Starting the Second World War since the invasion of Poland, Germany had only about a hundred Panzer III tanks, so in the Polish campaign and the battles with the French and British armies in the west, this tank was not so noticeable among the mass of more outdated tanks with which at that time it was armed tank forces Germany. But by the beginning of the eastern campaign of the Wehrmacht, the Pz.III had already become the main tank of the German army. On the Soviet borders on June 22, 1941, there were 965 Panzer III tanks.

Bio of Generalmajor Rudolf Sieckenius (1896-1945)

Rudolf Sieckenius was born in Ludwigstal, Silesia, on May 16, 1896, the son of Alexander Sieckenius, a successful businessman. Both men planned for Rudolf to follow in his father’s footsteps. In school, he studied accounting and industrial mathematics, as well as French, because the family business required trips to the south of France and Lorraine.

The outbreak of World War I in August 1914 totally disrupted the family’s plans. Rudolf was no less affected by the patriotic fervor that swept Germany than the typical 18 year old, and he joined the 5th Foot Artillery Regiment of the Silesian 9th Infantry Division on the 22nd of that month. He fought on the Western Front as part of the Crown Prince’s 5th Army, taking part in the invasion of Lorraine. In September, the division (along with the 10th Infantry Division from Posen) established itself in the Côtes de Meuse (the Calonne trench), where it remained for two years. Sieckenius, meanwhile, transferred to the cavalry and applied for officers’ training. More infantry officers were needed than cavalry officers, however, so Sieckenius again changed branches. He underwent a brief training course and, on December 27, 1916, graduated as a ‘‘90-day wonder,’’ as the enlisted men somewhat derisively called the new second lieutenants (but never to their faces). Commissioned in the 154th Infantry Regiment (also of the 9th Infantry Division), Sieckenius served as platoon leader in the trenches and became a battalion adjutant in November 1917. He fought in the Côtes de Meuse again (from February through the end of April 1917), in the California Plateau sector (May to September 1917), and at Chemis des Dames (September to December 1917). Sieckenius’s unit was pulled out of the line at the end of 1917 and partially rebuilt. It did not return to combat until March 1918, when it suffered heavy losses at the Battle of Picardy. Withdrawn again, it fought in the Battle of Aisne, where it lost another 3,000 men.

Sieckenius and his comrades fought in the Second Battle of the Marne in the summer of 1918 and in the Champagne district that fall. A first-class division from 1914 through 1917, its performance deteriorated in 1918 and, on November 4 alone, 1,800 of its men were captured. Rudolf Sieckenius was not among them, however; he was still fighting at the end of the war. Following the collapse of the Second Reich in November 1918, he was discharged from the army on October 20, 1919.

When Sieckenius returned to Silesia in 1919, the new Germany—which was called the Weimar Republic—was characterized by civil unrest, rebellion, political confusion, occasional anarchy, and economic turmoil. Like many former officers, Rudolf decided to join the police. He applied for a post with the Silesian Landespolizie (State or Provincial Police) and entered the service on April 29, 1920. Two months later, he was a police lieutenant.

Rudolf Sieckenius did well in the Weimar civil service. He became a qualified instructor in calisthenics and physical fitness (and retained his thin waist throughout his life), attended the excellent Equestrian Training School at Bamberg, and was named commander of the elite Escort Company of the Silesian Mounted Guards Police Battalion. He was promoted to first lieutenant in 1923 and to captain of police in 1928.

Hitler came to power in 1933 with the avowed intention of expanding the army, a program he secretly began in 1934. When Sieckenius read a memorandum from the Reich’s Defense Ministry soliciting former soldiers in the civil police to resume their military careers, he jumped at the chance. On May 27, 1934, he was gazetted Rittmeister (captain of cavalry) in the I Squadron of the 11th Cavalry Regiment, which was based in Breslau. Initially, he was OIC (officer-in-charge) of the regimental stables. On April 1, 1935, however, he was transferred to Stuttgart as chief staff officer of the 7th Heavy Cavalry Regiment. Shortly thereafter, he was placed in charge of the motorized elements of the regiment—the 1st, 2nd, and 3rd Motor (Truck) Detachments. He was thus in a position to become familiar with motorized warfare.

