On 08.09.1914, at the beginning of World War I, mobilized in Wadowice as a chaplain of the Army of the Austro–Hungarian Monarchy.

Throughout the war served in the 56th Galician Infantry Regiment (Germ. Galizisches Infanterieregiment Nr 56), known as the „Jack's Regiment”, with headquarters in Kraków and a recruiting district in Wadowice, of which 88% were Poles, as part of the 23rd Infantry Brigade belonging to the 12th Infantry Division — i.a. in the 3rd Battalion. In 1914‐1915, the regiment took part in fighting on the Galician front. Defended positions near the village of Przysłup not far from Gorlice. In 05.1915 took part in the victorious Battle of Gorlice, which led to the expulsion of Russian troops far to the east, beyond the borders of the pre‐war Austro–Hungarian Empire.

His personal fate is not clear. Prob. after mobilization was released home, remaining at the disposal of the military authorities. Prob. began his service proper in 01.1915. Prob. took part in the Galician battles. Next, however, was supposed to receive an order to report to the city of Prożoń (i.e. prob. Bratislava). As a result, transferred with one of the units of his regiment to the Serbian front (the unit was subordinated to another higher unit — his parent regiment did not formally fight there). There, in 10‐11.1915, the so‐called the second Serbian campaign, during which German–Austrian–Bulgarian troops defeated the Serbian army, took place. In the memory of the Poles, the Serbs „grabbed them by the neck and cut them to pieces”. In 1916 served during the battles near Dubna in Volyn, defending Austro–Hungarian positions on the Dniester River — prob. during the so‐called Brusilov Offensive. In 1917 his regiment fought, among others, near the town of Iacobeni near Suceava in Bukovina, after which it was transferred to the Italian front, where it took part in the battles on the Isonzo River, and on 15‐23.06.1918 in the Battle of the Piave River, near the town of San Donà di Piave. From there, on 30.10.1918, the regiment began to withdraw and on 17.11.1918 returned to Wadowice — 6 days after the armistice and ceasefire between the Allies and Germany signed on 11.11.1918 in the staff wagon in Compiègne, in the headquarters of Marshal Ferdinand Foch of France (which de facto meant the end of World War I) and the announcement of the Emperor of Austria–Hungary, Charles I of Habsburg, informing about his resignation from participation in the government.

After return, became a chaplain of the reborn Polish Army. During the Polish–Czechoslovak War, which began on 23.01.1919 with the Czech attack on Silesia and ended around 25.02.1919, was the chaplain of the field hospital in Bielsko. One of the units taking part in this war was the 12th Infantry Regiment formed mainly from soldiers of the former 56th Galician Infantry Regiment — a dozen or so of them were taken prisoner in Stonawa and then stabbed to death by the Czechs. Was still in Bielsko in 11.1919. At the beginning of 1920, during the Polish–Russian War of 1919‐1921, was the chaplain of the Command of the District Staging Region „Równe” (established on 14.08.1919, transformed into an independent Staging District on 13.03.1920), one of whose main tasks was to protect the railway lines behind the front. Prob. in 05.1920, when during the Kiev expedition the Russian offensive and the withdrawal of Polish troops began, transferred to the Command of the Staging Region „Chełm” in Chełm.

Perished there in the local field hospital when Russian troops were approaching Chełm, having contracted typhus (or dysentery).
