Étienne Deprez-Crassier

Deprez-Crassier was promoted maréchal de camp (brigadier general) on 1 March 1791.[1] While leading 600 troops, he fought a skirmish with the Prussians at Fontoy on 19 August 1792. His detachment consisted of two companies of grenadiers and five squadrons of Chasseurs à Cheval. His soldiers encountered a superior force of five squadrons of the Wolffradt Hussar Regiment and were defeated with a loss of 200 killed and wounded plus 24 men captured.[2] Nevertheless, he was promoted to lieutenant general on 5 September 1792.[1]

During the Battle of Valmy on 20 September 1792 Deprez-Crassier led a detachment in François Christophe Kellermann's Army of the Centre. Under his command were the 1st Battalion of the 1st Line Infantry Regiment, one grenadier battalion, three squadrons each of the 3rd Hussar and 1st Chasseurs à Cheval Regiments and two squadrons of the 4th Dragoon Regiment.[3] The day before the battle Kellermann sent the Advance Guard under Deprez-Crassier forward from his camp at Dommartin-la-Planchette toward Somme-Bionne.[4] At his position at the La Lune tavern, Deprez-Crassier was joined the next morning by the Reserve under Jean-Baptiste Cyrus de Valence. As the Prussians advanced on his position Kellermann decided to move his main force to the mound of Valmy under cover of a morning fog and the forces of Deprez-Crassier and Valence. During this time three squadrons of Prussian hussars blundered into the covering force and were repulsed. As the Prussians brought up their artillery to fire on the La Lune position, Kellermann established his defensive lines at Valmy. Coming under fire, Deprez-Crassier and Valence fell back to take post near the hamlet of Orbeval on the left of the main position at Valmy. At this time Charles François Dumouriez sent forward nine battalions from the Army of the North to reinforce Kellermann's left flank, 16 battalions to buttress his right and another 12 battalions and six squadrons to form a reserve. When the fog lifted the Prussian generals were surprised to see the French army arrayed in great strength before them.[5] The famous artillery duel followed, after which the Prussian commander Charles William Ferdinand, Duke of Brunswick-Wolfenbüttel declined to press home the attack.[6]
