Puerto Cabezas
Shortly after Sandino returned to Nicaragua, the Constitutionalist War began when Liberal soldiers in the Caribbean port of Puerto Cabezas revolted against the Conservative President Adolfo Díaz, who had recently been installed after a coup with United States involvement. The leader of this revolt, General José María Moncada, declared that he supported the claim of the exiled Liberal vice-president Juan Bautista Sacasa.
