Who achieved a significant victory over the Spanish fleet in 1898?

The significant victory over the Spanish fleet in 1898 was achieved by George Dewey during the Spanish-American War. On May 1, 1898, Dewey led a surprise attack against the Spanish fleet in Manila Bay, Philippines. His strategic naval tactics and the modern capabilities of his ships played a critical role in defeating the Spanish forces, leading to the eventual capture of Manila.

This victory was pivotal for the United States, marking its emergence as a global naval power and significantly weakening Spanish influence in the region. Dewey's triumph is often celebrated for its speed and decisiveness, as his fleet suffered no casualties while the Spanish lost many of their ships.

The other figures listed do not pertain to this conflict: John of Austria was known for his role in earlier European battles against the Ottomans in the 16th century, Sam Houston is famous for his leadership in the Texas Revolution, and Ramses II was a prominent pharaoh of ancient Egypt, far removed from the context of the Spanish-American War.
