The destruction of Panama so soon after the signing of the treaty led to what Allen describes as "a crisis in international affairs" between England and Spain. The English government heard rumours from their ambassadors in Europe that the Spanish were considering war. In an attempt to appease them, Charles II and his Secretary of State, the Earl of Arlington, ordered Morgan's arrest. In April 1672 the privateer admiral was returned to London where, Barbour writes, he was "handsomely lionized ... as the hero on whom Drake's mantle had fallen". Although some sources state that Morgan was also incarcerated in the Tower of London, Pope writes that Tower records make no mention of his presence there.
