[8] He was Regimentschef of the 23rd Prussian Infantry Regiment,[7] recipient of the Kingdom of Prussia's highest military order of merit for heroism, Knight of the Order of Pour le Mérite,[4] Knight of the Order of the Black Eagle,[3] Canon (German: Domherr) of Havelberg,[4] Castellan (German: Drost) in Neuenrade in the County of Mark,[6] Lord Seneschal (German: Amtshauptmann) of Zinna,[6] President of the Ober-Collegium Sanitatis in Berlin and Lieutenant governor of Breslau.

[7] In 1851, his name was place on the north facing commemorative plaque on the Equestrian statue of Frederick the Great in Berlin.

Unlike his father and his eldest brother, choosing to not abjure from his Calvinist beliefs, he left his native Béarn in France for Brandenburg-Prussia, where Frederick I of Prussia, then Elector of Brandenburg, was not only encouraging, but actively facilitating, Huguenot immigration.

[15] The lives and careers of both Friedrich Wilhelm Quirin von Forcade de Biaix and his father are intricately linked to the history of the 23rd Prussian Infantry Regiment, founded in 1713 and disbanded in 1806.

Forcade entered Prussian military service in 1713[16][6] during the reign of King Frederick William I of Prussia (1713–40), beginning what would become one of the most notable military careers in the history of the Kingdom of Prussia, spanning some 53 years,[17] and further serving under King Frederick the Great (1740–65).

He fought at the Siege of Stralsund[16][18] (15 June 1715 - 23 December 1715), where he was wounded for the first time, the storming of the Peenemuende Lair (21–22 August 1715) and on Rügen Island (16–18 November 1715).

The regiment lost its Regimentschef, Major General Wolf Alexander Ernst Christoph von Blanckensee, at the Battle of Soor.

[18][17] King Frederick the Great attributed the glory of the victory to him for his actions on the battlefield that day,[4][18][17] and, on 6 January 1746, awarded him the Kingdom of Prussia's highest order of merit, the Pour le Mérite,[4][8][18][7][9] as well as a pension of 600 Thaler[4][8][18][7][9] and the title of Canon (Domherr) of Havelberg.

During a ritual presentation at court at the Berlin Palace, Forcade had to lean on a window because of his wounded right foot.

I have awarded the vacant {command of} the Bremen Grenadier Company in Golz' Regiment to his eldest son, who is my Adjutant, because he well deserves it".

"Das Regiment Forcade (hat nie ein Feind besiegt)" (lyrics by Georg von Kries, melody by Hans Hertel, 1906) was long a standard, at times mandatory, composition in the German military song repertoire.

Following his death in 1765, his widow received a handwritten letter[18] in French from King Frederick the Great, praising him.

[citation needed] In 1851, General von Forcade was immortalized on the north facing commemorative plaque on the Equestrian statue of Frederick the Great in Berlin.

[30] The rich baron and his family had left Paris after the collapse of John Law's Mississippi Company in 1720 and befriended King Frederick William I of Prussia.
