Jörg Sackenheim (geb. 1917– ?) A Biography of Resistance

"The history of the Austrian Resistance Movement O5 in Tyrol and the role of architect and activist Jörg Sackenheim."

Jörg Sackenheim was born in 1917 in Bavaria and grew up in a Catholic family with strong Austrian roots. His formative years in the German Youth Movement (Scouts) until its ban in 1937 led to a fundamental rejection of National Socialism.
During his architecture studies in Munich and Vienna (1935-1938), he moved in explicitly anti-Nazi circles. He began active resistance work in the summer of 1938. In the spring of 1939, he was betrayed and arrested by the Gestapo in Heidelberg. After ten months in solitary confinement and 26 interrogations, a special court sentenced him to one year in prison.
Following his release in June 1940, he evaded surveillance using forged papers but was nonetheless conscripted into military service. As a soldier, he was severely wounded in May 1941 during the invasion of Crete (Operation Mercury). During his convalescence in Vienna in 1941/42, he resumed his resistance activities. An attempted desertion across the Hungarian border failed; he was arrested and sentenced to four months in prison, a punishment that was prevented through the intervention of helpers from Viennese and Innsbruck resistance circles (including Dr. Willi Stricker).
From the summer of 1942, he lived unregistered in Innsbruck and decisively expanded his resistance network. This included contacts with:
·       The Innsbruck group around Fritz Würthle and Dr. Hermann Flora.
·       Munich circles around Prof. Kurt Huber ("White Rose") and activists within the Wehrkreis (Military District) Command.
·       Resistance groups in Vienna and Linz.
After his official discharge from the Wehrmacht in 1944, he used his profession as an architect as cover for extensive travels to network resistance groups in Tyrol, Bavaria, Austria, Luxembourg, and Lorraine.
In the spring of 1945, he was tasked by Dr. Karl Gruber—the elected commander of the unified Tyrolean resistance movement—with organizing the Ötztal region. During the Tyrolean uprising in early May 1945, Sackenheim was a determined and armed key figure. On May 2, he was among the first to arrive at the "Palermo" command center, heavily armed with submachine guns and hand grenades, and actively participated in the successful liberation of Innsbruck.

Nazi Resistance in Tyrol and the Würthle/Flora Network

At the center of resistance activities in Innsbruck were the circle around Fritz Würthle (see blog post on Fritz Würthle) and the circle around Dr. Hermann Flora Sr. These groups built a far-reaching network with connections to various other resistance organizations both within Austria and abroad.
Key Connections of the Network:
·       The Munich "White Rose": Through the caricaturist Paul Flora, contact existed with the Munich student group around the Scholl siblings. Their leaflets were distributed in Innsbruck.
·       Socialist Groups in Vienna: Connections were maintained via the engineer and later State Councillor (Landesrat) Ortner.
·       Luxembourg Resistance: Through the Luxembourg native Armand Mergen, who was living in Innsbruck, contacts were made with resistance circles in his homeland.
·       Vienna Resistance: In 1943, contact was established with Dr. Karl Gruber, who was leading a Vienna-based resistance group from Berlin.
·       Allied Troops: A systematic connection was established via the French officer Ferdinand Zöllner, who had parachuted into Tyrol.
·       Partisans in the Mountains: The Würthle group made contact with armed Maquis groups in the mountains around Innsbruck (e.g., Gnadenwald, Ötztal), where deserters and escapees had gathered.
A significant event was the meeting on the Hungerburg in 1943, where, under the leadership of Fritz Würthle, the preparation of military actions was discussed concretely for the first time.
Despite the Gestapo's wave of arrests in 1943, which claimed Dr. Hermann Flora Sr., Father Steinmayr, and others, and despite the punitive transfer of Fritz Würthle to Lienz in 1944, the resistance activities could not be completely stopped. Weapons caches continued to be established, and networking efforts were advanced.
 

Jörg Sackenheim's Mission in the Ötztal Valley, March 1945

In March 1945, the architect Jörg Sackenheim—a close confidant of Dr. Karl Gruber—was dispatched as a liaison officer for the Innsbruck resistance movement O5 under the codename "Ing. Sarrer" to Sautens in the Ötztal valley.
In the Sautner hunting lodge, he met with the local resistance groups around Josef Raffl as their contact. His central objective was to bring the previously fragmented local groups under a unified command. He argued that only the O5 central command under Dr. Karl Gruber had connections to the Allies and could thus systematically procure weapons, radios, and false papers. The non-partisan goal was to protect Tyrol from combat operations, scorched-earth destruction by the retreating SS, and the escape of Nazi leaders.
After thorough scrutiny by Hans Haid and Wolfgang Pfaundler, his plans were accepted. A field above the Sautner church was designated as a drop zone for Allied weapons supplies. On the dangerous return journey to Innsbruck, Sackenheim had to carry his motorcycle over roadblocks set up by the resistance group.

