[3] In February 1918, after the signing of Treaty of Brest, he was the initiator of the rebellion of 2nd Legion Brigade and its breakthrough through the front during the Battle of Rarańcza.

After the front had passed, he became the chief of staff of the Polish II Corps in Russia following his promotion to the rank of colonel.

After the corps was disarmed by the Germans after the Battle of Kaniów in May 1918, he served in command positions in the Polish Military Organization in Russia.

[1] One of his subordinates and later Prime Minister Felicjan Sławoj Składkowski, in his memoirs written in exile succinctly commented on his economic talents.

Following an official investigation, he was court-martialled and demoted to private first class, expelled from the army and sentenced to five years in prison.

Karol Popiel later claimed that accusing Żymierski of corruption was a kind of political revenge on the part of Józef Piłsudski and was supposed to indirectly discredit Władysław Sikorski.

He was recruited by Soviet intelligence and became a well-paid secret agent delivering information about the Franco-Polish alliance.

His secret engagement with Moscow was discontinued when Stalin ordered the dissolution of the Polish Communist Party (KPP) in 1938 during the Great Purge.

The civil court was probably unaware that Żymierski was then an agent of the NKVD, and the court's decision had no legal significance and force in the light of the applicable criminal law of the Second Polish Republic, as the only judicial authorities that could acquit Żymierski under the conditions of the occupation was the judicial system operating from May 1940.

[6] Under the pseudonym "Rola", he engaged in the Soviet dealings with Nazi German Gestapo secret police.

[1] On June 15, 1945, when the controversy over establishing the border with Czechoslovakia intensified, Żymierski, replacing the absent prime minister, issued an ultimatum to the Czechoslovak side.

[10] Żymierski received the title of 'Honorary Citizen' of cities Bielsko-Biała, Kraków, Włocławek, Płock, Chełm, Toruń, Kłodzko, Bydgoszcz, Łęczyca and Sosnowiec.
