The Battle for Vienna: When the Russians Crushed the Nazi Army

In mid-March 1945, the Joseph Stalin’s Soviet Red Army launched a major offensive with the aim of clearing Axis forces out of Hungary and forcing them back to the very borders of Hitler’s Greater German Reich. It was successful, and at 1925 hours on the 29th a “Führer Decision” finally arrived at the headquarters of Army Group South authorizing a phased withdrawal to what was called the Reichsschutzstellung—the Reich Guard Position.

This position followed the approximate line of Austria’s eastern border. Four days later, on April 2, Waffen SS General Sepp Dietrich, the commander of the Sixth Panzer Army, was presented to the people of Vienna as their “defender,” and over the next two days a number of his battered formations, notably the 2nd SS Panzer Division Das Reich, pulled back in chaotic conditions toward what had inevitably been designated Fortress Vienna. The withdrawal was complicated by roads jammed with miscellaneous German and Hungarian troops and hordes of civilians—all desperately trying to reach what they thought might be a place of safety.

Soviets Pushing Toward the Danube

By April 4, Das Reich, with a Kampfgruppe (battlegroup) from the 3rd SS Totenkopf Division on its left flank in the area of the Vienna airport, had been forced back to a line running roughly between the villages of Mödling and Achau. There it was tasked with preventing a Soviet advance along the main roads leading into Vienna from Wiener Neustadt and Sopron. But it was now clear that the Soviets were also beginning to push northwest toward the Danube River valley in the area of Tulln with the intention of outflanking and isolating the Austrian capital. Das Reich’s commander, SS Colonel Rudolf Lehmann, had little option other than to prepare to withdraw his Kampfgruppen into the city itself.

That same day, General Rudolf von Bünau was appointed commandant of the city of Vienna, and 24 hours later Lehmann received an order said to have come from the Führer himself, which ended: “From now on there is to be no more retreating.” By this time, however, his men, despite intense fighting, had been forced back some two and a half miles across flat, open ground to a low ridge running from Vösendorf to Leopoldsdorf. There they occupied temporary positions on a reverse slope.

Losses in Numbers, Rather Than Names
Some extraordinary events had occurred during the withdrawal toward and into Vienna. Some 2,800 men intended for the 12th SS Panzer Division Hitlerjugend but unable to reach that division had been quickly absorbed into Das Reich, and a reinforcement unit made up of convalescents, leave personnel, and replacement troops was quite literally taken off trains passing through Vienna and found itself in action under Lehmann’s command in the Piesting River sector.

In the same way, individual replacements arriving on April 3 had been quickly integrated, but according to SS Lt. Col. Otto Weidinger, the commander of the Division’s 4th SS Panzergrenadier Regiment Der Führer, it was no longer possible even to take down the names of these men. Losses were being recorded in numbers rather than names. He also recorded that just before the final withdrawal into the city most of Das Reich’s artillery was intact, but that the panzergrenadier regiments amounted to only “five average battalions” and the division had only 60 percent of its authorized motor transport.

Further Withdrawal to the High Ground

At 2000 hours on April 5, Lehmann gave orders for a further withdrawal to the high ground behind the Liesing River, running from Mauer through Altmannsdorf to the area of Inzersdorf. This new position was within the city limits of Vienna itself, and soon after occupying it the men, and particularly the officers of the division, began to run into new problems.

SS Captain Franz-Josef Dreike, the commander of the 2nd SS Flak Battalion, said later that for the first time in the war he experienced a local Germanic population that was unfriendly and even treated his men with contempt and scorn. He found himself getting into arguments with the commanders of the local Viennese defense sectors over responsibilities and rank. He also described how the personnel of a fixed 88mm Luftwaffe flak battery joined him and stayed with his battalion right to the end, displaying great bravery and apparently proud of the fact that they were suddenly part of the Waffen SS. Dreike was to receive a Knight’s Cross for his leadership at this time.

The Soviets Launch Their Major Assault

At 0730 hours on April 6, the Soviets launched a major assault on the German positions. It has been said that this attack was due to coincide with an attempt by the Austrian resistance movement to hand over the city to the Soviets. In any event, the attempt failed. The leaders of the movement had clearly not calculated on the presence of the men of the Waffen SS.

During the 6th, Das Reich’s 2nd SS Reconnaissance Battalion, under the command of Major Ernst Krag, pulled back through the division’s lines to the area around the Floridsdorf Bridge across the Danube. This vital bridge, which was to become the focus of the fighting in the last hours of the battle for Vienna, was already under observation from Soviet troops on the Kahlenberg feature in the northwestern part of the city.
