Siege of Santiago Siege of Santiago The Siege of Santiago also known as the Siege of Santiago de Cuba was the last major operation of the Spanish–American War on the island of Cuba. This action should not be confused with the naval battle of Santiago de Cuba. The primary objective of the American Fifth Army Corps' invasion of Cuba was the capture of the city of Santiago de Cuba. U.S. forces had driven back the Spaniards' first line of defense at the Battle of Las Guasimas, after which General Arsenio Linares pulled his troops back to the main line of defense against Santiago
Battle of Santiago de Cuba prisoners were returned to Spain with their “honors of war” on American ships. The battle was the end of any noteworthy Spanish naval presence in the New World. It forced Spain to re-assess its strategy in Cuba and resulted in an ever-tightening blockade of the island. While fighting continued until August, when the Treaty of Paris was signed, all surviving Spanish capital ships were now husbanded to defend their homeland leaving only isolated units of auxiliary vessels to defend the coast. Uncontested U.S. control of the seas around Cuba made resupply of the Spanish garrison impossible and its surrender inevitable.
