The Jassy–Kishinev Operation,[1][9][10][11][Notes 1] named after the two major cities, Iaşi and Chişinău, in the staging area, was a Soviet offensive against Axis forces, which took place in Eastern Romania from 20–29 August 1944. The 2nd and 3rd Ukrainian Fronts of the Red Army engaged Army Group South Ukraine, which consisted of combined German and Romanian formations, in an operation to reclaim the Moldavian SSR and destroy the Axis forces in the region, opening a way into Romania and the Balkans.

The offensive resulted in the encirclement and destruction of defending German forces, allowing the Soviet Army to resume its strategic advance further into Eastern Europe. It also forced Romania to switch allegiance from the Axis powers to the Allies.

Setting the stage

The Red Army had made an unsuccessful attack in the same sector, known as the First Jassy–Kishinev Offensive from 8 April to 6 June 1944. In 1944, the Wehrmacht was pressed back along its entire front line in the East. By May 1944, the South Ukraine Army Group (Heeresgruppe Südukraine) was pushed back towards the prewar Romanian frontier, and managed to establish a line on the Dniester river, which was however breached in two places by Red Army bridgeheads. After June, calm returned to the sector, allowing the rebuilding of the German formations.

While up to June 1944, Heeresgruppe Südukraine was one of the most powerful German formations in terms of armor, it had been denuded during the summer, with most of its armored formations moved to the Northern and Central front, in order to stem Red Army advances in the Baltic states, Belarussia, Northern Ukraine, and Poland. On the eve of the offensive, the only armored formations left were the 1st Romanian Armored Division,[12] and German 13th Panzer and 10th Panzergrenadier Divisions.

Failure of intelligence

Soviet deception operations prior to the attack worked well. The German command staff believed that the movement of Soviet forces along the front line was a result of a troop transfer to the north. Exact positions of Soviet formations were also not known until the final hours before the operation.[13]

Soviet strategy

Stavka's plan for the operation was based on a double envelopment of German and Romanian armies by 2nd and 3rd Ukrainian Fronts.[1][14]

2nd Ukrainian Front was to break through north of Iaşi, and then commit mobile formations to seize the Prut River crossings before the withdrawing German formations of 6th Army could make it there. It was then to introduce 6th Tank Army into the battlefield to seize the Siret River crossings and the Focşani Gap, a fortified line between the Siret River and the Danube.

3rd Ukrainian Front was to attack out of its bridgehead across the Dniester near Tiraspol, and then insert mobile formations with a mission to head north and meet the mobile formations of 2nd Ukrainian Front. This would lead to the encirclement of the German forces near Chişinău.

Following the successful encirclement, 6th Tank Army and 4th Guards Mechanized Corps were to be launched towards Bucharest and the Ploieşti oil fields.

Both the 2nd and the 3rd Ukrainian Front undertook a major effort, leading to a double envelopment of the German Sixth Army (2nd formation) and parts of the Eighth Army. The German–Romanian front line collapsed within two days of the start of the offensive, and 6th Guards Mechanized Corps was inserted as the main mobile group of the offensive. The initial break-in in the 6th Army's sector was 40 km (25 mi) deep, and destroyed rear-area supply installations by the evening of 21 August. By 23 August, the 13th Panzer Division had dissolved as a coherent fighting force, and the German 6th Army had been encircled to a depth of 100 km (62 mi). The Red Army mobile group managed to cut off the retreat of the German formations into Hungary. Isolated pockets of German formations were trying to fight their way through, but only small remnants managed to escape the encirclement.

Operations of 3rd Ukrainian Front (Commander Army General Fyodor Tolbukhin)

The main effort of the front was in the sector of the 37th Army (2nd formation) (Commanded by Lieutenant General Sharokhin). The main effort of the 37th Army was with 66th Rifle Corps and 6th Guards Rifle Corps. The 37th Army had a 4 km (2.5 mi)-wide breakthrough frontage assigned to it. It was divided in two groupings, two Corps in the first echelon, and one Corps reserve. According to the plan, it was to break through the depth of the German–Romanian defense lines in seven days, to a distance of 110–120 km (68–75 mi), with a goal to cover 15 km (9.3 mi) per day during the first four days.

66th Rifle Corps (Commanded by Major General Kupriyanov), consisted of two groupings (61st Guards Rifle and 333rd Rifle Divisions in the first echelon, and 244th Rifle Division in reserve). Attached were 46th Gun Artillery Brigade, 152nd Howitzer Artillery Regiment, 184th and 1245th Tank Destroyer Regiment, 10th Mortar Regiment, 26th Light Artillery Brigade, 87th Recoilless Mortar Regiment, 92nd and 52nd Tank Regiment, 398th Assault Gun Regiment, two Pioneer Assault Battalions, and two Light Flamethrower Companies.

