Gazan de la Peyriére (1765-1845) was a French general who fought under Napoleon.

Honoré Theodore Maxime Gazan de la Peyriére was born in a small town of Grasse, France on October 29 1765. His lawyer father sent him to College of Soreze where he received military training and eventually joined the French Royal Life Guards in 1786. Afterwards he also joined the Freemasons.

Upon the eruption of the French Revolution, Gazan returned to Grasse and joined the national guard. In 1790 he had become a captain and in 1971 a lieutenant colonel of the local volunteer battalion of Var. In 1972 he was sent to the 27th regiment as a captain and took the regiment to the [[Rhine]9 upon the declaration of war with Austria. Regiment first became a garrison troops in [[Strasbourg]9 but joined the battle in December near Weissenbourgh.

In May 1794 Gazan became a battalion commander of a new 54th demi-brigade but was promoted to brigade colonel in July 11. He lead his troops to victory against Prussians in Trippstadt.

In 1796 he took part of many battles in southern Germany. In July 4 he routed the enemy in Kuppenheim by ordering his drummers to beat a charge which fooled Prussians to think they were facing superior odds. Gazan was wounded November 22 1796 and taken to Strasbourg where he married Marie Madeleine Reiss. He would often take his wife to his campaigns.

In April 4 1799 Gazan was promoted to brigade commander and his superior and friend André Masséna transferred him to the Army of Danube where he faced Austrian and Russian forces. On September 27 Gazan repulsed Russian outposts in at the Limmat river and pursued the enemy to the defenses of Zürich. He was promoted to division commander and continued a campaign against Allied troops in Switzerland.

When Napoleon declared himself the first consul, he assigned Masséna and Gazan to hold the fortress in Genoa. Gazan arrived to Italy in March 1800 and fought in the Austrian siege of Genoa until Masséna capitulated in June 4. Gazan, who had been wounded to the head in May 2, took his troops to Lozano and joined general Suchet. He was put into the command of division in the Army of Italy and fought in a victorious battle in Pozzolo against Austrians in December 25.

Gazan returned to home but soon received new assignment as a commander of a sub-division in northern Italy where he stayed until the declaration of the Empire in 1804. In 1805 he was assigned as a division commander of Napoleon's Grande Armee in Lille in preparation of the invasion of England until the idea was abandoned.

In August 1805 Gazan found himself in command of a division that encircled Austrians in Ulm. On November 11 his division was the advance guard in the march against Kutuzov's army under marshal Mortier and was isolated. Gazan fought desperately and lost 40% of his troops until he was relieved by evening. He received the Officer's Grand Cross and his division was sent to Vienna to recuperate. When Austria sued for peace, Gazan's division was sent to Wurstburg in Bavaria where they remained until Prussia declared war again in October 1806.

Gazan's division fought in Cosped in October 14. On Ostrolenka in February 16 Gazan's troops took three guns and Russian colours. Otherwise his troops stayed in their quarters. After the new peace treaty, Gazan's troops were sent to Silesia where they ended up mistreating the local population. Gazan was invited to restore order and he was created Count de la Peyriére.

In October 1808 Gazan's 5th Corps went to Spain with Lannes and arrived in Saragossa in December. Saragossa was under siege and defended by Spanish under José Palafox. Gazan's general Lannes ordered offensive in January 22 1809 and Gazan's troops joined the effort to capture the city street by street. Palafox surrendered in February 20. 5th corps occupied northern Aragon.

In November, Gazan was sent to invade Andalusia and set to guard Estremadura valley in July. In September he fought against Spanish general [[La Romana]9. In January 1811 he crossed the Sierra Morena to support Marshal Soult in siege of Badajoz to guard supply lines. In January 25 he defeated Spanish general Ballesteros in Villanueva de los Castillejos. He also fought in Malbuera in May 16 1811. He was wounded and returned to Seville as a chief of staff. In February 1813 Gazan replaced Soult as a commander of the army of the South.

After the major offensive by the Duke of Wellington, Gazan's Army of the South held the first line on the heighs of Puebla. On June 21 General Hill and Morillo attacked him and he decided to withdraw and abandon all artillery. His movement created a gap in French line which lead to loss of 4000 men. Retreat turned into a rout. Allies captured the supply convoy and took many prisoners, including Gazan's wife and children who later managed to rejoin him.

When Soult took command of the new Army of the Pyrenees, Gazan became the chief of staff until Napoleon's abdication.

During the Hundred Days, Gazan hesitated but eventually joined Napoleon. He did not receive field command. Louis XVIII forced him to retirement in Grasse where he unsuccessfully dabbled in politics. After 1840 revolution, he was made a peer and received a command of military division in Marseilles. He retired in June 1832 due to ill health.

Gazan de la Peyriére died in Grasse in April 9 1845.
