Rudolf Alexander Karl Wilhelm Sieckenius (18 August 1896Bundesarchiv PERS 6/1829 Personalakte Sieckenius, Rudolf – 29 April 1945) was a German Generalmajor during World War II who commanded the 16 Panzer Division during Operation Avalanche (Salerno Landings) in September 1943. Despite his widely acknowledged success, which almost resulted in the Allies being pushed back into the sea, Sieckenius was made a scapegoat and sidelined until his death during the Battle of Berlin, when he commanded the 391st Wehrmacht security division.
Early life and World War I Rudolf Sieckenius was born in 1896 in Ludwigsthal, Silesia, as the second of nine siblings. His parents were Alexander Sieckenius, a businessman, and Luise Rittner, granddaughter of Saxon politician Carl August Rittner. Through maternal lineage, he was a cousin to General Heinrich von Prittwitz und Gaffron, whose grandmother, Maria Camilla Rittner, was Luise's aunt.
In 1908, possibly for religious reasons, the Sieckenius family moved from Katowice to Gnadenberg near Bunzlau. Due to investment errors, his father's business deteriorated and eventually declared bankruptcy in 1913. Despite the reported debts amounting to 340,000 Reichsmarks, Sieckenius and his brothers continued their costly Gymnasium education in Bunzlau until 1914, when the war interrupted the summer vacation. 18-year-old Sieckenius and his elder brother Otto-Heinrich joined up immediately on 22 August 1914 as Kriegsfreiwilliger, both enlisting in the Feldartillerie Regiment Nr.5, with which he served in the Russian front.
In November 1915, he was transferred as corporal to the 154th Infantry Regiment in France, serving successively as a platoon leader, company commander, and battalion adjutant. One of his comrades was Rudolf Carnap, who mentioned Sieckenius in his war diary:
Sikenius(sic) visits me and tells of the great enterprise of the previous night...he was there as leader of our assault troops....Sikenius speaks of a certain feeling that nothing could happen to him. (July 5, 1917)
After Germany's defeat, Sieckenius volunteered to join Freikorps Regiment Graf Yorck of the Upper Silesian Border Guard(Grenzschutz). He did not remain in the 100,000-man Heer but was discharged in October 1919 with the rank of Leutnant der Reserve.Bundesarchiv PERS 6/1829 Personalakte Sieckenius, Rudolf
Weimar Republic years
On 29 April 1920, as a Leutnant Sieckenius joined the police force where he served for fourteen years in Elberfeld and Wuppertal.Ibid. He initially served as adjutant to the Elberfeld police commander before being transferred to the driving unit, where his direct superior Hauptmann Christian Seelig became embroiled in a serious embezzlement scandal. For several years afterward, Sieckenius worked in administrative roles shuttling between the police headquarters of Elberfeld-Barmen-Remscheid and the Elberfeld district office, handling personnel matters.
In December 1923, his superior, Police Major Georg Hartmann, was charged with drunkenly singing "we don't need a Jewish republic" on the main street at midnight. It remains unclear how Sieckenius became entangled in this incident—local left-wing newspapers accused him of joining in the singing, though the police disciplinary files contain no reference to him.
In March 1925, during the mourning period for deceased Weimar President Ebert, Elberfeld was rocked by the infamous flag scandal when a national flag was cut down and destroyed at the Waldesruh police barracks. Sieckenius's friend, Police Oberleutnant Günther Schubert (later a Knight's Cross recipient), was considered the prime suspect. The subsequent criminal investigation was temporarily suspended due to Sieckenius's complaints against the detective, leading left-wing newspapers to repeatedly attack him as a "right-wing lieutenant" who was "extremely arrogant" and guilty of "obstructing the investigation."
Possibly in connection with this affair, Sieckenius was finally able to leave office position in summer 1925 to lead a police station (Revier Leiter). In 1929, as a police Hauptmann, he attended equestrian training in Potsdam. Upon his return, he successively commanded the mounted police units in Wuppertal and Remscheid, frequently participating in regional equestrian exhibitions and competitions.
Return to the Wehrmacht
Rudolf Sieckenius did not join any political party according to his 1933 questionnaire. With the Nazi rise to power, he appears to have remained unaffected, but in 1934 he made the decision to leave the police force and join the army in Breslau, transferring as a cavalry captain. On creation of the armored troops in late 1935, he transferred into the Panzer branch and was appointed a company commander in Panzer-Regiment 2 under his cousin Heirnrich von Prittwitz und Gaffron. After a further year as Major beim Regiments-Stab (major in the regimental headquarter), he was appointed to command the first battalion of the newly-formed Panzer-Regiment 15 at Sagan.
In November 1938 Sieckenius was promoted to commander of the 66th Panzer Battalion (Panzer-Abteilung 66) based in Eisenach.Bundesarchiv PERS 6/1829 Personalakte Sieckenius, Rudolf Serving as his adjutant was Hans Ulrich Schroeder, later a colonel in the Bundeswehr, whose diary records provide interesting insights into Sieckenius's character.