Corps frontage 4 km (2.5 mi)
Corps breakthrough frontage 3.5 km (2.2 mi) (61st Rifle Division 1.5 km (0.93 mi), 333rd Rifle Division 2 km (1.2 mi))

Troop density per kilometer of frontage:

  • Rifle battalions 7.7
  • Guns/mortars 248
  • Tanks and assault guns 18


  • Infantry 1:3
  • Artillery 1:7
  • Tanks and assault guns 1:11.2

There is no manpower information on the divisions, but they probably had between 7,000–7,500 men each, with 61st Guards Rifle Division perhaps at 8,000–9,000. The soldiers were prepared over the course of August by exercising in areas similar to those they had to attack, with emphasis on special tactics needed to overcome the enemy in their sector.

Troops density in 61st Guards Rifle Division sector per kilometer of frontage was:

  • Rifle battalions 6.0
  • Guns/mortars 234
  • Tanks and assault guns 18

Troops density in 333rd Rifle Division sector per kilometer of frontage was:

  • Rifle battalions 4.5
  • Guns/mortars 231
  • Tanks and assault guns 18

Initial attack

The 333rd Rifle Division did not establish a reserve and put three regiments in the first echelon. The 61st Guards Rifle Division attacked in a standard formation of two regiment in the first echelon and one in reserve. This proved to be fortunate, because the right wing of the 188th Guards Rifle Regiment was unable to advance past the Plopschtubej strongpoint.[Clarification needed] The 189th Guards Rifle Regiment on the left wing made good progress though, as did 333rd Rifle Division on its left. The commander of 61st Guards Rifle Division therefore inserted his reserve (the 187th Guards Rifle Regiment) behind the 189th Guards Rifle Regiment to exploit the break-in. When darkness came, the 244th Rifle Division was inserted to break through the second line of defense. It lost its way though, and only arrived at 23:00, by which time elements of 13th Panzer Division were counterattacking.

The German–Romanian opposition was XXX. and XXIX. AK, with the 15th and 306th German Infantry Divisions, the 4th Romanian Mountain Division, and the 21st Romanian Infantry Division. The 13th Panzer Division was in reserve. At the end of day one, the 4th Romanian Mountain (General de divizie, (Major General) Gheorghe Manoiliu), and 21st Romanian Divisions were almost completely destroyed, while German 15th and 306th Infantry Divisions were heavily damaged (according to a German source: the 306th Infantry lost 50% in the barrage, and was destroyed apart from local strongpoints by evening). Almost no artillery survived the fire preparation.

The 13th Panzer Division counter-attacked the 66th Rifle Corps on the first day, and tried to stop its progress the next day, but to no avail. A study on the division's history says 'The Russians dictated the course of events.' The 13th Panzer Division at the time was a materially understrength, but high manpower unit, with a high proportion of recent reinforcements. It only had Panzer IVs, StuG IIIs and self-propelled anti-tank guns. By the end of the second day the division was incapable of attack or meaningful resistance.

At the end of the second day, the 3rd Ukrainian Front stood deep in the rear of the German 6th Army. No more organised re-supply of forces would be forthcoming, and the 6th Army was doomed to be encircled and destroyed again. Franz-Josef Strauss, who was to become an important German politician after the war, served with the Panzer Regiment of the 13th Panzer Division. He comments that the division had ceased to exist as a tactical unit on the third day of the Soviet Offensive: 'The enemy was everywhere.'

The comment on the result of 66th Rifle Corps operations in Mazulenko is that "Because of the reinforcement of the Corps and the deep battle arrangements of troops and units the enemy defenses were broken through at high speed."

Comments by German survivors on the initial attack were that "By the end of the barrage, Russian tanks were deep into our position." (Hoffmann). A German battalion commander (Hauptmann Hans Diebisch, Commander II./IR579, 306.ID) commented that "The fire assets of the German defense were literally destroyed by the Soviet fighter bombers attacking the main line of resistance and the rear positions. When the Russian infantry suddenly appeared inside the positions of the battalion and it tried to retreat, the Russian air force made this impossible. The battalion was dispersed and partly destroyed by air attacks and mortar and machine gun fire."

