In November 1915, Ksawery Zakrzewski died and Wincenty Wierzejewski took his place as leader. Henryk Śniegocki took command of the Scout Groups. Thanks to the aid of Józef Kostrzewski, Wierzejewski arranged a secret den in the Museum of PSFAS (Poznań Society of Friends of Arts and Sciences) and lived there. He also took a calculated risk himself, on the strength of a self-produced passport and travel document he tried to cross the border to Switzerland and contact the Polish Aid Committee.
