On July 25, 1898, lighthouse keeper Robustiano Rivera spotted the convoy of the American forces that initiated the landing offensive of the Puerto Rican Campaign during the Spanish–American War. He immediately gave the alert to the residents of Guánica and marched to Yauco where he broke the news of the invading forces to the city's mayor.[4][5]
