Following the
Nazi assumption of power, Weinert fled to Switzerland. From 1933 to 1935, Weinert, with his wife and daughter, Marianne Lange-Weinert, went into exile in the
Saar protectorate. From there, he went to
Paris,
France, and so he would be able to arrive in the
Soviet Union. Working in the Soviet Union, he published an anthology of anti-fascist poems in 1934, 'The Cobblestones and The Day Will Come'. He became a member of the
International Brigades in the
Spanish Civil War from 1937 to 1939, where he was active as a front correspondent and wrote battle poems. In July 1937 he attended the Second International Writers' Congress, the purpose of which was to discuss the attitude of intellectuals to the war, held in
Valencia,
Barcelona and
Madrid and attended by many writers including
André Malraux,
Ernest Hemingway,
Stephen Spender and
Pablo Neruda. He turned his experience on the Spanish front into poems, which were published in the book Camaradas (1951). using methods such as poems printed on handbills that were thrown off behind the German lines as well as making pleas to them via the radio and shouting slogans from the rubble of Stalingrad. In 1943 he was selected as the president of the
National Committee for a Free Germany. Once again the time spent on the front lines found literary expression. Weinert published his war diary under the title 'Remember Stalingrad' in 1943. Two short stories – 'Death for the Fatherland' and 'Expediency' – came out in 1942. A collection of leaflet poems written during the war came out in 1944 as 'Against the Real Enemy'. In 1947, he also published 'Chapter Two of World History: Poems About the Land of Socialism', an anthology of poems about the Soviet Union. ==Return to Germany==
