The year was 1898. Most Americans at the time probably couldn't have pointed to Manila on a map if their lives depended on it. Yet, within a matter of months, the United States was effectively a global empire, having dismantled what was left of the Spanish Crown's once-mighty holdings. When people ask where was the Spanish American War fought, they usually think of Teddy Roosevelt charging up San Juan Hill in Cuba. That's the textbook answer. It's also only about half the story.
This wasn't just a Caribbean scuffle. It was a messy, humid, multi-oceanic explosion of violence that stretched from the tropical jungles of Southeast Asia to the white sands of Puerto Rico.
The Caribbean Theater: More Than Just Cuba
Honestly, Cuba was the main event. It had been simmering for years before the USS Maine blew up in Havana Harbor. But even within Cuba, the geography of the war was specific. Most of the heavy lifting happened on the eastern end of the island, near Santiago de Cuba.
The U.S. Navy basically blockaded the northern coast, trying to starve out the Spanish forces. However, the ground war was a chaotic mess of volunteer regiments—like the famous Rough Riders—and Buffalo Soldiers. They landed at Daiquirí and Siboney, pushing through thick brush and dealing with yellow fever, which, frankly, killed more men than Spanish Mauser bullets did.
San Juan Hill and El Caney
You've heard of San Juan Hill. But the Battle of El Caney happened simultaneously on July 1, 1898. While Roosevelt’s crew was taking the heights, another force was struggling to capture a small stone fort nearby. It took way longer than expected. The Spanish were dug in deep. They were outnumbered, sure, but they had better smokeless powder.
The Invasion of Puerto Rico
While everyone focuses on Cuba, we can't ignore Puerto Rico. In late July, General Nelson A. Miles landed at Guánica. It wasn't nearly as bloody as the Cuban campaign. The Americans moved across the island toward San Juan, but the war ended before they could take the capital. Most Puerto Ricans at the time actually welcomed the Americans, hoping for an end to Spanish colonial rule, though the long-term political fallout is something scholars like Nelson Denis still write about today.
The Pacific Theater: A Surprise in the Philippines
If you want to know where was the Spanish American War fought, you have to look 8,000 miles away from Washington D.C.

Commodore George Dewey was in Hong Kong when he got the order: "Find the Spanish fleet and destroy it." He sailed into Manila Bay under the cover of darkness. By noon on May 1, 1898, the Spanish Pacific squadron was essentially driftwood.
- Manila Bay: The naval battle that changed everything.
- Cavite: Where the U.S. set up its initial base of operations.
- The Walled City (Intramuros): This is where the Spanish surrendered, but only after a "mock battle." They didn't want to surrender to the Filipino revolutionaries; they wanted to lose to the "civilized" Americans. It was a weird, choreographed face-saving maneuver.
The Siege of Baler
This is one of those wild historical footnotes. A small group of Spanish soldiers held out in a church in Baler for 337 days. They didn't believe the war was over. They thought the newspapers reporting the Spanish defeat were fake news. Talk about commitment.
The Forgotten Conquest of Guam
Then there's Guam. This is almost comical in a dark way. The USS Charleston sailed into Apra Harbor and fired a few shells. The Spanish commander, who hadn't received mail in months, actually sent an officer out to the American ship to apologize for not returning the "salute."
He didn't even know Spain and the U.S. were at war.
He had no gunpowder. He had no choice but to surrender the entire island. Just like that, the U.S. had a stepping stone to Asia. It took less than a day. No casualties.
Why the "Where" Matters So Much
The locations of these battles weren't random. They were the nodes of a dying empire. Spain was holding onto the remnants of a 15th-century vision, while the U.S. was looking for 20th-century coaling stations for its New Steel Navy.

Historians like Louis A. Pérez Jr. argue that the war was less about "liberating" these places and more about controlling the gateways to global trade. If you control Manila, you have a window into China. If you control Puerto Rico and Cuba, you control the approaches to the future Panama Canal.
The Impact on the Ground
- Disease: Malaria and Yellow Fever were the true "combatants" in the Caribbean.
- Infrastructure: The U.S. built roads and telegraph lines in these occupied territories almost immediately.
- Resistance: In the Philippines, the war didn't end in 1898. It just turned into the Philippine-American War, a much longer and bloodier conflict that many people conveniently forget.
The Logistics of a Two-Ocean War
Think about the sheer nightmare of moving troops in 1898. There was no Panama Canal yet. To get ships from the Atlantic to the Pacific, you had to go all the way around Cape Horn at the bottom of South America. The USS Oregon had to do this, and the 66-day journey convinced the American public that they absolutely needed a canal.
The U.S. Army was woefully unprepared for the climate of the places where the war was fought. Soldiers were issued heavy wool uniforms—standard issue for fighting on the Great Plains—and sent to the sweltering heat of Santiago. They were eating "embalmed beef" that made everyone sick. It was a logistical train wreck that somehow resulted in a total victory.
Naval Dominance
The war was ultimately won at sea. Without the victories at Manila Bay and Santiago Harbor, the land battles wouldn't have mattered. The Spanish fleet was antiquated. Their wooden ships were death traps against American steel.
Global Consequences of the Geographic Spread
Because the war was fought in both the Atlantic and the Pacific, the United States became a "two-ocean" power overnight. This shifted the entire global balance of power. Germany and Japan started looking at the U.S. differently. They realized the Americans weren't just isolationists anymore.
When the Treaty of Paris was signed in December 1898, Spain ceded Puerto Rico, Guam, and the Philippines to the U.S. (the Philippines cost $20 million). Cuba became a protectorate. Basically, the map of the world was redrawn in a single year.

Actionable Insights for History Buffs
If you’re researching the Spanish American War, don't just look at the American perspective. Check out the Archivo General de Indias in Seville if you ever get the chance (they have digital records too).
Key places to visit today for a real sense of the history:
- Castillo San Felipe del Morro (Puerto Rico): You can still see where American shells hit the lighthouse.
- San Juan Hill (Cuba): Now a memorial park, though it can be tricky for Americans to visit depending on current travel restrictions.
- The National Museum of the Philippines (Manila): Essential for understanding the revolutionary side of the conflict.
To really grasp the scope, look at the "Log of the USS Oregon." It tracks the incredible journey from San Francisco to Florida, illustrating the geographic hurdles of the era. Understanding the "where" tells you the "why." This wasn't just a war for independence; it was a war for position.
If you want to dive deeper into the gritty details of the soldiers' lives, read The Martial Spirit by Walter Millis. It’s an older text, but it captures the chaotic, almost accidental way the U.S. stumbled into these various theaters of war.
The Spanish-American War proved that geography is destiny. By fighting in the Caribbean and the Pacific simultaneously, the United States ensured it would spend the next century as the dominant force in both hemispheres. It was a brief conflict—lasting only about ten weeks of actual fighting—but its footprint remains visible on the map of American territories today.