The Immediate Danger: The Gestapo on the Move

Even in the second half of April 1945, shortly before the regime's collapse, the resistance group was acutely threatened. After Peter Falkner escaped from custody, Ida Parth succeeded in warning Mrs. Irma Saurwein in Huben just in time: the Gestapo was on its way to arrest the entire family. When Saurwein himself returned from a meeting with Dr. Karl Gruber, Fritz Würthle, Jörg Sackenheim, and Ing. Stigger at the Café München in Innsbruck, two Gestapo officers were already waiting for him in Umhausen. The planned arrest was only narrowly thwarted.
The bodies of these two officers were later recovered from the Ötztaler Ache river; they belonged to a special commando of the Berlin Gestapo that had fled from Verona.

The Role of the Conrad Barracks and Jörg Sackenheim in the Liberation of Innsbruck

A decisive center of military resistance in Innsbruck was the Conrad Barracks, specifically the Tank Hunter Replacement Company under First Lieutenant Anton Huber. Huber, supported by staff physicians Dr. Alois Kosch and Dr. Emil Eckl, consciously defied the regime's inhumane logic and kept his soldiers away from the front.
Through months of conspiratorial work by a senior lance corporal, the connection to the civilian resistance movement under Dr. Karl Gruber was established. First Lieutenant Huber immediately joined it. After consulting with the already opposition-minded Major Werner Heine, complete control over the barracks could be prepared. On 1 May 1945, Huber reported to Gruber that the barracks were completely in the hands of the resistance. The headquarters of the Austrian Resistance Movement (Ö.W.B.) was subsequently relocated to Huber's office.
On 2 May 1945, the decisive actions began. Under the military leadership of Major Heine and First Lieutenant Huber, and with civilian coordination by the long-time resistance fighter architect Jörg Sackenheim, the first major steps were taken. That very morning, units under Dr. Emil Eckl occupied the Klosterkaserne barracks and captured an SS staff. By late afternoon, all military and police offices in Innsbruck had fallen into the movement's hands.
The riskiest coup followed on the same day: a small troop of only 30 men under Heine, Huber, and Jörg Sackenheim drove to the headquarters of the fanatical Nazi combat commander General Böhaimb in Mariabrunn, surrounded it, and took the general and his staff prisoner. Two American officers were also freed in the process.
Despite this success, scattered SS and NSKK units at the Rum camp still offered fierce resistance, which was not broken until the next day. The subsequent skirmishes around the state parliament building (Landhaus) resulted in casualties and wounded on the resistance side.
On the evening of 3 May 1945, Dr. Karl Gruber was able to introduce himself to American Major Elliot as the provisional governor and report the bloodless surrender of the provincial capital and further parts of Tyrol. The brave rebellion of the soldiers in the Conrad Barracks and the close cooperation with civilian resistance forces like Jörg Sackenheim had thus decisively contributed to ending Nazi rule in Innsbruck.

🎯 Jörg Sackenheim's Role in the Resistance

Jörg Sackenheim was an architect and a core member of the close circles around both Dr. Hermann Flora Sr. and Fritz Würthle. He was among the most active proponents for forming armed units and helped drive the planning for militant actions. His work took place during a critical phase when the Tyrolean resistance was becoming more radicalized and interconnected.

📅 Key Activities and Development (1943-1945)

• Strategic Planning at the Hungerburg Meeting (1943): Sackenheim participated in the pivotal meeting on the Hungerburg near Innsbruck. Alongside figures like Fritz Würthle, Ing. Ortner, and Dr. Leo Praxmarer, they intensively discussed preparing for military action for the first time.
• Building an International Network: Using false papers, he successfully strengthened the connection to the Luxembourg resistance movement. He also established contact with higher-ranking military officers in Munich.
• Leadership in the Final Uprising (April 1945): In the decisive unification of Tyrolean resistance groups under Dr. Karl Gruber, Sackenheim was appointed head of the civilian combat groups.
• Ötztal Mission (March 1945): Acting as a courier for the Innsbruck O5 resistance movement under the alias "Ing. Sarrer," he was sent to Sautens in the Ötztal valley. His mission was to persuade the fragmented local groups there to unite under the central O5 leadership, arguing this was essential for securing Allied supplies and preventing a scorched-earth retreat by the SS.