In October 1935, General of Mobile Troops Oswald Lutz and Colonel Heinz Guderian created the first three panzer divisions. Sieckenius quickly transferred to the new panzer branch and was named commander of the 6th Panzer Company, 2nd Panzer Regiment, which was part of the 1st Panzer Division at Weimar. He was promoted to major on March 1, 1936.

Despite his rank, Sieckenius continued to command his company until October 6, 1936, when he was appointed Ordnance (Orderly) Officer to Lieutenant General Baron Maximilian von Weichs, the divisional commander. In October of the following year, Weichs was promoted to the command of Wehrkreis XIII at Nuremberg, and Sieckenius was transferred to the command of the I Battalion of the newly formed 15th Panzer Regiment at Oppeln. Here he found that he could not get along with Lieutenant Colonel Johannes Streich, the mediocre commander of the 15th Regiment, who was a difficult superior. Their relationship deteriorated to the point that, in January 1939, Striech shouted at both of his battalion commanders (Sieckenius and Paul Goerbig) in public—and they shouted back! The division commander remedied this impossible situation by arranging for both Sieckenius and Goerbig to receive lateral transfers. Goerbig was given command of the 67th Panzer Battalion of the 3rd Light Division, while Sieckenius received command of the 66th Panzer Battalion of the 2nd Light.

Sieckenius’s new division was commanded by Georg Stumme, a competent but pleasure-loving general. The atmosphere, Friedrich von Stauffenberg wrote later, was ‘‘very congenial’’ and the 2nd was ‘‘a crack, well-officered division.’’ Sieckenius soon developed a close personal friendship with Major Walter von Neumann-Silkow, the commander of the 37th Reconnaissance Battalion.

The 2nd Light went into battle in southern Poland in September 1939 and acquitted itself well. Every officer in a position to know, however, recognized that the light divisions had proved to be unbalanced and difficult to command in Poland. No one was sorry when OKH announced in mid-October that they were to be converted into panzer divisions. The 2nd Light became the 7th Panzer, and Sieckenius’s battalion became the III Battalion of Rothenburg’s 25th Panzer Regiment. Sieckenius, meanwhile, was promoted to lieutenant colonel on October 1, 1939.

Sieckenius did well in France and, at one point in the pursuit, his battalion was the only one that could keep up with the hard-charging Rommel. The III remained in the Bordeaux region of France until February 1941, when Rommel was transferred to North Africa and was replaced by the more congenial Major General Baron Hans von Funck, who would command the 7th Panzer Division for the next three years.

Funck’s first task was to move his division back to its home base of Gera in Germany. The 25th Panzer Regiment was then supplied with a shipment of new tanks. Sieckenius and his men were busy running them in; meanwhile, Hitler decided to double the number of his panzer divisions by cutting the tank strength of each in half. Experienced panzer officers were in great demand and, on April 30, Rudolf Sieckenius said farewell to his officers, men, and friends, and traveled to Bucharest.

There, he joined the newly formed 16th Panzer Division, which was in the process of loading aboard trains for a move back to Niesse, Silesia.

When he arrived in Bucharest, Sieckenius found that he was there to replace Colonel Hero Breusing, the commander of his own old regiment, the 2nd Panzer. The circumstances were not the best. Although every major panzer leader except Walter Nehring thought Hitler’s plans to create 20 panzer divisions from the original 10 was a bad idea, only Hero Breusing said so publicly. A highly respected expert in mobile warfare, Breusing had served in the Motor Transport Branch under both Lutz and Guderian since as early as 1930. He taught armored tactics to the General Staff aspirants at the War Academy, and he contributed numerous articles on that subject to various military journals. He had led the 2nd Panzer Regiment with considerable distinction in Poland and France. When Hitler cut the strength of the tank divisions in half, Breusing wrote a number of critical articles on the subject. They were published without comment in several military journals, where they attracted the attention of the High Command of the Armed Forces (OKW) staff. Someone took one or more of the articles to Hitler, who had Breusing summarily relieved of his command. Rudolf Sieckenius therefore inherited a very unhappy regiment, and his officers greeted him with guarded hostility and suspicion.

