On March 25, 1941, Dumitrescu was made commander of the Third Army, a post which he would hold for the duration of the war. On July 5, 1941, he attacked the Soviet forces in northern Bukovina and took Cernăuți (Chernivtsi), reclaiming territory occupied by Soviet troops since June 28, 1940. He then crossed the Prut to recover northern Bessarabia. The German Eleventh Army covered Dumitrescu's right flank while he advanced towards the Dniester. At that point his army and the German 11th army switched places, with Italians continuing advancement over the Dniester towards the Southern Bug river, and Dumitrescu remaining on recovered Romanian territory. In September of that year, Dumitrescu repulsed a Soviet attempt to cross the Dniester in the east, behind the Eleventh Army.
