Anton Ludwig Friedrich August Mackensen (ennobled asvon Mackensen in 1899; 6 December 1849 – 8 November 1945), was a Germanfield marshal.^[2] He commandedArmy Group Mackensen duringWorld War I (1914–1918) and became one of theGerman Empire's most prominent and competent military leaders. After thearmistice of 11 November 1918, the victoriousAllies interned Mackensen inSerbia for a year. In 1920, he retired fromthe army. In 1933Hermann Göring made him aPrussian state councillor. During theNazi era (1933–1945), Mackensen remained a committedmonarchist and sometimes appeared at official functions in his World War I uniform. SeniorNazi Party members suspected him of disloyalty, but nothing was proven against him.

Mackensen was born in Haus Leipnitz, near the village of Dahlenberg (today part ofTrossin) in thePrussianProvince of Saxony, to Ludwig and Marie Louise Mackensen. His father, an administrator of agricultural enterprises, sent him to aRealgymnasium inHalle in 1865, seemingly in the hope that his eldest son would follow him in his profession.^[3]

Mackensen began his military service in 1869 as a volunteer with the Prussian 2nd Life Hussars Regiment (Leib-Husaren-Regiment Nr. 2). During theFranco-Prussian War of 1870–1871, he was promoted to second lieutenant and won theIron Cross Second Class for leading a charge on a reconnaissance patrol north ofOrléans.^[4] After the war, he left the service and studied atHalle University but returned to theGerman Army in 1873 with his old regiment.

He married Doris (Dorothea) von Horn, the sister of a slain comrade, in 1879. Her father,Karl von Horn [de], was the influentialOberpräsident ofEast Prussia. They had two daughters and three sons. He found a mentor from the War MinisterJulius von Verdy du Vernois.^[5] In 1891, Mackensen was appointed to theGeneral Staff in Berlin and bypassed the usual three-year preparation in the War Academy. His chief,Helmuth von Moltke, found him a "lovable character".^[6]

Mackensen was recalled from the regiment to serve as an adjutant to the next chief,Alfred von Schlieffen (in office 1891–1906), whom he regarded as a great instructor on how to lead armies of millions.^[7]

Mackensen impressed KaiserWilhelm II, who ordered that Mackensen be given command from 17 June 1893 of the 1st Life Hussars Regiment (Leib-Husaren-Regiment Nr. 1) to which he becameà la suite when he left its command on 27 January 1898 and so he often wore the distinctivedeath's head uniform thereafter.^[8] Mackensen was surprised by his next posting, as adjutant to Wilhelm II because he was the first commoner to hold that position. For the next three-and-a-half years, he shadowed the Kaiser and met the high and mighty of Germany, the rest of Europe and the Middle East. His sons were schooled with the Kaiser's. Mackensen was ennobled on the Kaiser's 40th birthday, 27 January 1899, and becameAugust von Mackensen.^[9]

Next, he received the command of the newly created Life Hussar Brigade (Leib-Husaren-Brigade) from 1901 to 1903, and from 1903 to 1908, he commanded the36th Division inDanzig.^[10]

His wife died in 1905, and two years later, he married Leonie von der Osten, who was 22 years old. When Schlieffen retired in 1906, Mackensen was considered as a possible successor, but the position went toHelmuth von Moltke the Younger. In 1908, Mackensen was given command of theXVII Army Corps, headquartered inDanzig.^[11] TheCrown Prince was placed under his command, and the Kaiser asked Mackensen to keep an eye on the young man and to teach him to ride properly.^[12]

At the outbreak of war in 1914, Mackensen, aged 65, commanded theXVII Army Corps, which became part of theGerman Eighth Army in East Prussia, under GeneralMaximilian von Prittwitz, and then, 21 days later, under GeneralPaul von Hindenburg. Mackensen had his corps moving out on a 25 km march to theRominte River within fifty minutes of receiving his orders on the afternoon of 19 August 1914, after theImperial Russian Army hadinvaded East Prussia.^[13] He led the XVII Corps in the battles ofGumbinnen (20 August 1914),Tannenberg (23 to 30 August 1914) and theFirst Battle of the Masurian Lakes (2 to 16 September 1914), which drove the invading Russians out of most of East Prussia.

