Carlist forces land in Catalonia and declare the pretender Don Carlos as rightful King of Spain

A Carlist uprising in Spain began with the landing of rebel General Ortega and the Carlist pretender, Carlos, Count Montemolin, together with his brother Ferdinand, on the northern coast of Catalonia.  At Tortosa, Ortega declared Montemolin as King Don Carlos I.  The rising ended soon after when Ortega's troops proclaimed themselves loyal to sitting Queen Isabella and arrested their general and the two royal claimants.  Ortega was shot for treason on April 19, 1860.  (By John Osborne)
