The assault resulted in the deaths of Joana Angélica and Daniel da Silva Lisboa.
On February 18, a group of independence supporters, including soldiers, officers, and civilians, occupied the Fort of São Pedro in Salvador.
In response, Madeira de Melo ordered the fort to be bombarded, forcing the rebels to abandon their position and retreat into the countryside.
The convent, a place of sanctuary for nuns, became the focus of their aggression as the invaders sought to break its isolation.
Joana Angélica was fatally wounded by bayonet strikes as she tried to protect the nuns, alongside father Daniel da Silva Lisboa, who was beaten to death.
