After the abdication on 09.11.1918 of the German Emperor William II Hohenzollern; after the signing on 11.11.1918 by the Allies and the Germans, in the staff wagon in Compiègne, at the headquarters of French Marshal Ferdinand Foch, of the armistice and ceasefire — which de facto meant the end of World War I; and also after the handover on 11.11.1918 by the Regency Council – operating in the so‐called Germ. Königreich Polen (Eng. Polish Kingdom) occupied by the Central Powers (Germany and Austria–Hungary) — of supreme command 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, encompassing however only the Germ. Königreich Polen, i.e. the Polish territory under Russian rule until 1915, but excluding the lands of the Prussian partition; Greater Poland — as the Prussian Germ. Provinz Posen (Eng. Poznań Province) — was still formally part of the German state. And his Słupia parish was located in the Germ. Kreis Rawitsch (Eng. Rawicz county), located in the south of the Germ. Provinz Posen, bordering the Germ. Provinz Schlesien (Eng. Silesia Province). As early as 10.1918, in view of the visible signs of the German defeat, the Poles in Rawicz — in collaboration with the clandestine Inter‐Party Committee in Poznań, which recognized the Polish National Committee operating in Paris as the legal authorities of Poland, i.e. de facto committing treason against Germany — began to consider ways of taking over power in the district in the event of a German defeat. Rawicz was a garrison town, so on 13.11.1918 the Workers' and Soldiers' Council was established there, dominated by Germans, but soon on 18.11.1918 a competitive Polish County People's Council was also formed, the appeal of the Supreme People's Council, i.e. the revealed Inter–Party Committee in Poznań, which, however, had its seat in Miejska Górka, c. 8 km north of Rawicz.

When the Greater Poland Uprising broke out on 27.12.1918, the Poles did not decide to launch a direct attack on Rawicz — the German forces there were too strong. But after the Germans announced on 03.01.1920 the separation of the entire Germ. Kreis Rawitsch from Greater Poland and its annexation to the Germ. Provinz Schlesien, the Poles responded by occupying Miejska Górka. On 11.01.1919, the Polish–German talks that had been ongoing until then were broken off, and the Germ. Grenzschutz Ost (Eng. Eastern Border Guard) — a German paramilitary, terrorist, volunteer formation that militarily opposed the separation of the eastern territories from Germany — launched an attack, occupying the village of Sarnowa, located halfway between Rawicz and Miejska Górka.

Three days later, the Germans — a gang 250‐300 strong — attacked his Słupia Kościelna parish, c. 7 km east of Rawicz. They entered it, pushing out a small battalion of the insurgent army that was still forming at the time — in fact was its chaplain — which was part of the 1st Infantry Regiment that was also forming. The plundering of the village began — „they didn’t miss a single cottage, everywhere robbing geese, chickens, cows, grain, underwear, bedding, whatever they could”, recalled the witness. They also robbed the church and the rectory.

Perished then, shot prob. trying to get out of the town.

The Germans also killed 3 children.

Immediately afterwards, a Polish counterattack by a unit from Miejska Górka forced the Germans to withdraw from the village — „they escaped quickly, with rich loot”.

The Uprising ended on 16.02.1919 with the armistice in Trier, enforced by the victorious Entente states, under which the Polish insurgent Greater Poland Army was recognised as an allied army. However, it was not until the Treaty of Versailles, concluded on 28.06.1919, that Greater Poland — including the entire Rawicz county — formally joined Poland.