On 2 November 1914, Mackensen took over command of theNinth Army from Hindenburg, who became Supreme Commander East (Oberbefehlshaber Ost). On 27 November 1914, Mackensen was awarded thePour le Mérite, Prussia's highest military order, for successful battles aroundWarsaw andŁódź.

By April 1915, the Russians had conquered much of westernGalicia and were pushing towardHungary. In response to the desperate pleas from Vienna, German Chief of StaffErich von Falkenhayn agreed to an offensive against the Russian flank by an Austro-German army under a German commander. The reluctant Austro-Hungarian supreme command agreed that the tactful Mackensen was the best choice for commanding the coalition army.Army Group Mackensen (Heeresgruppe Mackensen) was established, containing a new GermanEleventh Army, also under his command, and the Austro-Hungarian Fourth Army. As chief of staff, he was assignedHans von Seeckt, who described Mackensen as an amiable, "hands-on commander with the instincts of a hunter".^[14] His army group, which had an overwhelming advantage inartillery, smashed through the Russian lines betweenGorlice and Tarnow and then continued eastward. Never giving the Russians time to establish an effective defence, it retook most of eastern Galicia, recapturingPrzemyśl andLemberg.^[15] The joint operation was a great victory for theCentral Powers, which advanced 310 km (186 mi), and the Russianspulled out of all of Poland soon afterward.

Mackensen was awarded oak leaves to hisPour le Mérite on 3 June 1915 and was promoted tofield marshal on 22 June. He also received theOrder of the Black Eagle, Prussia's highest-ranking order of knighthood, as well as numerous honours from other German states – including the Grand Cross of theMilitary Order of Max Joseph, the highest military honor of theKingdom of Bavaria, on 4 June 1915 – and from Germany's allies.

In October 1915, a newArmy Group Mackensen (Heeresgruppe Mackensen, which included theGerman Eleventh Army, theAustro-Hungarian Third Army and theBulgarian First Army), launched a renewed campaign againstSerbia. The campaign crushed effective military resistance in Serbia but failed to destroy theRoyal Serbian Army, half of which managed toretreat to Entente-held ports in Albania and, after recuperation and rearmament by the French and the Italians, re-entered fighting on theMacedonian front. When Mackensen returned to Vienna, he was honoured by a dinner and a personal audience with EmperorFranz Joseph I of Austria and was decorated with the magnificently jeweledMilitary Merit Cross 1st Class with Diamonds, a unique award for a foreigner.

Mackensen appears to have had great respect for the Serbian Army and Serbs generally. Before departing to the Serbian front in 1915, he had spoken to his men:^[16]

You are not going to the Italian, Russian, or French front. You are going into battle against a new enemy - dangerous, tough, fearless, and sharp. You are going to the Serbian front and Serbia. Serbs are people who love their freedom, and who will fight to the last man. Be careful this small enemy does not cast a shadow on your glory and compromise your successes.^[16]

AfterRomania declared war on Austria-Hungary on 15 August 1916, Mackensen was given command of a multinational army, with General Emil von Hell as chief of staff, ofBulgarians,Ottomans, Austro-Hungarians and Germans. It assembled in northern Bulgaria and then advanced intoDobruja. By 8 September,it had taken the two major forts on the right bank of the Danube, the first in a single day by a force that was outnumbered by the besieged, who were overwhelmed by Mackensen's artillery.^[17] Then, a German and Austro-Hungarian army group that was commanded by Falkenhaynbroke into Wallachia through theVulkan Pass in the Transylvanian Carpathian Mountains while Mackensen crossed the Danube by seizing bridgeheads on the left bank to shield the Austro-Hungarian engineers who built the long pontoon bridge. The Romanian Army and its Russian allies were forced back between those pincers. After three months of war, two thirds of Romania was occupied by the Central Powers. The capital of Romania,Bucharest,was captured by the Central Powers on 6 December 1916, on his 67th birthday. He rode in on a white horse and moved into the Romanian royal palace.^[18] For that performance, on 9 January 1917, Mackensen was awarded theGrand Cross of the Iron Cross and became one of only five recipients of that honour in the First World War. Since he now wore every Prussian medal, the Kaiser decided to name a battle cruiser after him, which became the first in anew class.^[19] Mackensen became the military governor of the large part of Romania (mainlyWallachia) that was occupied by the Central Powers. He proposed making a German prince the King of Romania, but the initiative fell through. His last campaign was an attempt to destroy the Romanian Army, which had been reorganised.

