In November he took command of the 2nd Battalion from the 38th Regiment, and fought in December at the Battle of the Argeș, falling back towards Moldavia in a series of defensive actions.

In the summer of 1917 he fought at the Battle of Mărășești; for his service he was awarded the Order of the Crown, Grand Officer Class, and was promoted to major on 1 September 1917.

At the head of the Mountain Corps, he participated in Operation München, the Battle of the Sea of Azov, the Crimean campaign, and the Siege of Sevastopol.

[1] For his service during the Crimean campaign, Avramescu was promoted on 18 July 1942 to lieutenant general (general de corp de armată), and was awarded the Order of the Crown, Grand Officer Class (29 July 1942), the Order of Michael the Brave, 2nd Class (1 September 1942), and the German Cross, in Gold (25 October 1942).

In August 1944, on the eve of the Soviet Second Jassy–Kishinev Offensive, he took de facto command of the 4th Army, since general Ioan Mihail Racoviță was "away on leave" (preparing King Michael's Coup).

In the morning of 23 August, he and General Petre Dumitrescu were dismissed by Marshal Ion Antonescu and replaced by Ilie Șteflea.

[6] After Antonescu was arrested later that day during the Royal Coup, Avramescu was recalled to command the 4th Army on the side of the Soviets against the Germans and the Hungarians.

[9] According to the official report issued on 23 March 1945 by NKVD head Lavrentiy Beria, Avramescu was hit by a bullet through the car's windshield.
