The Puerto Rican Campaign was an American military sea and land operation on the island of Puerto Rico during the Spanish–American War. The offensive began on May 12, 1898, when the United States Navy attacked the archipelago's capital, San Juan. Though the damage inflicted on the city was minimal, the Americans were able to establish a blockade in the city's harbor, San Juan Bay. On June 22, the cruiser Isabel II and the destroyer Terror delivered a Spanish counterattack, but were unable to break the blockade and the Terror was damaged.

The land offensive began on July 25, when 1,300 infantry soldiers led by Major General Nelson A. Miles disembarked off the coast of Guánica. After controlling the first skirmish, the Americans advanced to Coamo, where they engaged Puerto Rican and Spanish troops in battle. The battle concluded when the allied soldiers retreated after the battle left two dead on their side, and four on the American side. The United States was able to seize control of Fajardo on August 1, but were forced to withdraw on August 5 after a group of 200 Puerto Rican-Spanish soldiers led by Pedro del Pino gained control of the city, while most civilian inhabitants fled to a nearby lighthouse. The Americans encountered larger opposition as they advanced towards the main island's interior. They engaged in two crossfires in Guamani River and Coamo, both of which were inconclusive as the allied soldiers retreated. A battle in San Germán concluded in a similar fashion with the Spanish retreating to Lares.
