western end of the Făgăraș Mountains, up from Câinenii Mici. While there, he was mortally wounded in the chest by a shrapnel from a stray artillery shell. He was buried three days later at Bellu Cemetery, in Bucharest.
