Anne-François-Charles Trelliard or Treillard or Treilhard (7 February 1764 – 14 May 1832), joined the cavalry of the French Royal Army as a cadet gentleman in 1780.

In April 1793, he advanced to the rank of chef d'escadron (major) in the 11th Chasseurs after fighting in the Army of the North and other formations.

[1] Historian Charles Mullié credits Trelliard with serving under Jean Victor Marie Moreau in the blockade of Mainz.

However, another source places the 11th Chasseurs in François Séverin Marceau-Desgraviers' Division, which was involved in the futile blockade of Ehrenbreitstein Fortress from 15 September to 17 October.

[1] Trelliard led the light cavalry of Marshal Jean Lannes' V Corps at the beginning of the War of the Third Coalition.

[6] Commanding nine squadrons of the 9th and 10th Hussars and the 21st Chasseurs at the outbreak of the War of the Fourth Coalition,[7] Trelliard fought at the Battle of Saalfeld on 10 October 1806.

[12] Though he was not listed in the official Army of Portugal order of battle, which placed Louis Pierre, Count Montbrun in charge of the reserve cavalry,[13] staff officer Jean-Jacques Germain Pelet-Clozeau stated that he led a cavalry division during the Siege of Almeida under Marshal André Masséna's personal command.

[14] After the Battle of Bussaco, Masséna ordered Montbrun to take command of the army's advance guard while Trelliard assumed direction of the reserve cavalry.

[18] As the French withdrew from Portugal, he assisted Marshal Michel Ney's rear guard with three dragoon regiments on 10 March, the day before the Battle of Pombal.

Coming under fire from the KGL infantry in the village of Las Rozas and seeing reinforcements approaching, Trelliard ordered a withdrawal and abandoned his captured guns.

[20] On 21 June 1813 at the Battle of Vitoria, Trelliard commanded the 1,038 horsemen in his four French dragoon regiments as part of the Army of the Center.

[23] After Marshal Nicolas Soult reorganized the army in the late summer of 1813, he led a 2,358-strong cavalry division consisting of six regiments.

[25] At the Battle of the Nive on 10 December 1813, Louis-Ernest-Joseph Sparre's dragoon brigade of his division overran the 1st Portuguese Line Infantry Regiment.

[28] On 23 and 24 February there was a clash at Troyes where the 21st and 26th Dragoons of Auguste Jean Joseph Gilbert Amiel's cavalry brigade defeated 3,600 Austrians.

[31] All six regiments that served under Trelliard in July 1813 are listed as being in Nicolas François Roussel d'Hurbal's 6th Dragoon Division on 30 March at the Battle of Paris.