Fortunately for the uncomfortable Sieckenius, his new division commander was the very experienced and competent Hans Valentin Hube. This major general had lost an arm at Verdun in 1916 and, as far as I am able to determine, was the only handicapped officer selected for the Reichsheer. Hube understood the situation and let it be known that he expected his officers to give the new regimental commander their full support and cooperation, and to try to make him feel at home. Sieckenius’s transition was further aided by the rush of events. The division almost immediately moved to its jump-off positions on the west bank of the Bug River. On June 22, 1941, Operation Barbarossa, the German invasion of the Soviet Union, began. The 16th Panzer followed the 11th Panzer Division across the river at Sokol-Krystinopol and was immediately involved in the fierce frontier fighting.

The Russian border area was fortified and strongly defended, but the division fought its way through in a matter of days. Then, from June 27 to July 1, the Red Army counterattacked in almost overwhelming strength, using hundreds of tanks that were mostly superior to the German panzers. The division, however, held its positions and beat back every attack. When the Soviets finally retreated, they left 243 burned-out tanks on the battlefield. Most of them had been destroyed by the 2nd Panzer Regiment. For his part in the victory, Hube personally presented Sieckenius with the coveted Knight’s Cross on July 15.

Sieckenius continued to lead the 2nd Panzer Regiment in the huge battle of encirclement at Uman and the subsequent Russian breakout attempts in and around Monasterischtse and in the dense Oratov Forest (July 25 to August 2). There was no time for rest, however. Sieckenius set off immediately down the meandering Bug and his I Battalion (under Reserve Major Count Hyazinth Strachwitz) seized Pervomaisk by coup de main. The next day, Sieckenius personally led a surprise attack and captured the bridge at Vosnesenk.

The furious pursuit continued until August 6, when the division was checked outside the Black Sea naval base of Nikolaev. The base was screened and the battle turned over to the infantry, which captured it on August 20, while Hube’s division moved north to Kirovograd. Meanwhile, near Novo-Danzig, Soviet forces surprised and captured the 6th Company of the 79th Rifle Regiment. After it surrendered, every man was mercilessly massacred.

News of this atrocity was received with shock and rage by the men of the 16th Panzer Division. Sieckenius and his men had been aware of Hitler’s ‘‘Commissar Order,’’ which had been issued before the invasion began, under which captured Soviet political officers were to be summarily executed as war criminals. Field Marshal Gerd von Rundstedt, the commander of Army Group South, had not made much of an effort to disseminate the order and Colonel General Ewald von Kleist, the commander of the 1st Panzer Group, had ignored it altogether.

His units, including the 16th Panzer Division, had behaved remarkably well—until now. After Novo-Danzig, however, everything was different, and the war became increasingly brutal.

Meanwhile, the recon battalion of the 16th Panzer (Major von Witzleben) seized a bridgehead over the wide Dnieper River near Kremenchug on September 11. The next day, the entire division was across the river and barreling through the rear areas of the Soviet armies defending Kiev and the Ukraine. On September 16, near Lubny on the Sula River, the 16th Panzer Engineer Battalion linked up with Walter Model’s 3rd Panzer Division of Guderian’s 2nd Panzer Group, surrounding more than 700,000 Soviet soldiers. By the time the battle ended on September 26, five Red armies had been destroyed and 667,000 men surrendered, along with 3,718 guns and 584 armored vehicles. Hube’s division was not there for the finish, however. Led by von Witzleben, Strachwitz, and Sieckenius, it was off and running to the southeast, where it played the major role in smashing the Soviet 18th Army around Melitopol. The division found the body of the Russian army commander, General Smirnoff, on October 6. Hube ordered him buried with full military honors.

For his services to date, Rudolf Sieckenius was promoted to colonel on October 1, 1941, with seniority to date from February 1.

