Going against the advice of Zhukov and other generals, Stalin emphasised attack over defence. In June 1941, he ordered a scorched earth policy of destroying infrastructure and food supplies before the Germans could seize them, also commanding the NKVD to kill around 100,000 political prisoners in areas the Wehrmacht approached. He purged the military command; several high-ranking figures were demoted or reassigned and others were arrested and executed. With Order No. 270, Stalin commanded soldiers risking capture to fight to the death describing the captured as traitors; among those taken as a prisoner of war by the Germans was Stalin's son Yakov, who died in their custody. Stalin issued Order No. 227 in July 1942, which directed that those retreating unauthorised would be placed in "penal battalions" used as cannon fodder on the front lines. Amid the fighting, both the German and Soviet armies disregarded the law of war set forth in the Geneva Conventions; the Soviets heavily publicised Nazi massacres of communists, Jews, and Romani. Stalin exploited Nazi anti-Semitism, and in April 1942 he sponsored the Jewish Anti-Fascist Committee (JAC) to garner Jewish and foreign support for the Soviet war effort.
