The Second Battle of Las Cruces, or the New Year's Day Battle, was a major engagement during the American occupation of Nicaragua. It was fought on 1 January 1928, during an expedition to destroy a Sandinista fortress. A column of United States Marines and Nicaraguan National Guardsmen were attacked by a superior force of rebels entrenched on Las Cruises Hill and, after a long battle, the Americans and Nicaraguans routed the Sandinistas and captured their positions.