The target for the next advance was Rostov, and it was harder. It began on October 12, and was hampered by supply problems and maintenance difficulties. The rainy season set in on October 27 and the division, which had clearly outrun its supply lines, halted. The offensive was not resumed until November 17–18, when the first severe frost hardened the soil. Rostov was captured by the III Panzer Corps on November 20, while the 16th Panzer covered its northern flank.

Stalin’s winter offensive on the southern sector began on November 22—earlier than elsewhere. Hube’s division alone faced 10 Russian divisions. On November 28, in near blizzard conditions, the 1st Panzer Army finally retreated and Rostov was abandoned. Sieckenius and his two battered battalions fell back to the Mius, where the Reds were finally halted. While his regiment huddled in their bunkers near the front, Sieckenius spent much of his time that winter in Stalino, supervising the arrival of new tanks and begging for more.

The summer campaign of 1942 began in June. Hube moved up to the command of the XIV Panzer Corps in September, and Lieutenant General Gunther Angern took over the division, which was then on the Volga and fighting in the northern suburbs of Stalingrad. It was committed to street fighting by the 6th Army commander, Colonel General Friedrich Paulus, who did not seem to understand that armored divisions should not be sent into combat in built-up areas. By mid-November, the division had been reduced to a strength of 4,000 men—about one-quarter of its strength in May 1941.

Finally, on November 20, the 94th Infantry Division completed the relief of the 16th Panzer in the line at Stalingrad, and the depleted division headed west for the Donetz, where it was to undergo a complete refit. Angern instructed Sieckenius to command the vanguard while he personally directed the rearguard. As fate would have it, however, Stalin’s counteroffensive began on November 19. The northern pincher overwhelmed the 3rd Rumanian Army in one day and cut right across the line of march of the 16th Panzer Division on the evening of November 20. The fighting was fierce, but Sieckenius was cut off from the rest of the division on November 21. Sieckenius had the 2nd Panzer Regiment, the I/64th Rifle Regiment, the 16th Panzer Reconnaissance Battalion, most of the 16th Engineer Battalion, and the 16th Tank Destroyer Battalion, which was led by Major Curt von Burgsdorff, a 56-year-old reservist who had volunteered for frontline duty after his only son was killed near Moscow in early 1942. Angern was left inside the pocket with the 79th Panzer Grenadier Regiment, most of the 64th Panzer Grenadier (led by Lieutenant Colonel Dr. Woermann), and the entire 16th Panzer Artillery Regiment (led by Colonel Ernst Strehlke), as well as assorted divisional troops and the staff of the 16th Panzer Brigade under Major General Hans Adolf von Arenstorff.

Sieckenius divided his command into two (later three) combat groups and did yeoman’s service, bolstering and often restoring the thin German line as it was pushed westward, back across the frozen Donetz. Sieckenius was severely wounded in mid-January 1943 and was shipped home to recover. Strachwitz assumed command but was himself seriously wounded two days later, so command devolved on Major Bernhard Sauvant, the former commander of the II/2nd Panzer Regiment, who was the senior surviving officer outside the pocket.

Soon Sauvant would be the senior surviving officer of the division, period. In Stalingrad, the rest of the 16th Panzer Division was crushed. Rather than surrender to the Russians, General Angern committed suicide on February 2, and the ranking surviving officer, Lieutenant Colonel Dr. Woermann, surrendered the remnants of the division that same day.

The forces still with Sauvant were sent back to Stalino and put on trains for France, where the division was to rebuild. Meanwhile, on February 5, 1943, Colonel Sieckenius visited the commander of Wehrkreis II in Stettin and reported for duty. He now wore the Wounded Badge in Silver, which was awarded only after a soldier received his third wound. He was allowed to recover for 10 more days and was then ordered to report to Panzer Troop Command VI Headquarters at Warendorf for reassignment.

