Пуэрто-Кабесас
Civil war erupted between the conservative and liberal factions on May 2, 1926, with liberals capturing Bluefields, and José María Moncada Tapia capturing Puerto Cabezas in August. Juan Bautista Sacasa declared himself Constitutional President of Nicaragua from Puerto Cabezas on December 1, 1926. Following Emiliano Chamorro Vargas' resignation, the Nicaraguan Congress selected Adolfo Diaz as "designado", who then requested intervention from President Calvin Coolidge. On January 24, 1927, the first elements of US forces arrived, with 400 marines.
