After the outbreak of World War I on 28.07.1914, Łódź, where ministered, very quickly found itself on the German–Russian front line. In the first months, it changed hands few times, depending on the situation on the front. The Russians withdrew from the city four times, leaving it without any authority (on 20‐21.08.1914, the Germans took advantage of this to occupy the city for a few days). The envoys of the Polish Legions, fighting under the banner of Austria–Hungary, used it to conduct a propaganda campaign. Were met with silence or even reluctance by the then pro‐Russian society. Similarly on 08.10.1914, when the Germans took power in the city for the second time. Then a unit of the Legions appeared on the streets of Łódź for the first time, the first Polish unit in its urban history, but it did not arouse any enthusiasm. Prob. at that time established contact with the Legions, performing pastoral ministry among its soldiers. Did this also later — the Germans left Łódź on 28.10.1914, to return there for a longer period on 06.12.1914, after the great, indecisive Battle of Łódź on 11.11‐06.12.1914, in which the losses of the Central Powers (Germany and Austria–Hungary) amounted to c. 160,000, including 36,000 killed, and the Russians 110,000‐280,000 — when the Legions tried to recruit to their units, with little success. Did this also after 03.05.1915, when the Russians were defeated in the Battle of Gorlice, which caused the front line to shift far to the east, to Belarus and Ukraine, and the escape of c. 3 million Russians — the occupying official apparatus, military, teachers, Orthodox clergy, etc., together with their families — into the depths of Russia. At that time, from 05.1915 to 24.11.1916, the southern part of the Łódź region was the main legionary centre in the area of the former Rus. Царство Польское (Eng. Polish Kingdom), part of the Russian Empire — because it was located on the territory of the Germ. Militärgeneralgouvernement Lublin (Eng. General Military Governorate of Lublin), controlled by Austria–Hungary. After the act of 05.11.1916, when the Central Powers promised the creation of the Germ. Königreich Polen (Eng. Polish Kingdom), under the rule of the Central Powers, from 25.11.1916 the Legions also began to operate openly in Łódź, on the territory occupied by Germany. At that time prob. continued to minister among their units.

Until 07.1917, when the so‐called oath crisis broke out, when almost the entire Legions — on the advice of their leader, Joseph Piłsudski — refused to swear an oath of allegiance to the ruler of Germany, Emperor William II. The rebellious soldiers of the Legions were interned, and Joseph Piłsudski was arrested. Prob. at that time began to cooperate with the clandestine Polish Military Organization POW, also founded by Piłsudski. Actedunder the nom‐de‐guerres „Vladiboy”, „Candle” and „Czaplain”. At the same time, conducted charity work, supporting those in need during the war, including being a member of the „Cheap Kitchen Committee”.

After the signing of the armistice and ceasefire on 11.11.1918 by the Allies and the Germans, in the staff wagon in Compiègne, at the headquarters of French Marshal Ferdinand Foch — which de facto meant the end of World War I; and also after the transfer on 11.11.1918 by the Regency Council — operating in the so‐called Germ. Königreich Polen (Eng. Polish Kingdom), i.e. on the territory occupied by the Central Powers (Germany and Austria–Hungary) — of the supreme authority over the army to Brigadier Joseph Piłsudski and his appointment as Commander‐in‐Chief of the Polish Army, which de facto meant the rebirth of the Polish state; joined the nascent Polish Army. Prob. became the chaplain of the 28th Infantry Regiment „Children of Łódź”, the formation of which had begun in Łódź as early as 12.11.1918. Already in 01.1918, its 2nd Battalion was sent to Volyn, to the Ukrainian–Polish front, while the 3rd Battalion went to Cieszyn Silesia, where it fought against the treacherously attacking Czechs (i.e. on 28‐30.01.1919 near Skoczów). On the other hand, the 1st Battalion, together with the command of the Regiment, left for the Polish–Ukrainian war front in 06.1919. There, in Eastern Lesser Poland, in Palahychi, c. 20 km east of Stanislaviv, it joined the 13th Polish Riflemen Regiment to create the 28th Kaniv Riflemen Regiment, of which became the chaplain.

The Regiment took part in the last battles of the Polish–Ukrainian war, and after the signing of the armistice in 09.1919 was transported to the Vilnius region, where served on the demarcation line between Poland and Lithuania (i.e. in Saldutiškis and Širvintos). Composed then the melody of the Regimental march.

On 14.05.1920, the first major Russian offensive began in the Polish–Russian War of 1919‐1921, a tactical response to the Polish Kiev expedition of 04‐05.1920. The Battle of the Berezina River began. The Regiment was transferred to the vicinity of the town of Hlybokaye and on 22.05.1920, took part in a bloody battle on the Hlybokaye–Boreiki section. From 28.05.1920, fought for the town of Kazyany, which it captured on 01.06.1920. From then on, Polish troops began to retake previously lost positions and on 05.06.1920, the Regiment occupied Sharkaŭshchyna, and after crossing the Berezina River, it reached the Auta River, a right tributary of the Dzisna River, on c. 16.06.1920.

On 04.07.1920, the great offensive of the Russian Western Front began. Despite tactical successes, the Regiment — together with the entire Polish army — was forced to withdraw from the Berezina River, to the west, never to return there. However, himself became famous there, as described in the application for the Cross of Valour: „06.06.1920, in the Battle of Pashki, during […] the action on Luzhki, […] with complete self–denial and dedication, fulfilled his pastoral duties under rifle and machine gun fire and helped to carry the wounded out of the lines […] Always devoted himself to helping soldiers, regardless of enemy fire, with true contempt for death, zealously, setting a beautiful example of fulfilling his duties”. From Auta River, the Regiment, in continuous retreat battles at Trokeli, Grodno, Indura, on the Narew River, near Białystok, Ostrów, arrived on 11.08.1920 in Jabłonna near Warsaw.

There took part in the decisive Battle of Warsaw of 15.08.1920 (known as the „Miracle on the Vistula”). Fought near the town of Radzymin, which changed hands several times. The turning point came on 15.08.1920, when Lieutenant Stephen Pogonowski, commanding one of the battalions of the Regiment, decided to start the attack before the main forces arrived. When was setting off to fight, got mortally wounded. The chaplain of the Regiment was also with the dying man, to whom Pogonowski told: „Valer, now help me establish contact with heaven, as you often told as to do. Let everyone go, please. Stay with me for a moment”.

Gen. Lucien Żeligowski, commanding the sector, commented: „At this point the page of the war turned, there was a psychological turning point for us and the Russians […] Pogonowski, guided by an extraordinary instinct, began the victory […] on the bridgehead Warsaw. This is the great significance of his deed and the glory of his soldierly death”.

Next the Regiment took part in the pursuit of the fleeing Russians. Fought, among others, at Sokil on 11‐13.09.1920 and in Volyn, where a ceasefire found it. Moved to the rearguard and then to the place of permanent deployment, to Łódź.

After returning, remained in the Polish Army as a chaplain.

His fate after retirement in 1932 is unclear. After a short pastoral ministry in the Pinsk diocese, did not, it seems, return to his native Warsaw archdiocese, or to Łódź, at that time the capital of the Łódź diocese.

And after the German and Russian invasion of Poland in 09.1939 and the beginning of World War II, after start of German occupation, was supposedly arrested by the Germans and imprisoned in KL Stutthof concentration camp.

And there was to perish.