After two weeks of light duty, he flew to Mayenne, France, where he replaced Colonel Burkhart Mueller-Hildebrand as commander of the reception staff of the rebuilding 16th Panzer Division. He assumed formal command of the division near Laval on March 5. It initially consisted of 3,400 men who returned from service in Russia and 600 Russian volunteers, who were called ‘‘Hiwis.’’ These were soon joined by thousands of new inductees, and dozens of new tanks, self-propelled guns, artillery, and new Mercedes half-tracks, which were called ‘‘bucket cars.’’

On May 23, General of Panzer Troops Hans Hube—en route to Italy as the commander of the rebuilt XIV Panzer Corps—visited the division to take its salute on the anniversary of the Battle of Mont Morion, which the original 16th Panzer had won in 1940. That evening, Sieckenius and his officers entertained their former commander at dinner at Mayenne, and, as a body, entreated Hube to request their unit be assigned to his corps. It did not take too much pleading.

Hube was one of the very few army generals Hitler respected and trusted throughout the war, so he readily agreed to assign the new division to the XIV Panzer Corps. On May 25, the 16th Panzer began its trip to northern Italy. The infantry went by way of Munich and the Brenner Pass; the heavy equipment traveled via Avignon and Nice. They rendezvoused near Siena in Tuscany in early June. Meanwhile, Rudolf Sieckenius was promoted to major general, effective June 1, 1943.

Hube defended Sicily with the 15th and 29th Panzer Grenadier Divisions and the Luftwaffe’s Hermann Goering Panzer and 1st Parachute Divisions. Meanwhile, on July 25, the 23-year reign of Benito Mussolini ended when he was deposed by the king and was arrested as he left the palace. The new government under Field Marshal Pietro Badoglio hotly proclaimed its loyalty to the Third Reich, but Adolf Hitler knew the Italians were lying. They were just waiting for the right moment to defect.

Sieckenius, meanwhile, moved his division south and deployed every available unit along the Gulf of Salerno, but positioned them about three miles from the beaches, in case the Allies tried to land paratroopers in Hube’s rear. He also kept a wary eye on his Italian counterparts, General Gonzaga’s 222nd Coastal Defense Division. In the meantime, Hube successfully evacuated Sicily. Montgomery’s 8th Army crossed the Straits of Messina on September 3 and invaded the Reggio da Calabria, the toe of the Italian boot.

Hitler was right about the Italians. They surreptitiously signed surrender terms with the Allies at Cassibile, Sicily, but the news was not made public until Wednesday, September 8, when General Mark Clark’s Anglo-American invasion force, the U.S. 5th Army, was already on its way to Italy.

As soon as he heard the news, Sieckenius dispatched his intelligence officer, Major von Alvensleben (who spoke fluent Italian), along with an armed motorized detachment, to General Gonzaga’s headquarters to arrest and disarm the Italian coastal defense division. On the way, Alvensleben found that half of Gonzaga’s men had abandoned their posts and headed for home. Once at HQ, the remaining senior officers surrendered immediately and made no trouble; Gonzaga, however, refused to capitulate. One word led to another, and Alvensleben slapped his holstered Luger as a threatening gesture. Gonzaga at once pulled his service revolver, waved it at the major, and shouted for help, which was not forthcoming. One of Alvensleben’s soldiers, believing that the major’s life was in danger, opened up with his Schmiesser automatic. Gonzaga was killed instantly. Sieckenius saw to it that his body was sent home with appropriate honors.

The 222nd Coastal Defense Division ceased to exist on September 8, and it was not too soon. On September 9, the Anglo-American invasion force landed at Salerno and on its neighboring beaches. Sieckenius pounded the sector with artillery and multiple rocket launchers, while his own units were blasted by the big guns of the Royal Navy and later the U.S. Navy. The 16th Panzer Division began launching counterattacks on September 10.

The Battle of Salerno was hard fought on both sides, and the 16th Panzer gave the Americans some very bad moments. At one point, Sieckenius penetrated almost to the invasion beaches, and Lieutenant General Mark Clark, the commander of the U.S. 5th Army, was contemplating a retreat to his ships. The 16th Panzer was halted in front of the last American defensive line.

