 When none of the prisoners complied with Zagórski's demand to pledge allegiance to the Central Powers, he ordered the soldiers to march shoe-less to an internment camp in Szczypiorno.Later, it was often recalled by the Polish Legions that as the column of shoe-less Poles marched past a furious Zagórski, the Polish soldiers bellowed out in unison the lyrics to "We Are the First Brigade", and added a fifth verse to the song where they verbally attacked Zagórski, ending the song with telling Zagórski to ""go f--- yourself"".As a result, Zagórski denounced several Polish Legion officers at the internment camp who entered undercover as regular soldiers with the aim of dividing the sentences among the imprisoned.
