He was decorated with the Pour le Mérite with Oakleaves, Prussia's highest award for military valor.

He was the son of the later Prussian Lieutenant General Julius Heinrich von Boehn (1820–1893) and his wife Luise Henriette Josepha, née Cords (17 November 1830 Mischwitz at Hohensalza − 19 August 1883 in Berlin).

[1] During the Franco-Prussian War of 1870–1871, Boehn participated in the Sieges of Metz, Toul, and Paris as well as the battles at Dreux, Bellême and partially at La Madeleine-Bouvet.

[1] On 22 June 1882, he was made à la suite of 4th Regiment of Foot Guards while remaining in his assignment as brigade adjutant.

[1] On 1 August 1882, Boehn was promoted to supernumary Hauptmann (captain) and on 14 October, he was transferred to the Kaiser Alexander Guards Grenadier Regiment No.

On 22 April 1905, Boehn was promoted to Generalleutnant (lieutenant general) and named commander of the 18th division in Flensburg.

[1][2] King Wilhelm II of Württemberg awarded him the Grand Cross of the Friedrich Order in June 1911.

[3] On 21 September 1912, Boehn was retired with pension and named à la suite of Infantry Regiment Hamburg (2nd Hanseatic) No.

[5] Called the "North Army," its first duty was protecting the coast in Schleswig-Holstein, as well as the strategically important Kaiser Wilhelm Canal, from a possible invasion, until 22 August 1914.

[5] On 25 August in Leuven, units under his command were involved in skirmishes with Belgian francs-tireurs that would later be reported as war crimes.

[5][6] Battles followed near Mechelen and around the Fortress Termonde, until major formations came to the aid of the beleaguered army's right wing from Saint-Quentin.

Reporting to the re-formed 1st Army on 19 July 1916, the IX Reserve Corps participated in the Battle of the Somme.

For the defensive success of his troops in the fighting, Boehn was decorated with the Pour le Mérite, Prussia's highest award for military valor, on 24 August 1916.

After heavy fighting on the Chemin des Dames and repeatedly foiling attempts by French forces to break through, Boehn was decorated on 20 May 1917 with the Oakleaves to the Pour le Mérite.

[8] The Kaiser also honored him with the award of the Grand Cross of the Order of the Red Eagle with Oakleaves and Swords.

[9] On 22 March 1918, at the beginning of German spring offensive or Kaiserschlacht in France, Boehn was promoted to Generaloberst (Colonel General).

On 27 May, he was able to proceed aggressively again, overcoming the Chemin des Dames, the Aisne-Marne Canal, the Aisne and the Vesle.

Within days, Boehn's units had achieved territorial gains of 60 kilometres (37 mi) depth, captured 60,000 prisoners of war and seized 830 artillery pieces and 2,000 machine guns.

After fighting in the Antwerp–Meuse position, the cease fire ending the war was proclaimed on 11 November 1918 at Compiègne.

Four children were born: After the First World War, the Treaty of Versailles reduced the German army and caused the city of Hamburg to be demilitarized for nearly 15 years.

During World War II, the barracks, besides its military uses, also housed a hospital for the civilian population of Hamburg.

Only the monument at Dammtor, a memorial stone in the Boehn-Kaserne opposite the former headquarters building of Panzergrenadierbrigade 17, and a bronze relief on the officer's home, remain to commemorate Infantry Regiment No.