During theBattle of Mărăşeşti, both sides took heavy losses, but the Romanian Army emerged victorious. Mackensen maintained that he had never been defeated in battle, and he surely was the most consistently successful senior general on either side in World War I. By December 1917, the Russian Army had collapsed, and the Romanian Armed Forces were forced to sign theArmistice of Focșani, followed by theTreaty of Bucharest.

On 11 November 1918, Germany signed anarmistice with the Allies under which it had to immediately withdraw all German troops inRomania, theOttoman Empire,Austria-Hungary and theRussian Empire back to German territory and Allies to have access to those countries.^[20]

After the armistice, he and the 200,000 men he led back home were rounded up. He was arrested by the agents of the pro-Entente Hungarian leaderMihály Károlyi inBudapest. Mackensen was held in a guarded villa at the edge of Budapest.^[21] Later, he was handed over to the representatives of GeneralLouis Franchet d'Espèrey's Allied army. He was a military prisoner inFutog, Serbia, until November 1919.^[22] He was one of the 896 Germans on the Allied list of accused war criminals, which was eventually allowed to lapse.

By 1920, Mackensen had retired from the army. Although standing in opposition to the conclusion of theTreaty of Versailles and the newly establishedparliamentary system of theWeimar Republic, he initially avoided public campaigns. Around 1924, he changed his mind and began to use his image as a war hero to supportmonarchist andnationalist groups. He routinely appeared in his old Life Hussars uniform. He became very active in pro-militaryConservative Revolutionary movement organisations, particularlyDer Stahlhelm and the Schlieffen Society, which advocated thestab-in-the-back myth and openly endorsed the murder of MinisterMatthias Erzberger in 1921.

During theGerman presidential election of 1932, Mackensen supportedPaul von Hindenburg againstAdolf Hitler, whose political skills he nevertheless admired.

After Hitler gained power in January 1933, Mackensen became a visible, if largely symbolic, supporter of theNazi regime. A striking visual icon of thePrussian traditions adopted by Hitler's regime, he appeared in his black uniform and death's-headbusby at public events organized by the German government or theNazi Party such as theDay of Potsdam on 21 March 1933. On 26 August 1933, PrussianMinister PresidentHermann Göring appointed Mackensen to the recently reconstitutedPrussian State Council.^[23] In 1935, he stood by Hitler's side for the ceremonies of the March 16Heldengedenktag, or Heroes' Memorial Day, celebrating Hitler's public announcement that Germany would cease to comply with theTreaty of Versailles, and would openly re-arm.^[24] One of Mackensen's ceremonial visits brought him toPassau, where he received a hero's welcome.^[25]

Excellency, the gravity of the moment has compelled us to appeal to you as our Supreme Commander. The destiny of our country is at stake. Your Excellency has thrice before saved Germany from foundering, at Tannenberg, at the end of the War and at the moment of your election as Reich President. Excellency, save Germany for the fourth time! The undersigned Generals and senior officers swear to preserve to the last breath their loyalty to you and the Fatherland

— closing of the letter to von Hindenburg

Von Mackensen was, however, appalled by the murder of his friend GeneralKurt von Schleicher and GeneralFerdinand von Bredow in theNight of the Long Knives at the end of June 1934 and said so. He (with others) signed a letter to Presidentvon Hindenburg on 18 July detailing the brutal murder of von Schleicher and his wife, and noting that von Hindenburg's friendFranz von Papen had barely escaped with his life.^{[citation needed]} His letter demanded that von Hindenburg punish the responsible parties and create a directorate to rule Germany. He started a campaign to have von Schleicher rehabilitated by Hitler and, when this gathered strength and succeeded, spoke about the murders at the annual General Staff Society meeting in February 1935.^{[citation needed]}

Von Mackensen did not, however, blame Hitler personally but rather some his more radical subordinates, probably wished Hitler to be retained as Chancellor under the suggested Directorate, and continued to stand by the regime.

