On 04.09.1944 / 23.09.1944 in Warsaw the Ukrainian Legion of Self–Defense ULS in the strength of the 2nd sotnya fought in Powiśle and Czerniaków in battles with insurgents and murdered civilians.
On September 4–23 in Warsaw, the Ukrainian Legion of Self–Defense took part in the battles with the insurgents and the murders of civilians. In the last days of August 1944, two times ULS (also called the Volhynia Legion, in the German nomenclature appearing as the 31st SD battalion — Sicherheitsdienst), numbering from 219 people (according to German sources) to 400 people (according to Polish and some Ukrainian sources), were regrouped from Bukowa Góra near Miechów to Warsaw. They entered the fight at least on September 4, suffering the greatest losses on that day (in general, most of the dead come from the period of September 4–9). This results from a letter from SS Oberscharführer Gustav Rauling of October 12, 1944, informing about the losses of ULS in Warsaw (vide: Marcin Majewski). Acting in Powiśle and Czerniaków against Group „Radosław” and Group „Kryska” and the landing units of the 9th Infantry Regiment of the 3rd Infantry Division from the 1st army of the Polish army lost from 25 to 30 dead. The commander was Colonel Petro Diaczenko, and his son, Major Jurko, took part in the fighting. From September 24, the legion was stationed in the forest of the Kampinos Forest, acting against Polish partisans and pacifying nearby villages, for example, on September 24, the village of Zaborówek (2 people were killed and 49 arrested, whose execution was prevented by. the Gestapo).
Between September 27 and October 1, ULS took part in Operation „Sternschnuppe” against the Home Army AK „Kampinos” grouping. In early October, Diaczenka's group returned to Miechów.
From August 1 to October 3, 1944 in Warsaw, during the uprising, various Ukrainian formations murdered from 3,075 to 16,350 Poles. „Kazimierz Podlaski (Bohdan Skaradziński) in his book «Belarussians, Lithuanians, The Ukrainians» (3rd edition, London 1985)  […] ends his pro–Ukrainian argument: «The Ukrainians constituted 1.5% of the garrison (German in Warsaw), so their role as pacifiers of the Uprising cannot be said seriously». 1.5% in the case of the Warsaw Uprising, this meant 270 killed and 75 seriously wounded insurgents, 3,000 murdered civilians and completely destroyed 156 buildings («Encyklopedia Warszawy», Warsaw 1994, p. 687)  […] and the Ukrainians were much, much larger percentage of soldiers in the German garrison in Warsaw, numbering on July 31, 1944 approx. 20,000 people (Władysław Bartoszewski «Days of the Fighting Capital. Chronicle of the Warsaw Uprising» London 1984), and then an average of 25,000 people. If there were only 7.5% of The Ukrainians among the soldiers of the German garrison in Warsaw, then these soldiers have on their conscience 1,350 killed and 375 badly wounded insurgents, 15,000 — murdered civilians and completely destroyed 780” buildings (vide: Marian Kałuski). Until now, Ukrainian nationalists and their supporters have denied the involvement of The Ukrainians in the slaughter of Warsaw during the uprising. „Blame Ukrainians, Kalmuków or «Vlasovtsi» murders on civilians have their sources in the Home Army AK propaganda of the” war period — say Hubert Kuberski and Jarosław Gdański in the article „Persistent legend: «Vlasovtsi» in the Warsaw Uprising”. From their thesis, it follows that the surviving witnesses succumbed to a collective hallucination, stunned by the „aK–like propaganda of the war period”, when they reported on the mass crimes of Kalmyks and The Ukrainians committed in front of their eyes during the Warsaw Uprising. Ukrainian historians (and some Polish) also claim that the witnesses confused the Russians (and even Kalmyks! — as azeris and Turkmen were called) with Ukrainians. Meanwhile, adult Varsovians (at least 40 years old) knew Russian well, Because when they were under Russian rule, they studied in this language at school and served in offices, so they could not confuse it with the Ukrainian language. This is first. The second fact is that in Warsaw there were a lot of refugees from the Eastern Borderlands, Volhynia and Podolia, who not only knew but could use the Ukrainian language, including specific varieties, by which it was possible to distinguish a Ukrainian from Volhynia from a Ukrainian from Eastern Lesser Poland. The Ukrainians taken prisoner were interrogated before being shot (apart from them, SS men were also shot), hence it was known where they came from, whether they came from Soviet Ukraine (from beyond Zbrucz), or were they Polish citizens of Ukrainian nationality from the Polish borderlands (officially from 1939 to 1945 years under the Soviet occupation). In the „Walka Śródmieście” newspaper of August 17, 1944, published during the Warsaw Uprising, on August 17, 1944, in the article „Hajdamaczyzna in Warsaw”, it was written: „though she screams outright to take care of her. It is about «the fruitful» collaboration of The Ukrainians with the Germans (as it is written in the original! – S. Ż.) In the fight of Poles for the right to their own national life, about the «Slavic brothers» hideous murders performed daily on defenseless Polish people, looting and arson — it is about a specific demeaning of a gloomy haidamaka with a rifle in his hand and a knife behind his boot. Involuntarily, the question arises for the ignorant: Where does this hate come from? What «rezun» from Stanisławów in Warsaw want?” It is a fact that, as an independent Ukrainian unit, the Legion of Ukrainian Nationalists took part in the suppression of the Warsaw Uprising. On the other hand, several thousand The Ukrainians (probably around 2,000–2,500) were in the RONa Brigade regiment, Oskar Dirlewanger's regiment, and police and Cossack units. For example, the 34th Police Rifle Regiment included one German battalion and two German–Ukrainian battalions. The English historian Martin Windrow in his work „The Waffen–SS” (London 1984) writes: „The Kaminski Brigade consisted of 6,500 renegades and murderers, mainly Ukrainians”. The total share of The Ukrainians in suppressing the uprising could be as much as 10% of the German forces. Both regiments were most ominously remembered by the population of Warsaw, RON in Ochota and Dirlewanger in Wola and the Old Town. Monstrous rapes of girls and women, mass executions of all civilians, looting, burning and demolishing houses and tenement houses in the captured area — this was their „combat trail”.
