Royal Prussian Jagdstaffel 12 was created on 28 September 1916 from an existing ad hoc unit, Fokkerstaffel West. The new squadron mobilized on 12 October 1916 at Laon, France. It scored its first victory on 4 December 1916. The squadron was initially equipped with ill-performing Fokker D.Is. On 24 March 1917, the unit was credited with its tenth victory. The following month, Bloody April 1917, Jasta 12 downed 23 Royal Flying Corps aircraft. May saw 10 more victories. By the end of July, the jasta's scoreboard showed 74 victories. When it lost its ace commander, Adolf von Tutschek, to wounds, its new Staffelfuhrer led it to 22 victories in three months with no German losses. By the time it joined Jagdgeschwader II on 2 February 1918, Jasta 12 was a seasoned unit with 104 confirmed victories to its credit. However, the new JG II would have equipment problems as German supplies declined. On 26 May 1918, the jasta would find itself temporarily grounded by lack of aircraft. Jasta 12 fought through the end of the war, disbanding only after Germany's loss. The squadron was credited with 155 aerial victories, including three enemy observation balloons. In turn, they suffered 17 killed in action, 8 wounded in action, and one taken prisoner of war.
became the first ace in the squadron, on 24 March 1917. Three of the squadron's commanders, Adolf von Tutschek, Victor Shobinger, and Hermann Becker, were notable as aces as well as Staffelnführer. Also notable among the unit's fourteen aces were: Ulrich Neckel, winner of the Pour le Merite and Iron Cross; Reinhold Jörke, another Iron Cross awardee; and Paul Billik, an Iron Cross and Hohenzollern winner who was the highest scoring ace to be denied a Pour le Merite.
Aircraft
Jasta 12 operated Fokker D.I, Albatros D.III, Fokker Dr.I, and Fokker D.VII fighter aircraft. Originally, the common squadron paint scheme was black tails and rear fuselages with white propeller spinners and/or engine cowlings. Jasta 12 joined Jagdgeschwader II in February 1918. Identifiable by serial number or pilot insignia, these are some of the aircraft known to have served with the squadron:
Two Albatros D.Vs
Five Fokker Dr.Is
Three Fokker D.VIIs
One Halberstadt CL.II
One Pfalz D.III
One Siemens-Schuckert D.III
One Siemens-Schuckert D.IV
However, during 1918, aircraft were in short supply despite JG II's hoarding of worn Fokker Dr.I triplanes. The withdrawal of newly issued Siemens-Schuckert D.IIIs led to shortages. In the worst instance, on 26 May 1918, Jasta 19 was temporarily grounded because it had no aircraft.
Operations
Jasta 12 was formed in support of 7th Armee. On 4 November 1916, it was transferred to the 1st Armee sector. On 26 January 1917, it moved to service in the Armee-Abteilung A Sector. Shortly thereafter, it moved back to support of 1st Armee. Jasta 12 was one of the squadrons forming Jagdgeschwader II on 2 February 1918, joining Jasta 13, Jasta 15, and Jasta 19 in the new fighter wing.
