Pierre Deval and other French residents of Algiers left for France, while the Minister of War, Clermont-Tonnerre, proposed a military expedition. However, the Count of Villèle, an ultra-royalist, President of the council and the monarch's heir, opposed any military action. The Bourbon Restoration government finally decided to blockade Algiers for three years. Meanwhile, the Berber pirates were able to exploit the geography of the coast with ease. Before the failure of the blockade, the Restoration decided on 31 January 1830 to engage a military expedition against Algiers.
