Avramescu served as General Officer Commanding of a number of army units: the 10th Division in 1941, the Mountain Corps in June 1941, the III Corps in October 1943, the VI Corps in February 1944 and 4th Army from 1944 to 1945. At the head of the Mountain Corps, he participated in Operation München, the Battle of the Sea of Azov, Crimean campaign and Siege of Sevastopol. After the fall of Sevastopol, his Corps occupied Crimea. For his service during the Crimean campaign, Avramescu was promoted on 18 July 1942 to lieutenant general, and was awarded the Order of the Crown, Grand Officer Class, the Order of Michael the Brave, 2nd Class, and the German Cross, in Gold. After the crushing defeat in the Battle of Stalingrad, in which he didn't participate, the Romanian Army was driven back to its own country during 1943 and the first half of 1944. In August 1944, on the eve of the Soviet Jassy–Kishinev Offensive, he took de facto command of the 4th Army, since generalIoan Mihail Racoviță was "away on leave". Avramescu could not prevent the disastrous defeat, because of the limited number of armored and motorized units at his disposal, and was dismissed on 23 August and replaced by Ilie Șteflea. After King Michael's Coup, he was recalled to command the 4th Army on the side of the Soviets against the Germans and Hungarians. He fought many battles with his 4th Army, including the Battle of Turda and the Battle of Debrecen. Avramescu complained repeatedly to the Soviets about the lack of supplies and impossible tasks for his Army. For this, he was relieved of command on 11 January 1945, and put on reserve. Nevertheless, he was promoted to general on 9 February and recalled to duty. Returning to the front, he successfully led the 4th Army in the assault on the Zvolen–Banská Bystrica line, in what was the prelude to the Bratislava–Brno Offensive in Slovakia.
Death
On 2 March 1945, when on the Slovakian front, General Avramescu was summoned by the commander of the Soviet 40th Army. After one hour, the Romanian delegation was told that Avramescu and the 40th Army commander, General Filipp Zhmachenko, left for the command post of the 2nd Ukrainian Front, as they were expected there by Marshal Rodion Malinovsky, leading later commentators to assert General Avramescu was arrested. The Romanian 4th Army was placed under command of General Nicolae Dăscălescu, who struggled to find out what had happened to Avrămescu. Zhmachenko advised him to find information about Avramescu at the Romanian Ministry of Defence or the Romanian General Staff. Avramescu was killed on March 3, 1945 in an aerial attack on the car which transported him, and his body was buried in Budapest's Soshalom cemetery. The general was the only occupant of the car to be killed. According to the official report issued on March 23, 1945 by NKVD head Lavrentiy Beria, Avramescu was hit by a bullet through the car's windshield. Also on 3 March 1945, Adela, Avramescu's wife and Felicia Avramescu-Sturdza, his daughter, were arrested and sent to Siberia. His daughter committed suicide; according to Soviet sources, this happened on 6 March 1945. Adela returned to Romania in 1956. On 23 October 2000, his remains were brought back to Romania and were reburied with military honours at the Hajongard cemetery of Cluj-Napoca. A bust of Avramescu has been erected in the city's "Ștefan cel Mare" Square.
