first line of defense. That evening, the Romanian division reached the second line of defense. The 1st Cavalry Brigade took Severinovca and joined the 1st Armored Division. At the same time, the 10th Dorobanți Regiment overran the Soviet forces at Lozovaya. The 4th Army gradually closed the circle around Odessa, but the offensive was temporarily stopped by Ion Antonescu on 13 August to strengthen the line west of the Hadjibey bank. The offensive resumed on 16 August, as Romanian troops attacked along the entire line, capturing Odessa's water reservoirs on 17 August. The Soviet forces put up a stubborn resistance, launching repeated counter-attacks, inflicting and taking heavy casualties. The Royal Romanian Air Force actively supported the ground troops, disrupting Soviet naval traffic to and from Odessa, and also destroying an armored train on 20 August. By 24 August, despite constant attacks, the Romanians were bogged down in front of the Soviets' main line of defense. The 4th Army had already suffered 27,307 casualties, including 5,329 killed in action. Nevertheless, the Soviets were also weakened, and thanks to the capture of Kubanka, Romanian heavy artillery now threatened the port of Odessa. Over the next three days, there was a lull in the fighting. On 28 August, the Romanians resumed their offensive, reinforced by a German assault battalion and ten heavy artillery battalions. The 4th, 11th and 1st Army Corps advanced towards Gnileakovo and Vakarzhany, only to be pushed back in some areas by a strong Soviet counterattack the following day. On 30 August the Romanians retook the initiative, but gained very little ground. Hitler and the German High Command noted that 'Antonescu [was] using at Odessa the tactics of the First World War,' depending upon infantry to make unsupported frontal attacks against Soviet trench line defenses. The Soviets temporarily retook Kubanka but were driven back by nightfall. Soviet troops in Vakarzhany were encircled and continued to fight until 3 September, when combined German and Romanian infantry successfully stormed the village. On 3 September, General Ciupercă submitted a memoir to by-now Marshal Antonescu, highlighting the poor condition of the front-line divisions, which were exhausted after nearly a month of continuous fighting. He proposed a reorganization of six divisions (the 3rd, 6th, 7th, 14th, 21st Infantry and Guard Divisions), which would be split into 2 corps and supported by 8 heavy artillery battalions. These units would then attack in a single area to
