in the midst of this political bickering, colonel enrique campino, with the support of the radical federalist group, organized a military coup with the santiago garrison, dissolving congress and imprisoning some conservative ministers, chief among them diego portales and manuel josé gandarillas. finally the government managed to control the situation and imprison colonel campino, but president eyzaguirre had had enough. on january 25, 1827, he presented his resignation to congress, which accepted it, and proceeded to name ramón freire as presidente and francisco antonio pinto as vice president of chile.
