"[10] The criticism coming from the "young" initially concerned tactical and psychological issues – the "old" were accused of "complete indolence, inability to act".

The mechanism of secession was set in motion only by the frustration caused by the lack of reaction of the movement's leadership to the dissolution of the Camp of Great Poland (OWP).

In the autumn of 1933, representatives of the "young" from Warsaw and Lwów met at Henryk Rossman's to work out a common position - mainly making personal accusations (incompetence, passivity), they decided to demand that Dmowski remove Tadeusz Bielecki and Aleksander Dębski.

The collapse of the organization came suddenly: the assassination of Bronisław Pieracki by Ukrainian nationalists on June 15, 1934, gave the Sanation authorities a pretext to deal with national radicals – after a wave of arrests, the camp was officially banned on July 10, 1934.

Ideological differences were already evident before the establishment of the ONR, at the beginning of 1934, then they intensified (extremists wanted armed struggle and radicalization of the social program), to explode with full force after B. Piasecki was released from the camp in Bereza Kartuska.

After World War II, the forced exile of many ONR members was made permanent by the newly created Polish People's Republic, which branded them enemies of the state.

Włodzimierz Sznarbachowski recalled that Bolesław Piasecki was greatly influenced by his acquaintance with Piłsudski's political thought during his stay in Bereza.

Over time, the positive opinion of the Legions began to transform into a postulate of a synthesis of “Polish political thought” (national-democratic) and “soldierly” (Piłsudski's).

"All the old divisions [...] are irrelevant and harmful" - proclaimed the Falangists, and "Sztafeta" echoed them: "It is time [...] to end the old [...] party disputes and outdated scores".

This sometimes led activists to conclusions that were downright shocking - Wojciech Zaleski is supposed to have said privately about Dmowski and Piłsudski: "it would be better for Poland if both old gentlemen died".

Jan Rembieliński wrote that “the ONR began in a completely fascist manner: young people in light shirts, raising hands in greeting.” According to Zygmunt Wojciechowski, the ONR program was “formulated […] with the undoubted influence of Hitlerist economic doctrines.” Jerzy Drobnik recalled that in May 1934 Mosdorf and Rossmann asked him to provide Nazi political literature.

Kajetan H. Stolarski wrote in the poem March of the Young: "we will raise our right hand, saluting the Sword of the Chrobry– our victorious sign!".

Its leadership included Henryk Rossman, Antoni Goerne, Mieczysław Harusewicz, Aleksander Heinrich, Jan Jodzewicz, Jan Korolec, Witold Kozłowski, Jerzy Kurcyusz, Wiktor Martini, Wincenty Mianowski, Witold Rościszewski, Tadeusz Salski, Włodzimierz Sylwestrowicz and Tadeusz Todtleben.

While the daily ABC was, from the fall of 1936, the main propaganda tube of the Rossmanists, the theoretical organ remained the "Nowy Ład" monthly.

However, the activities of the Rossmanists were also noted in Pomerania, Silesia, Podlasie (Lomza, Siedlce), Kraków, Wilno, Łódz, Czestochowa, Lowicz, Plock, Lublin, Łuck and Równe - these centers were represented at the ONR "ABC" congress in Lwów in late January 1937.

Another blow to the movement was the death of Henryk Rossmann in February 1937, followed by the departure of Wojciech Zaleski and Jerzy Kurcyusz in the course of the struggle for leadership.

Within the organization, there were ongoing discussions on tactics between supporters of the long-term "march through institutions" (i.e., infiltration of the state apparatus and major political forces) and enthusiasts of the "national revolution" (Wiktor Martini, Otmar Wawrzkowicz).

[20] In an attempt to resolve the impasse in 1937, the ONR "ABC" initiated the formation of the Polish Confederation - a movement with a vague program and a loose structure (the only body was to be the Citizens' Court).

The program of the Confederation, open to all national-Catholic elements, testified to the impoverishment of national-radical ideology - it was limited to vague slogans of "the good of the Polish Nation," "Christian ethics" and "social justice."

The project failed (in October 1938, the Confederation was dissolved by the authorities due to de facto abandonment of its activities), as did the attempt made the following year to legalize the National-Radical Party.

Representatives of the (editors of the magazines "Nowy Ład," "ABC," "Jutro") participated only in a loose agreement of young-national, national-Pilsudskiites and imperialist groups - the so-called Youth Press Committee.

Both the "venom of senile hatred" of the SN and the "chad of youthful megalomania" of the Falangists were subjected to symmetrical criticism; the National-State faction (ZMN) was equally negative.

Rossman was said to have already sought contact with the Sanation during his stay in Bereza; talks with representatives of the ruling camp began in the fall of 1936 and continued in the spring of 1937.

The [clarification needed] was the main initiator of Marshal Śmigły-Rydz's meeting with national youth at the "Arkonia" commerce on May 18, 1937, but did not achieve any success.

Still in the autumn of 1937, Tadeusz Gluziński handed Adam Koc a letter in which he wrote: "we declare that in the crackdown on the factors of the so-called folxfront, you can count on our full cooperation within the limits of our technical and propaganda capabilities, and regardless of the tactical attitude of other national groupings."

After OZN's break with the Falanga, the again revived the idea of compromise with sanation, as documented by a series of gestures, such as the conciliatory leaflet "In view of the Wilno events!"

In Poznań, the National Radical Electoral Committee put forward a candidate in only one district (Stanisław Kasznica), who received 457 votes; in Wielkopolska, ONR won 2 seats.

The dualistic structure - a strictly conspiratorial, hierarchical Polish Organization and overt activities (editorials of magazines, such as "ABC", participation in legal associations) - proved useful after the September defeat.

The most important was the decision made on October 14, 1939 to form the Military Organization Lizard Union, headed by Władysław Marcinkowski "Jaxa".

The most important formation of the NSZ-ONR was the Holy Cross Mountains Brigade established in August 1944 under the command of Captain Antoni Szacki, which was the only Polish military unit during World War II that openly collaborated with Nazi Germany.