Reinforced by battle groups from three other divisions, Sieckenius attempted to launch a massive tank attack on September 16 and 17, but both efforts were aborted when Allied naval guns and airplanes blasted the units in their assembly areas. The Germans began to retreat on September 18. OKW considered that, at the very least, they had won a major prestige victory. Casualties had been very high: almost 7,000 Allies were killed, wounded, or missing. The Germans lost 840 killed, 2,002 wounded, and 630 missing. At least 90 percent of these were from Sieckenius’s division.

Meanwhile, Sieckenius conducted a perfectly orchestrated withdrawal to the Avellino-Olfante line. He personally commanded the rearguard and inflicted heavy damage on the U.S. VI Corps around Teora on September 24–25.

With the German right flank secured, Sieckenius was called to stabilize the left, where Montgomery’s British 8th Army had secured a bridgehead over the Biferno River at Termolin, near the Adriatic coast. The division made a long 95-mile road march along the difficult mountain roads of the Apennines during the night of October 4–5. As a result, it was badly strung out and went into battle against the British piecemeal. In a tough battle against two British armored brigades, Sieckenius lost most of his remaining armor, mainly to British air strikes. Now a burned out unit at kampfgruppe (regimental) strength, the 16th Panzer covered the retreat of the LXXVI Panzer Corps to the north. It was, however, unable to prevent Montgomery’s commandos from seizing a small bridgehead across the Trigno, south of the town of Vesta. The bridgehead was quickly sealed off by the 16th Panzer, and the entire Allied advance was halted by the onset of the rainy season, which turned the entire country into mud.

Meanwhile, Field Marshal Albert Kesselring, the OB South and commander-in-chief of Army Group C, had promised Hitler he would hold the Volturno-Biferno line until at least October 16. He had failed, and now Berlin was demanding scapegoats. For no good reason, Rudolf Sieckenius and the 16th Panzer Division were selected. Sieckenius was relieved of his command on October 31, 1943, and his career was ruined.

How Hitler, OKW, and OKH could have found any legitimate cause for dissatisfaction with the performance of the 16th Panzer is impossible to understand. It fought the Battle of Salerno almost singlehandedly and, despite the tremendous odds against it, narrowly failed to throw the Americans back into the sea. It then checked the U.S. VI Corps at Teora and, after a difficult forced march, stabilized the German left flank against greatly superior British forces. In the process, it lost more than half of its men and most of its tanks and artillery.

Despite its truly heroic efforts, however, the divisional history records that not one member of the 16th Panzer Division was awarded the Knight’s Cross or the German Cross in Gold in September or October
1943!

General Sieckenius was placed in Fuehrer Reserve in Kassel, Wehrkreis IX, and his rank was permanently frozen. He was forced to take a course in National Socialist Leadership Procedure, as well as the short Division Commanders’ Course, which was given only to officers who had been earmarked to command a division but had not yet done so (unless it was briefly and on a temporary basis only). This was an insult, because he had already commanded a division in combat and had done so with considerable skill. Thoroughly bewildered and frustrated, he was unemployed until February 21, 1944, when he was ordered to report to the Army Personnel Office in Berlin. He was attached to the 1st Bureau as a reserve division commander. A month later, he was sent to Army Group North in Russia for use as a backup division commander, to be used if a regular divisional commander went on leave, was wounded, or was killed.

Sieckenius hung around headquarters until May 2, when Lieutenant General Konrad Heinrichs, the commander of the 290th Infantry Division, went back to Germany on leave. Sieckenius defended a sector near Lake Ladoga until May 23, when General Heinrichs returned. Meanwhile, on May 21, Lieutenant General Werner Richter, the commander of the 263rd Infantry Division, was mortally wounded while defending a sector on the Duna River. Although unacquainted with static (completely unmotorized) units, Sieckenius took command at once and directed the division in a skillful retreat to the Dvina during the massive Soviet offensive of June–July 1944.

