Eustache Charles d ' Aoust Eustache Charles Joseph d ' Aoust ( 27 February 1763 , Douai – 2 July 1794 , Paris ) was a general officer during the French Revolutionary Wars . He started his military career in the Old Regime army and served on the staffs of three of the early army commanders and later fought in the War of the Pyrenees against the Kingdom of Spain . On three separate occasions he commanded the Army of the eastern Pyrenees , but he shared the fate of two previous commanders when he was arrested and guillotined by the Committee of Public Safety . Early career . Son of Eustache Jean - Marie D ' Aoust , who later became a member of the National Convention , Eustache Charles d ' Aoust began his military career as a second lieutenant supernumerary without pay in the " Royal " Regiment of Infantry on 21 April 1778 at the age of 15 . He became " sous - lieutenant " on 14 April 1782 , second lieutenant on 23 April 1786 , and first lieutenant on 16 August 1789 . On May 26 , 1790 , d ' Aoust was appointed aide - de - camp to Marshal Jean - Baptiste Donatien de Vimeur , comte de Rochambeau . He became captain and adjutant to Marshal Nicolas Luckner on May 21 , 1792 . He became aide - de - camp to General Duc de Biron on 13 July 1792 , and received promotion to colonel on 7 October . Eastern Pyrenees . D ' Aoust was provisionally appointed general of brigade ( BG ) in the Army of the eastern Pyrenees on 2 June 1793 . He was provisionally appointed general of division ( MG ) by representatives Joseph Fabre and Reymond Gaston on 7 August , and assumed command of the camp near Perpignan . This was a difficult time to be a general in the eastern Pyrenees . The Spanish army captured the " Fort de Bellegarde " , a major fortress , when the siege ended on 24 June . Previous commander BG Claude Souchon de Chameron was in prison and MG Louis - Charles de Flers joined him when he was arrested on 6 August . Both Souchon and de Flers were guillotined in 1794 during the Reign of Terror . To make matters worse , the Spanish commander Captain General Antonio Ricardos was a capable opponent . Believing that Ricardos ' Spanish army was unstoppable , MG Hilarion Paul de Puget - Barbantane moved his headquarters well to the rear on 4 September 1793 , putting d ' Aoust in charge of Perpignan . On 11 September , Barbantane fled to Toulouse , leaving the Army of the eastern Pyrenees without a commander . The army briefly separated into three independent divisions and d ' Aoust took command of the 1st Division . On 17 September , d ' Aoust won a significant victory at the Battle of Peyrestortes . He led his troops in an attack on Lieutenant General ( LG ) Juan de Courten ' s 6 , 000 Spanish soldiers at the Camp of Vernet . Other French troops attacked Peyrestortes hill , where LG Jerónimo Girón - Moctezuma , Marquis de las Amarilas deployed his division . For the first time in this theater , the French inflicted a major defeat on their opponents . Spanish killed , wounded , and captured numbered at least 1 , 702 , and 26 cannon were captured . More importantly , the Spanish never seriously threatened Perpignan again . On 18 August , d ' Aoust became subordinated to MG Luc Siméon Auguste Dagobert , the new army commander . A few days after the French defeat at the Battle of Truillas on 22 September , Dagobert was arrested and d ' Aoust became the army commander . On 3 October , d ' Aoust with 16 , 000 men engaged Ricardos and 15 , 000 Spanish troops at Le Boulou on the Tech River . The Spanish won the battle , inflicting losses 400 killed and 800 wounded on their enemies , while suffering only 300 casualties . During and after the battle , 1 , 500 French soldiers deserted . Between 11 October and 21 November , MG Louis Marie Turreau became the new army commander and d ' Aoust went back to command the 1st Division . D ' Aoust temporarily led the army again from 22 to 27 November until the inept but politically influential MG François Amédée Doppet took command from 28 November to 20 December . On 7 December , d ' Aoust advanced with 10 , 000 troops to surprise the enemy camp at Villelongue - dels - Monts . Ricardos with 3 , 000 Spanish and 5 , 000 Portuguese soldiers , repulsed the French attack . The French counted 340 killed and wounded , and 312 missing . In addition , 26 cannon , 2 colors , and 2 , 000 musket s were captured by the Allies . The Allies reported only 56 casualties . Execution . This time , d ' Aoust ' s luck had run out . Though he again assumed temporary army command on 21 December , he was recalled to Paris the next day . On 2 January 1794 , Representatives Jacques Cassanyès and Gaston confirmed him as army commander . But his doom was sealed when he was arrested by order of Representatives Édouard Milhaud and Pierre Soubrany on 10 January 1794 . He was also denounced by his jealous rivals , Turreau and Doppet . Accused of malice and disability , d ' Aoust was sentenced to death by the Revolutionary Court . He was guillotined in Paris on 2 July 1794 at the age of 31 years .
