He spent the fifteen years after the fall of Napoleon without employment, returning to agriculture and developing his home district of Périgord. The
July Revolution of 1830 reopened his military career, and after a short tenure of regimental command he was in 1831 promoted brigadier-general (
maréchal de camp). In the same year, he was elected to the French parliament's lower house, the
Chamber of Deputies, where he showed himself to be an inflexible opponent of
democracy. In his military capacity, he was noted for his severity in suppressing riots. His conduct as gaoler of the
Duchess of Berry led to a duel in 1834 between Bugeaud and the deputy in which the latter was killed; this affair, and the heavy-handed suppression of a further riot, exposed Bugeaud to ceaseless attacks in the Chamber and in the press, though his opinion was sought by all parties in matters connected with agriculture and industrial development. He was re-elected in 1834, 1837, and 1839.
Algeria Although he initially disapproved of the conquest of Algeria, his undeviating adherence to
Louis Philippe brought him into agreement with the government. He embarked on a campaign to win the swift, complete, and lasting subjugation of Algeria. He was sent to
Africa with orders from Paris to bring the war in western Algeria to a satisfactory conclusion, wherein he proceeded to initiate his war of
flying columns. He won his first victory on the 6th of July 1836 in the
Battle of Sikkak against an army of 10,000 regular and tribal warriors of Abd al-Qadir, and returned home with the rank of lieutenant-general. In the following year, he signed the
Treaty of Tafna (30 May 1837), with
Abd al-Qadir, which led to attacks upon him in the
chamber, to the refutation of which Bugeaud devoted himself in 1839. There is also controversy about the language Bugeaud inserted into the differing versions of the treaty, in French article one read that Abd al-Qadir ‘recognised the sovereignty of France in Africa’. The Arabic text instead read that "the amir ‘is aware of the rule of French power" (ya‘rifu hukm saltanat firansa) in Africa’. McDougall argues on the basis of Abd al-Qadir's letters to Bugeaud negotiating the treaty that it cannot have been a translation error and the differing meaning of the texts constitutes duplicity on Bugeaud's part. His swiftness and energy drove back the forces of Abd al-Qadir from place to place, while the devotion of the
rank and file to "Père Bugeaud" enabled him to carry all before him in action. In 1842, he secured the French positions by undertaking the construction of roads. In 1843, Bugeaud was made
marshal of France, and in this and the following year he continued his operations with unvarying success. His great victory of
Isly on 14 August 1844 defeated a Moroccan army that attempted to intervene in Algeria so decisively that effectively a civil war broke out between the Moroccans and Abd al-Qadir and won him the title of
duke. In 1845, however, he had to take the field again in consequence of the disaster of
Sidi Brahim (22 September 1845), and up to his final retirement from Algeria (July 1846) he was almost constantly employed in the field, by ordering in February 1846 to General
Jean-François Gentil to organize the second campaign against the rebels of
Kabylia. His resignation was due to differences with the home government on the question of the future government of the province. Amidst his other activities he had found time to study the agricultural characteristics of the conquered country, and under his régime the number of French colonists had grown from 17,000 to 100,000. == Counter insurgency strategy in Algeria and his legacy in military strategy ==
