World War I
At the onset of the Romanian Campaign of World War I, Praporgescu was named commander of the 20th Infantry Division, which was part of the Romanian 1st Army, under the command of General Ioan Culcer. The campaign started on 27 August 1916 with the Battle of Transylvania. After the Romanian forces launched an offensive towards Sibiu and defeated the defending Austro-Hungarian troops, a counter-offensive was launched by the 9th German Army under the command of Erich von Falkenhayn. From 26–29 September Praporgescu's troops, including those of the 23rd Division under the command of Colonel Traian Moșoiu, fought tenaciously in the Olt and Topolog valleys, blocking an attempted breakthrough by the Bavarian Alpenkorps. 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.
