The Battle of Rostov (1941) was a battle of the Eastern Front of World War II, fought around Rostov-on-Don between the German Army Group South, commanded by General Gerd von Rundstedt and the Soviet Southern Front commanded by General Yakov Timofeyevich Cherevichenko.
It comprised three phases: the German Army Group South Sea of Azov Offensive Operation (begun on 12 September 1941), the Soviet Rostov Defensive Operation (5 November 1941 – 16 November 1941) by the Southern Front, and the Rostov Offensive Operation (27 November 1941 – 2 December 1941) executed by the same Soviet Front.
After concluding the Battle of Kiev in September 1941, the German Army Group South advanced from the Dniepr to the Sea of Azov coast. Walther von Reichenau's 6th Army captured Kharkov. Carl-Heinrich von Stülpnagel's 17th Army marched through Poltava towards Voroshilovgrad. Erich von Manstein's 11th Army moved into the Crimea and had taken control of all of the peninsula by autumn (except Sevastopol, which held out until 3 July 1942).
Ewald von Kleist's 1st Panzer Army advanced from Kiev, and encircled Soviet troops at Melitopol in October, then attacked east along the shore of the Sea of Azov toward Rostov at the mouth of the Don river, known as the gateway to the Caucasus.
Rostov was assigned as the objective for the 11th Army now commanded by General von Schobert, however he died in a crash on the same day after landing his liaison Fieseler Storch aircraft in a minefield. To replace him, General of Infantry von Manstein was ordered to travel from the Leningrad sector of the front to the extreme southern sector. He would also receive support from the 4th Luftwaffe Air Fleet.
At this time the LIVth Army Corps of the 11th Army was still engaged in Crimea, and because the Romanian forces were still engaged in the Siege of Odessa, the Army's resources for the Rostov objective were severely limited even against retreating Red Army troops. Therefore, initially von Manstein replaced the LIV Corps with the smaller XXXth Army Corps and XLIXth Mountain Corps, and ordered the LIV Corps into the first echelon in the advance to Rostov.
Late in September the 3rd Romanian Army joined the 11th Army in its advance towards Rostov, but was severely depleted by the attacks of the Soviet 9th and 18th Armies on 26 September. This forced a halt to the Army's advance to safeguard its flank, and forced von Manstein to use his only mobile reserve unit, the Leibstandarte Brigade to shore up Romanian defenses.
The Soviet counter-attack delivered as part of the general Donbass-Rostov Strategic Defensive Operation (29 September 1941 – 16 November 1941) also forced von Rundstedt (Army Group South) to order his 1st Panzer Army to manoeuvre in order to be better placed to counter any further Soviet thrusts in the Romanian sector of the front, and also to attempt an encirclement of the two Soviet Armies, which was partly successful in the area of Chernigovka where the commander of the 18th Soviet Army General-Lieutenant Smirnov was killed during the breakout attempt between 5 and 10 October 1941. This was interpreted by Hitler as such a success that he declared "The battle of the Sea of Azov is over." on 11 October before the troops had even reached their objective. As a commemorative gesture, Hitler issued the order to redesignate the Leibstandarte Brigade as 1st SS Division Leibstandarte SS Adolf Hitler.
The German 11th Army was ordered back to Crimea to effect the breakthrough of the Isthmus of Perekop.
Perceiving that the way to Rostov and the Caucasus was open, Hitler issued an order transferring the objective from the 11th Army to the 1st Panzer Army and attaching to it ill-prepared Romanian 3rd Army, the Italian Alpine Corps, and the Slovakian Motorised Brigade.
During the subsequent reorganisation of Axis forces the 3rd Panzer Corps and 14th Panzer Corps took the lead, supported by the XLIX Mountain Corps recently arrived from Crimea.
By 17 October 1941 the Mius river was crossed by the 14th Panzer Division and Taganrog was captured by German troops, with the mountain troops entering Stalino, forcing the newly formed 12th Army into a renewed withdrawal. However the Red Army was at this stage fortunate in that the Autumn rains had begun, and the infamous Rasputitsa had set in slowing the 1st Panzer Army's advance to "meter by meter". This meant that the leading German units did not reach the outskirts of Rostov until mid-November, having lost contact with the Red Army in the meantime.
The assault on Rostov began on 17 November, and on 21 November the Germans took Rostov. However, the German lines were over-extended, and von Kleist's warnings that his left flank was vulnerable and that his tanks were ineffective in the freezing weather were ignored.
On 27 November the Soviet 37th Army, commanded by Lieutenant-General Anton Ivanovich Lopatin, as part of the Rostov Strategic Offensive Operation (17 November 1941 – 2 December 1941), counter-attacked the 1st Panzer Army's spearhead from the north, forcing them to pull out of the city. Adolf Hitler countermanded the retreat. When von Rundstedt refused to obey, Hitler sacked him, and replaced him with von Reichenau. However, von Reichenau saw at once that von Rundstedt was right and succeeded in persuading Hitler, via Franz Halder, to authorise the withdrawal, and the 1st Panzer Army was forced back to the Mius River at Taganrog. It was the first significant German withdrawal of the war.
