Otto Dix, Sturmtruppe geht unter Gas vor (Assault under Gas) 1924 - Deutsches Historisches Museum, Berlin
This work is part of Dix's War series, which he painted after the war itself. When this was exhibited in Germany, it was felt that Dix had little regard for his fellow veterans, since most of the series dwelt on German troops, and dwelt on them negatively, rather than allied soldiers. Little wonder that, when the Nazis came to power, they blacklisted Dix's art as degenerate, had him sacked from the Dresden Academy, burnt some of his works and, when they allowed him to paint again, ordered him to do landscapes only.
Onto the work itself.
Nightmarish, inhuman, depraved, savage, horrific. Indeed, what more needs be said?
Absolutely stunning.
