The siege of Alès was undertaken by Louis XIII of France, and the city captured on 17 June 1629.

Huguenot resistance persisted in the south of France though, and Louis XIII endeavoured to eliminate it as well.

[1] With Privas and Anduze, the city of Alès was at the center of a string of Protestants strongholds in the Languedoc, stretching from Nîmes and Uzès in the east, to Castres and Montauban in the west.

[2] Alès was selected by Antoine Hercule de Budos, Marquis des Portes (1589-1629), as a strategic target to sever Huguenot defenses in two and disconnect their main centers of Nîmes and Montauban.

[2] After Privas fell on 28 May 1629, in which the Marquis des Portes was killed, French attention turned to Alès.