On late February 1939, following orders from his divisional commander, General Stumme of the 2nd Light Division, Sieckenius and his adjutant conducted a two-day reconnaissance mission to the Czech border, traveling in civilian clothes. A man who appreciated good wine, Sieckenius also took the opportunity to enjoy himself at Carlton Hotel in Marienbad.Bundesarchiv N 20/1 Hans Ulrich Schroeder diary, 1939
In March 1939, the division moved into Czechoslovakia as part of the German occupation. Sieckenius contracted a severe cold and sustained a high fever en route, which left him irritable and ill-tempered. Nevertheless, he refused to move to a hotel, sitting instead in a cold schoolroom and insisting he could not rest comfortably while his men still struggled through the snow.
Sieckenius and his officers were eventually billeted in Tloskau Castle, where they spent a period of friendship with the host family von Daněk-Esse. The bachelor, Sieckenius, was particularly charmed by the attractive lady of the house, Margarete, and paid her considerable gallant attention.Ibid.
The friendship between the Czech family and the German officers continued over the following years. In summer 1942, when the SS moved to requisition the castle, the Daněks appealed to Sieckenius for help. Despite being engaged in fierce combat on the Don River, he immediately intervened, reaching out to Kurt Daluege.
World War II
At the outset of the war, Sieckenius, now Oberstleutnant (Lieutenant colonel), led Panzer-Abteilung 66 in the Polish campaign. His leadership combined genuine courage with sometimes theatrical gestures. On September 4, 1939, during the advance on Szekocziny, Sieckenius risked his own life by climbing onto a tank stuck in mud, braving machine gun fire from a panicked crewman, in order to pull the crew out.Bundesarchiv N 20/1 Hans Ulrich Schroeder diary, 1939
On September 10 near Radom, after harshly rebuking an infantry battalion commander for failing to advance despite armored support, Sieckenius deliberately drove through enemy-occupied woods to shame the hesitant infantry into action. Spotting a riderless horse, he ordered it to be caught, declaring he would present it to the cautious infantry regimental commander 'to give him more mobility.' He then insisted on driving at walking pace while the horse was held alongside, despite ongoing enemy fire. His confident assessment that the woods were weakly held persuaded the divisional commander to order an advance. However, the troops met unexpectedly strong resistance, and Sieckenius later admitted his adjutant had saved his life by 'accidentally' breaking the horse's reins, allowing them to escape at speed.Ibid.
On September 15, Sieckenius was awarded the first Iron Cross of the division. However, a traffic accident en route made him arrive at division HQ bleeding profusely, and he had to receive medical treatment before his medal. Later that month, General Stumme praised him to General Hoth as "the finest commander in this division," noting his steel-like composure, bravery, and exceptional leadership that "far exceeds all expectations."NARA A3356 R797, Personal File Rudolf Sieckenius
In October, Sieckenius led his battalion back to Eisenach. Despite the successful Polish campaign, he expressed deep concern about the impending war, writing to his sister: "Thoughts of this new, likely even more severe war in the West occupy my mind almost day and night. At my age, one thinks differently about such things than 25 years ago. The thought of the hardships and many sacrifices it will again cost is at times utterly depressing."Rudolf Sieckenius file, Ronald MacArthur Hirst papers, Box 23, Hoover Institution
Under Erwin Rommel, Sieckenius remained in command of a Panzer battalion and took part in the Battle of France. His experience was vividly accounted in his own combat report. On 18 May 1940 at Cambrai, while under heavy enemy fire, Sieckenius left protection to jump from tank to tank, reassuring and directing his men until the gunfire wounded his left leg. As his men later recorded: "Our hearts were filled with both pain at leaving our commander and pride in him."Bundesarchiv N 20/2 Hans Ulrich Schroeder diary, 1940
In August 1940, a recovered Sieckenius returned to his battalion and enjoyed a period of respite in France. His battalion was said to have the best atmosphere of any unit. He granted his officers generous leave to visit Paris and even regularly hosted officer gatherings at Parisian bars. Whenever he entered, the bands would play Panzerlied - in recognition of this commander.Ibid.
In May 1941, to his great delight, Sieckenius was appointed commander of his former unit, Panzer-Regiment 2, now part of 16th Panzer Division under Generalmajor Hube.
Soon after, he took part in Operation Barbarossa, the invasion of the Soviet Union in June 1941. After Battle of Uman, on August 12, the 16th Panzer Division and the 1st SS Panzer Division advanced side by side towards the Black Sea port of Nikolayev. Despite being cut off from main forces, Kampfgrupp Sieckenius (combat group) engaged in an unprecedented three-day battle against the Soviet forces, eventually capturing Nikolayev on August 16, seizing the first Black Sea port for Germany. This victory earned him the Knight's Cross, making him the second member of the regiment to receive this honor, following Graf von Strachwitz.
Sieckenius's performance on the Eastern Front won recognition from multiple superiors, including General Kempf of XLVIII Corps and General Stumme, who directed his adjutant to contact the 16th Panzer Division about advancing Sieckenius's seniority, citing his "outstanding personal qualities and exceptional performance". His division commander, General Hube, was equally impressed, declaring Sieckenius "fully qualified for future panzer division command."NARA A3356 R797, Personal File Rudolf Sieckenius
On 17 December 1941 Sieckenius was promoted to Oberst, with seniority to date back from 1 February 1941.
Stalingrad pocket In mid-May 1942, the German offensive resumed. Operation Blue (Fall Blau) aimed to capture the oil fields of the Caucasus and secure the southern flank along the Don and Volga rivers. The 16th Panzer Division participated in the southern thrust toward Stalingrad.
