This is the obverse of leaflet no. G2 which was dropped by the Royal Air Force on Düsseldorf and the Ruhr on, respectively, January 23/24 and 27/28, 1943. The headline translates to 'EXTERMINATION ZONE ON THE [river] BUG,' and the photograph purports to show a "smug German sentry standing by a row of corpses."*
The text begins:DIE AUSROTTUNGSZONE AM BUG
DER östliche Wall der „Festung Europa” wird an dem polnischen Fluss Bug instandgesetzt. Diesen Ostwall hat Hitler zur „Ausrottungszone” erklärt.
Seit drie Jahren setzen die Naziführer in Polen ihre Lehree von der „totalen Vernichtung fremden Volkstums” in die Tat um. Hunderttausende von Unschuldigen sind dieser Vernichtungspoltik zum Opfer gefallen und mit Maschinengewehren, Giftgas und Starkstrom beseitigt worden.
Translated:
EXTERMINATION ZONE ON THE BUGTHE Eastern bastion of the Fortress of Europe is being got ready along the line of the Polish river Bug. This East wall has been declared the area of extermination by Hitler.For three years now the Nazis leaders have in Poland been putting their maxim of "total destruction of foreign peoples" into practice. Hundreds of thousands of innocent peasants have been victims of this policy of extermination and have been killed off by machine-gunning, gassing and electrocution.