Alleged Romanian collapse

It is often alleged that the speed and totality of the German collapse were caused by Romanian betrayal. For example, Heinz Guderian wrote of Romanian betrayal in his book "Panzer Leader". The study of the combat operations by Mazulenko indicates that this is probably not correct. Romanian formations did resist the Soviet attack in many cases, but were ill-equipped to defend themselves effectively against a modern army, due to a lack of modern anti-tank, artillery, and anti-air weapons. In contrast to German claims, for instance, in the symposium notes published by David Glantz, or in the history of the Offensive published by Kissel, it appears that Romanian 1st Armoured Division did offer resistance against the Soviet breakthrough.[15] However, Mark Axworthy states in his book Third Axis, Fourth Ally that the battered 1st Armoured Division maintained cohesion, experiencing some local, costly successes before being forced to cross the River Moldova.[16] Axworthy claims that the postwar Communist government would have obviously used this act of betrayal for propaganda purposes. Also, there are no Soviet reports of a collaboration before 24 August 1944.[17] The Soviet rates of progress imply a rather ineffective defense of the Romanian troops than active collaboration and en-masse surrender.[18]

Dumitru I.S [19] was a Romanian tank commander in the battle of Romanian 1st Armoured Division against Soviet tanks and he described the battle in his book "Tancuri în flăcări. Amintiri din cel de-al doilea război mondial." (Tanks in flames. Memories of the Second World War). Bucharest, Nemira 1999. According to Dumitru I.S, battle took place near Scobalteni village in vicinity of a town called Podu Iloaie, on August 20. Romanian division destroyed 60 Soviet tanks and lost 30 tanks. At the end of the day, Romanians decided to retrait to south after an analysis of the military results of the day.

The complete collapse of the German 6th Army and the Romanian 4th Army was more likely caused by the inability of the numerous horse-drawn infantry divisions to maintain cohesion while on retreat and under attack of the Soviet mechanized troops.[20] This claim is reinforced by the fact that the only Romanian division which retained its cohesion under the Soviet attack was the 1st Armoured Division, which had the mobility and the anti-tank weapons needed to do so.

The surrender of Romania took place at a time when the Soviet Army already stood deep inside Romania, and the German 6th Army had been cut off from the rest of the Wehrmacht troops in Romania. The opening of hostilities between the Wehrmacht and the Romanian Army commenced after a failed coup d'état by the German ambassador.

German–Romanian combat

Military operations, 23 – 31 August 1944.

Concurrently, a coup d'état led by King Michael of Romania on 23 August deposed the Romanian leader Ion Antonescu. German military formations promptly attempted to seize Bucharest in order to suppress the coup the following day, but were repelled by Romanian troops, who had some air support from the USAAF. German forces moving in to reinforce the assault on Bucharest from the west bank of the Prut were cut off and destroyed by the rapidly advancing Soviet Army. At the same time, Wehrmacht formations guarding the Ploieşti oil fields were attacked by Romanian troops, and attempted to withdraw to Hungary, again suffering heavy losses in the process. During the fighting, the Romanian Army captured 50,000 German prisoners, who were later surrendered to the Soviet Army.[21]

Romanian sources claim that internal factors played a decisive role in Romania's liberation from the Nazis, while external factors only gave support; this version is markedly different from the Soviet position on the events, which holds that the Offensive resulted in the Romanian coup and liberated Romania with the help of local insurgents.[14][22]


Romanian and Soviet soldiers shaking hands in Bucharest after the coup, 30 August

The German formations suffered very high irrecoverable losses of over 200,000 men with 115,000 POWs, out of which 55,000 died before being transported to the Soviet Union[citation needed]. Remarkably, Soviet losses were extremely low for an operation of this size. The Red Army advanced into Yugoslavia and forced the rapid withdrawal of the German Army Groups E and F in Greece, Albania and Yugoslavia to rescue them from being cut off. Together with Yugoslav partisans and Bulgaria they liberated the capital city of Belgrade in 20 October.

On the political level, the Soviet offensive triggered King Michael's coup d'état in Romania, and the switch of Romania from the Axis to the Allies. Almost immediately, a small border war between Romania and Germany's forced ally Hungary erupted over territory that Romania was forced to cede to Hungary in 1940, as a result of the Second Vienna Award.[23]

Following the success of the operation, Soviet control over Bessarabia and Northern Bukovina, which had been occupied by the USSR in 1940, was re-established. Soviet forces proceeded to collect and expel the remaining Romanian troops. According to Anatol Petrencu, President of the Historians' Association of Moldova, over 170,000 Romanian soldiers were deported, 40,000 of which were incarcerated in a prisoner-of-war camp at Bălţi, where they died of hunger, cold, disease, or were executed.[24]
