Battle of Guantánamo Bay Battle of Guantánamo Bay The Battle of Guantánamo Bay was fought from June 6 to June 10 in 1898, during the Spanish–American War, when American and Cuban forces seized the strategically and commercially important harbor of Guantánamo Bay, Cuba. Capturing the bay from the Spanish forces was instrumental in the following Battle of Santiago de Cuba and the subsequent invasion of Puerto Rico. Although overshadowed by the land and sea battles at Santiago, the establishment of the United States naval base at Guantánamo Bay and the rout of defending Spanish troops by American and Cuban forces was important in the
Siege of Santiago along San Juan Heights. In the charge at the Battle of San Juan Hill U.S. forces captured the Spanish position. At the Battle of El Caney the same day, U.S. forces took the fortified Spanish position and were then able to extend the U.S. flank on San Juan Hill. The destruction of the Spanish fleet at the Battle of Santiago de Cuba allowed U.S. forces to safely besiege the city. On July 3, 1898, the same day as the naval battle, Major General William "Pecos Bill" Shafter began the siege of Santiago. Shafter fortified his position on San Juan Heights.
