Situation in the Legions during the oath crisis. 1917.

NATIONAL WORKERS' UNION. Polish soldiers! We address you as those whose hearts, since the beginning of the war, have beaten with one pulse with your hearts [...]. We turn to you at a time when the continued existence of the Legions, which are [...] the only refuge for our future, has been threatened [...] by the insane agitation from within going [...]. As three years ago in Mszana dolna, so today any action that breaks up the Polish Army [...] is madness or a crime [...]. Long live the Polish Army! Long live a free and independent People's Poland! Warsaw, August 22, 1917 [Subp.] Board of Directors of the National Union of Workers.
