The Battle of Puebla (May5, 1862) - Level 3

 



 How Did France End Up in Mexico?

Let’s rewind a bit. In the 1850s and early 1860s, Mexico was broke. After years of internal conflict (like the Reform War between liberals and conservatives), the Mexican economy was so dead it would’ve bounced a check for a taco.

In 1861, Mexican President Benito Juárez made a practical but controversial decision: he suspended all foreign debt payments for two years.
Europe? Not thrilled.

So in late 1861, France, Britain, and Spain got together like a colonial Avengers squad and decided to send troops to Mexico to “encourage” repayment.

But after a bit of negotiating, Britain and Spain peaced out, realizing Juárez wasn’t being a jerk—he was just genuinely broke.
France, though? France had other ideas.
Their emperor, Napoleon III (the discount sequel to Napoleon Bonaparte), saw this as a golden opportunity to flex some imperial muscle and establish a French-controlled empire in Latin America. (He also thought the U.S. would be too busy with its Civil War to interfere. Spoiler: He was right — for a while.)


Enter the Battle of Puebla – May 5, 1862

In early 1862, a French expeditionary force landed in Veracruz and began marching inland. Their goal: take Mexico City, install a puppet emperor, and turn Mexico into Napoleon III’s personal French Disneyland.

By the time they reached the fortified city of Puebla, French troops numbered around 6,000, led by General Charles de Lorencez — a man reportedly so confident in victory, he may as well have packed wine and cheese for a picnic.

Waiting for them was Mexican General Ignacio Zaragoza, with about 4,500 troops, most of them under-equipped, under-trained, and probably wondering why the heck they were facing off against one of the most powerful armies in Europe.

Zaragoza famously told his men:

“They may be the first army in the world, but we are the first sons of Mexico.” 🇲🇽

So on the morning of May 5, 1862, the French attacked the Forts of Loreto and Guadalupe, positioned on high ground above the city. Lorencez assumed that, with superior numbers and tech, it would be a quick job.
But nature had other plans.

It rained. The battlefield turned into a muddy mess. French cavalry floundered. Their cannons sank. Their boots probably squished.

And the Mexican defenders? They used the terrain masterfully. They fought tooth-and-nail, held the high ground, and inflicted heavy casualties.

After three frontal assaults, with nearly 500 French troops dead, Lorencez finally gave up and retreated — humiliated by what was supposed to be a routine mop-up operation.

Mexican losses? Fewer than 100.

Why It Mattered (Even Though It Wasn’t the End)

In military terms, the Battle of Puebla wasn’t a decisive strategic victory. The French would regroup and eventually take Mexico City in June 1863, forcing Juárez’s government into exile.

But Puebla mattered. Immensely. Here’s why:

  • It shattered the myth of European invincibility in Latin America.

  • It boosted Mexican morale at a time when the country desperately needed hope.

  • It delayed the French advance, buying the Republic time.

  • And it showed that Napoleon III’s imperial dream wasn’t going to go unchallenged.

And it also gave us the line that belongs in a movie trailer:

“We beat the most powerful army in the world—with old rifles, dirt roads, and zero chill.”


So Why Do We Celebrate Cinco de Mayo?

Contrary to popular belief (especially in the U.S.), Cinco de Mayo is not Mexican Independence Day (that’s September 16, 1810).

Cinco de Mayo commemorates the Battle of Puebla — a moment when a ragtag Mexican force embarrassed a European superpower. It represents resistance, national pride, and punching above your weight class.

Ironically, the day is more widely celebrated in the United States than in most of Mexico — largely thanks to Chicano activists in the 1960s and, later, a lot of beer companies looking for a reason to sell more alcohol in May. 

Still, it stands as a symbol: You don’t need to have the biggest army to win the most important fight. Sometimes, grit > guns.


 

After the Battle: Victory... Then the Real Trouble Begins

So, it’s May 5, 1862.
General Zaragoza and his underdog troops just served the French a steamy plate of “Nope.”

The French army, battered and embarrassed, retreats. Mexico celebrates. President Benito Juárez is thrilled.
And Zaragoza becomes a national hero overnight (though tragically, he dies of typhoid a few months later, in September 1862 — RIP to a real one ).

But let’s be clear: this was a battle won, not a war ended.


France: The Empire Strikes Back

Napoleon III, sitting in Paris, gets the news and basically goes:

“Excuse me? My imperial army got beat by a bunch of poorly equipped republicans in Mexico? …No. Run that back.”

He sends massive reinforcements — around 30,000 troops, along with better gear, supplies, and generals who hopefully read the terrain manual this time.

By May 1863, the French army returns to Puebla, lays siege, and this time? They win.
Not exactly a fair rematch when you bring five times the soldiers and siege artillery, but hey, imperialism rarely plays fair.

A month later, in June 1863, the French march into Mexico City. Benito Juárez and the Mexican republican government flee north and go into resistance mode.


And Now… a European Emperor in Mexico

Napoleon III wasn’t just trying to collect debts anymore — this had turned into a full-blown imperial vanity project.
So, in 1864, he recruits Archduke Maximilian of Austria, a well-meaning but painfully naive Habsburg, to rule as Emperor of Mexico.

Yes, a European royal was plopped into the middle of Mexico and told:

“Here’s your throne. Rule these people who didn’t ask for you. Good luck!” 

Maximilian actually had some progressive ideas—he supported land reform, opposed the death penalty, and tried to work with liberals—but... yeah. He was literally the figurehead of a foreign invasion. Awkward.

Meanwhile, Juárez was in the north going full resistance-mode: reorganizing loyalist forces, conducting a guerrilla campaign, and refusing to recognize Maximilian’s legitimacy.


The U.S. Finishes Its Civil War — And Looks South

Now here’s the plot twist Napoleon III didn’t anticipate:
By 1865, the American Civil War was over, and the U.S. was not happy that a European empire was squatting in their hemisphere, violating the Monroe Doctrine (which basically said “No European empires in the Americas, please and thank you”).

The U.S. government:

  • Recognized Benito Juárez as the legitimate president

  • Sent diplomatic pressure to France

  • Stationed troops at the U.S.–Mexico border

  • Made it very clear that Napoleon III was playing a very dangerous game

Napoleon, realizing he’d overextended, was hemorrhaging cash, and had zero stomach for war with the U.S., began pulling troops out of Mexico.

By early 1867, the French were gone.
Maximilian, tragically oblivious or stubborn (or both), refused to leave with them.


Game Over for Maximilian

Maximilian believed he still had support. He didn’t.
Republican forces, under General Porfirio Díaz (yes, that Porfirio Díaz), closed in.

Maximilian was captured in Querétaro, tried for treason, and sentenced to death.

On June 19, 1867, he was executed by firing squad — along with his top generals. (Despite pleas for mercy from Queen Victoria, Napoleon III’s wife, and Victor Hugo. Yes, that Victor Hugo.)

The Empire was dead.
Juárez returned to Mexico City.
The Mexican Republic was restored.


The Aftermath: Mexico, Shaken But Not Broken

  • Juárez resumed the presidency and set about rebuilding.

  • The war had devastated the country—economically, politically, and socially—but it had also solidified national identity.

  • The victory at Puebla (and later, the resistance victory in 1867) became legendary.


So What’s the Takeaway?

  • The Battle of Puebla wasn’t the end — it was the opening act of a much bigger war over Mexico’s sovereignty.

  • But it mattered, deeply. It bought time. It gave the people a symbol. It proved that even against imperial giants, a determined republic could hold the line.

  • And in the long run? The empire fell. The republic stood. Benito Juárez got the last word.