🏛️ Post-War Life

After the war, Jörg Sackenheim lived in an artist's house in the exclusive Saggen district of Innsbruck, sharing the space with the cartoonist Paul Flora, artist Gerhild Diesner, and resistance comrade Bodo Kampmann.

💎 Conclusion

In summary, Jörg Sackenheim was not merely a sympathizer but a decisive and active operative. His efforts were focused on organizing a military arm for the resistance and expanding its international contacts, particularly to Luxembourg and Munich.

Report in the Tiroler Tageszeitung from 17.8.1945, Article about "The Military Stronghold of the Anti-Nazis" p. 2.

"The stronghold of the anti-Nazis was the Tank Hunter Replacement Company of the Mountain Infantry Replacement Regiment 137 in the Conrad Barracks.
At the head of the barracks stood First Lieutenant Anton Huber, who had long realized that the war was not only lost but beyond that completely senseless. First Lieutenant Huber did not want to send any of the soldiers entrusted to him to certain doom at the front. He did what he could, with the then staff physician Dr. Alois Kosch and Dr. Emil Eckl being particularly helpful to him. Soldiers who were kv. [kriegsverwendungsfähig - fit for combat] were written as a.v.[arbeitsverwendungsfähig - fit for work] and thus kept away from the front.
A Senior Lance Corporal of the Tank Hunter Replacement Company of Mountain Infantry Replacement Regiment 137 had secretly forged countless connections with resistance groups for months. He led his company commander, who had been prepared for a long time, to the camp of the then technical commander Dr. Gruber. Without hesitation, First Lieutenant Huber joined the resistance movement under Gruber's leadership. A brief discussion between the then battalion commander Major Heine and his adjutant Lieutenant Ludwig Steiner (1922–2015), both of whom had long been in the anti-Nazi camp, was enough to develop the preparation for the strategic plans and to make the existing forces ready for action. The soldiers in the Conrad Barracks had been largely instructed by their comrade, the Senior Lance Corporal, and thus First Lieutenant Huber was able to report to the technical commander Dr. Gruber on 1 May 1945 that the barracks were completely in the hands of the resistance.
Thereupon, the headquarters of the Austrian Resistance Movement (Ö.W.B.) was moved to the office of First Lieutenant Huber, which still meant a danger in those days, since the SS and Gestapo played a major role.
On 2 May 1945, the first major actions were launched under Major Werner Heine and First Lieutenant Huber, and for the civilian sector under the long-time resistance fighter, architect Mr. Jörg Sackenheim. Dr. Eckl had already occupied the Klosterkaserne at midday with a small handful of soldiers and some officers who showed particular bravery. Wire entanglements and barriers were placed in front of the barracks gates, and a staff of SS officers and men were taken prisoner. In the meantime, the Innkaserne and other army buildings were occupied, and by 5 p.m., all military and police offices were in the hands of the resistance movement.
Now the headquarters of the Combat Commander of Tyrol, which was under the supreme command of General Böhaimb, who was a fanatical Hitler mercenary, had to be raided. The decision was made, and under the leadership of Major Heine, First Lieutenant Huber and Jörg Sackenheim, a small troop of 30 men drove up to Mariabrunn, surrounded the headquarters, took the officers and the general prisoner, and locked the staff working there in the dining hall. Two American officers were freed from captivity during this action and brought to their troops, with Lieutenant Steiner accompanying the Americans on this dangerous journey.
That same night, the Rum camp near Innsbruck was then to be occupied. However, upon arrival, the resistance fighters were met with heavy fire. SS and NSKK had entrenched themselves there and were defending the camp. It was not until the next day at midday that Major Heine and the Senior Lance Corporal from the Conrad Barracks, who dared the bold enterprise, succeeded in getting the camp into the hands of the resistance. With weapons in hand, the two ordered the soldiers staying there to immediately board trucks and drive to the city to the Landhaus [State Parliament building]. Major Arthur Peter placed himself at the service of the resistance fighters and performed good service in the defense of the Landhaus against the SS. In the fights around the Landhaus, the resistance movement recorded one dead and several wounded. At 7 o'clock in the evening, Dr. Gruber was able to introduce himself to the American Major Elliot as provisional governor and hand over the capital of Tyrol and most of the country without a fight to the allied troops."
