His published his most significant collection of war poetry, Tier rang gewaltig mit Tier (``Beast strove mightily with beast'') in 1920, in a limited edition of 1,000 copies. This short work of around 80 pages contains 60 poems based on the sonnet form, on themes of night and death. In his 1985 book in German war poetry, Patrick Bridgwater, Emeritus Professor of German at the University of Durham, described Schnack's book as ``the best single collection produced by a German war poet in 1914-1918'', and one work, ``N*chtliche Landschaft'', as the ``best poem of the war written in German''.
