This military map of Puerto Rico was published in 1898, the year in which the United States, in the course of the Spanish-American War, seized the island from Spain. Hostilities began on May 12 with a blockade and bombardment of the city of San Juan by the U.S. Navy. This was followed with the landing off the coast of Guánica on July 12 of a force of 1,300 U.S. soldiers. In the peace treaty that was signed in Paris on December 10, 1898, the United States formally acquired Puerto Rico from Spain, along with Guam and the Philippines. Issued by the Military Information Division of the Adjutant General's Office of the U.S. Army, the map is by W. Morey of the U.S. Army Corps of Engineers. The emphasis is on transportation, with railroads, main roads, cart trails, and horse trails shown. The scale is in miles (1 mile = 1.61 kilometers). An inset map at the lower right shows Vieques, Culebra, and several smaller islands belonging to Puerto Rico
