Answer:
The correct answer is 2. It is false that Cuban rebels did most of the fighting even after the Americans joined in the war.
Step-by-step explanation:
In January 1898, violent clashes in Havana led the battleship USS "Maine" to be ordered to Havana's port to protect American citizens. On February 15, 1898, the ship was shaken by a powerful explosion while it was docked. A total of 266 of the crew of 400 men lost their lives. On April 23, McKinley asked for 125,000 volunteers and the day after Spain declared war on the United States. The American Declaration of War was adopted by Congress on April 25, 1898.
On May 1, 1898, the Spanish Pacific fleet was defeated by an American naval force under the command of Admiral George Dewey of Manila Bay in the Philippines. This victory opened to US occupation of Manila in August. In Cuba, a Spanish naval force sailed into the port of Santiago in May after a swift voyage across the Atlantic, but a significantly stronger US naval force arrived shortly after, blocking entry to the port. In June, the U.S. 5th Army Corps landed and the plan was for this force, together with the fleet, to conduct a coordinated attack on Santiago.
On July 1, 1898, the Americans won the Battle of San Juan Hill and the day after the siege of Santiago began. On July 3, the Spanish Navy was defeated outside Santiago by the US Navy under the command of Admiral William Sampson. On July 17, the Spanish forces capitulated in Santiago - and thus also in the rest of Cuba. The Spanish resistance in Puerto Rico crumbled and on August 12, a ceasefire agreement was signed between the United States and Spain.
As it can be noted, the most outstanding actions of the war were carried out by American forces. In fact, about 300,000 Americans were involved in the war, while only 30,000 rebels did it on the Cuban side.
