The mounting pressure forced Cánovas to replace General Campos with General Valeriano Weyler, a soldier who had experience in quelling rebellions in overseas provinces and the Spanish metropole. Weyler deprived the insurgency of weaponry, supplies, and assistance by ordering the residents of some Cuban districts to move to reconcentration areas near the military headquarters. This strategy was effective in slowing the spread of rebellion. In the United States, this fueled the fire of anti-Spanish propaganda. In a political speech President William McKinley used this to ram Spanish actions against armed rebels. He even said this "was not civilized warfare" but "extermination".