Occasionally mocked as the "Reich Centrepiece", Mackensen's ferocious soldier's visage and distinctive public profile in his black Life Hussars uniform was even recognised by the Hausser-Elastolin company, which produced a 7 cm figure of him in its line ofElastolin composition soldiers.^[26] His fame and familiar uniform gave rise to two separate Third Reich units adopting black dress withTotenkopf badges: thePanzerwaffe, which claimed the tradition of the Imperial Cavalry, and theSchutzstaffel. In October 1935, the government vested Mackensen with thedemesne ofBrüssow inBrandenburg in recognition of his merits.

In spite of the implicit endorsement provided by his public appearances with high-ranking Nazi officials, Mackensen's relationship to the Nazis was not fully approving: besides the killing of von Bredow and von Schleicher, he also objected to the NaziKirchenkampf measures against theConfessing Church and to the atrocities that were committed during theinvasion of Poland in September 1939.

On 4 February 1940, Mackensen wrote to then GeneraloberstWalther von Brauchitsch:

As a man becomes older, he has to watch carefully that age has not reduced his creativity. After reaching the age of 90, I have decided not to involve myself any longer with matters that are not concerned with my private life. However, I am still the most senior German officer. Many turn to me, sometimes with wishes but more often with their concerns.

During these weeks, our concern is with the spirit of our unique and successful Army. The concern results from the crimes committed in Poland, looting and murder that take place before the eyes of our troops, who appear unable to put an end to them. An apparent indifference has serious consequences for the morale of our soldiers, and it is damaging to the esteem of our Army and our whole nation.

I am sure that you are aware of these events and that you certainly condemn them. These lines intend to convey my daily growing concern at the reports that constantly reach me, and I have to ask you to take up this matter with the highest authority. The messages I receive are so numerous, many come from high ranking persons and from witnesses. As the most senior officer, I cannot keep them to myself. In transmitting them to you, I fulfil my duty to the Army. The honour of the Army and the esteem in which it is held must not be jeopardised by the actions of hired subhumans and criminals. Hail Victory (Sieg Heil).^[27]

By the early 1940s, Hitler andJoseph Goebbels suspected Mackensen of disloyalty but refrained from taking action.^[28] Mackensen remained a committed monarchist and in June 1941 appeared in full imperial uniform atKaiser Wilhelm's funeral atDoorn, in theNetherlands.^[29]

Hitler personally congratulated Mackensen on his 95th birthday in December 1944 and awarded the 5th cavalry regiment with the armband "Field marshal von Mackensen".^[30]

According to a radio news report dated 15 April 1945 that was filed by theCBS News correspondentLarry LeSueur for World News Today, Mackensen was briefly captured by the BritishSecond Army at his home during the closing weeks of theSecond World War. Upon the arrival of the British, not commenting on the general rout, the 95-year-old Mackensen merely asked the new powers-that-be that "freed foreign workers" be prevented "from stealing his chickens".^[31]

Mackensen died on 8 November 1945 at the age of 95, his life having spanned theKingdom of Prussia, theNorth German Confederation, theGerman Empire, theWeimar Republic, theNazi regime and the postwarAllied occupation of Germany. He was buried in theCelle cemetery.

In November 1879, Mackensen married Dorothea von Horn (1854–1905), and they had five children:

• Else Mackensen (1881/2–1888)
• Hans Georg von Mackensen (1883–1947), diplomat
• Manfred von Mackensen (1886–1947)
• Eberhard von Mackensen (1889–1969),Generaloberst, German Army
• Ruth von Mackensen (1897–1945)

In 1908, after the death of his first wife, Mackensen married Leonie von der Osten (1878–1963).

Mackensen and his family wereLutheranProtestants in theEvangelical Church of Prussia.

Mackensen was an Honorary Citizen of many cities, such asDanzig,Heilsberg,Buetow, andTarnovo. In 1915, the newly built rural village of Mackensen inPomerania was named after him. In various cities, streets were named after him. In 1998 theMackensenstraße in theSchöneberg district of Berlin was renamedElse-Lasker-Schüler-Straße, based on a claim that Mackensen was one of the "pioneers of National Socialism".^[44]
