Explanation:

During the lead-up and declaration of the Spanish-American War, there was widespread patriotic fervor in the U.S. This led to a surge in men volunteering for military service, including the famous Rough Riders regiment. Fears of Spanish conquest of Florida were unfounded, large anti-war demonstrations were not the dominant response, and while some had concerns about military preparedness, mass volunteering was the most prominent reaction.

Many men volunteered for military service.
