The French invaded Andalusia on 19 January 1810. 60,000 French troops—the corps of Victor, Mortier and Sebastiani together with other formations—advanced southwards to assault the Spanish positions. Overwhelmed at every point, Aréizaga's men fled eastwards and southwards, leaving town after town to fall into the hands of the enemy. The result was revolution. On 23 January the Junta Central decided to flee to the safety of Cádiz. It then dissolved itself on 29 January 1810 and set up a five-person Regency Council of Spain and the Indies, charged with convening the Cortes. Soult cleared all of southern Spain except Cádiz, which he left Victor to blockade. The system of juntas was replaced by a regency and the Cortes of Cádiz, which established a permanent government under the Constitution of 1812.