Sieckenius led the 263rd Infantry until August 14, when Major General Adolf Hemmann arrived to replace him. Next, he was sent to Breslau, to supervise the dissolution of the 221st Security Division, which had been smashed by Stalin’s massive offensive of June–July 1944. (The permanent commander, Major General Hubert Lendle, had committed the sin of escaping death or capture, so he had been summarily dismissed.) General Sieckenius completed this unpleasant task by August 31.

Meanwhile, the 391st Field Training Division was reforming in Breslau as a security division. It had been smashed in the Minsk-Bobruisk encirclements, and its previous commander, Lieutenant General Baron Albert Digeon von Monteton, had been transferred to Army Group North as the commandant of Lerpaja (Libau), and Rudolf Sieckenius was selected to replace him.

Sieckenius’s new command included the 312th Field Training and 566th Security Regiments. The men were mainly overage volunteers or draftees, rear-area personnel (including bakers, typists, clerks, postal people, maintenance personnel, and so on), and returning wounded. The 312th consisted of rear-area veterans of the defunct 206th Infantry Division, which had been destroyed at Bobruisk. Its commander had a serious health problem and would have been sent home, except for his determination to continue soldiering. The commander of the 566th was a 62-year-old reserve officer who had commanded the supply depot at Pinsk until it was captured by the Red Army. With one or two exceptions, all of the officers were from the noncombatant branches. Sieckenius had no artillery, no heavy weapons companies, and no signal, engineer, or reconnaissance units. Worse yet, he did not have any horses to speak of—much less motorized vehicles!

Sieckenius made the best of a bad situation and instituted a rigorous training regimen, including a physical fitness program. Unlike the typical security or field training division in 1944–45, the 391st was not raided for trained men and replacements for regular combat units because of the need for a permanent defensive force at Breslau and on the southern reaches of the Oder River.

Meanwhile, in December 1944, Sieckenius was eligible for promotion to lieutenant general. He was summarily passed over.

In late January 1945, the Soviets launched another massive offensive. Sieckenius had done such a marvelous job that the 391st Security Division was now actually considered a potentially battle-worthy unit. The 9th Army, which was responsible for defending the lower Oder, allocated Sieckenius a fleet of ancient trucks, as well as replacement and training companies of signal troops and engineers, heavy machine guns, and two batteries of self-propelled artillery. With these reinforcements he hurried to the Oder, where he joined the V SS Panzer Corps, which was holding the river from Guben to Eberswalde, on the right flank of the 9th Army.

The V SS Panzer Corps was not a panzer corps and did not have a single tank unit! It was commanded by SS Lieutenant General Friedrich-Wilhelm Krueger, who was soon replaced by SS Lieutenant General Friedrich Jeckeln, a mass murderer who had commanded an Einsatzgruppen (an SS murder unit) in 1941.

The last Soviet offensive began on April 16. Its objective was Berlin. Despite overwhelming odds, the German line held until April 19; then it broke, and the 9th Army was cut in two. The LVI Panzer and the two security divisions of the V SS Corps were pushed back to the north, on Zepernick and Ladeburg, while the rest of the army was in danger of being encircled behind the Spree River, between Erkner and Zossen. Sieckenius and Major General Emmo von Roden, the commander of the 286th Security Division, lost contact with the Headquarters, V SS Corps, and more or less by default placed themselves under the command of General of Artillery Helmuth Weidling, the commander of the LVI Panzer Corps. Weidling found himself named Battle Commandant of Berlin on April 25, the day the city was surrounded.

The remnants of the 391st Security Division were incorporated into the defensive perimeter of the capital. Initially, Sieckenius’s forces held positions along the Landwehr Canal, supporting SS Major General Joachim Ziegler’s SS Nordland Division. Weidling, however, considered Ziegler a worn-out force, so he replaced him with SS Major General Gustav Krukenberg, whose 33rd SS Grenadier Division ‘‘Charlemagne’’ had virtually ceased to exist. He placed Sieckenius in charge of the entire sector.

During the next three days, Sieckenius tried to hold his positions while the German defensive lines were pressed ever backward, toward the center of the city.
