Union Blockade: Prize Money, British Runners and Egypt's Cotton Bankruptcy

SPEAKER_1 (0:00)

So, it's April 1861, and Abraham Lincoln issues this proclamation that, strictly on paper, sounds completely impossible.

SPEAKER_2 (0:08)

Oh, absolutely impossible.

SPEAKER_1 (0:10)

Right. He declares a naval blockade covering, like, 3,500 miles of Confederate coastline, which is just geographical audacity.

SPEAKER_2 (0:20)

Yeah, it's a massive, massive area.

SPEAKER_1 (0:23)

But underneath the logistics of it, there's this really massive legal paradox, you know, because under international law, the government cannot legally blockade its own ports.

SPEAKER_2 (0:33)

Right, because a blockade is recognized as an act of war between two sovereign nations.

SPEAKER_1 (0:37)

Exactly. So by declaring a formal blockade, Lincoln is, uh, he's inadvertently flirting with recognizing the Confederacy as a legitimate, independent, belligerent nation, rather than just, you know, putting down a domestic insurrection.

SPEAKER_2 (0:51)

Yeah, it's a huge geopolitical risk.

SPEAKER_1 (0:54)

And the craziest part is, at the exact moment he signs this order, the United States Navy only possesses three ships actually capable of doing the job. Three.

SPEAKER_2 (1:04)

It is, uh, basically the ultimate definition of writing a check your military bank account cannot possibly cash.

SPEAKER_1 (1:10)

Right.

SPEAKER_2 (1:11)

I mean, you're looking at a mandate to seal off a massive jagged chunk of a continent. It's got hundreds of inlets, bays, barrier islands. And your enforcement mechanism to choke off a whole nation's economy is effectively three boats.

SPEAKER_1 (1:25)

Well, welcome to today's Deep Dive. We are exploring the Union blockade of the American Civil War.

SPEAKER_2 (1:31)

It's a wild story.

SPEAKER_1 (1:32)

It really is. And our mission for you today is to unpack how the United States somehow pulled off the largest blockade ever attempted up to that point in history.

SPEAKER_2 (1:41)

And how it just radically transformed the global economy too.

SPEAKER_1 (1:45)

Yeah. Stretching from the textile mills of England all the way to the architecture of Egypt. And we'll get into how it spawned this high stakes, highly lucrative cat and mouse game on the high seas.

SPEAKER_2 (1:55)

Because it really was a game of cat and mouse.

SPEAKER_1 (1:57)

For sure. Because, you know, reading through our sources, it basically sounds like Lincoln hung a clothes sign on a continent that had no actual doors.

SPEAKER_2 (2:06)

That's a great way to put it. Because to understand the scope of the problem, you really have to look at the logistical cliff the Union Navy was staring down.

SPEAKER_1 (2:13)

So tell me about that, because we mentioned the three capable ships.

SPEAKER_2 (2:17)

Yeah. So the entire US. Navy at that moment technically had 42 active ships.

But they were scattered all over the globe protecting trade routes. And many of them were these aging, technologically obsolete sailing ships that were just useless against modern steam power.

SPEAKER_1 (2:33)

Oh, wow. Yeah. So they couldn't even catch anything if they tried.

SPEAKER_2 (2:36)

Exactly. And it gets worse. One vessel was physically stuck on Lake Erie and literally could not be moved to the ocean.

SPEAKER_1 (2:42)

Stuck.

SPEAKER_2 (2:43)

Yeah, stuck. And another one was on patrol literally missing somewhere off the coast of Hawaii.

They didn't even know where it was.

SPEAKER_1 (2:50)

I just I'm imagining pitching that to aborted directors, you know. You have a 3,500 mile coastline spanning the Atlantic and the Gulf of Mexico. Right. You have 12 major maritime hubs like New Orleans, Mobile and Charleston, plus like 180 minor ports of entry.

SPEAKER_2 (3:07)

It's just a nightmare to cover.

SPEAKER_1 (3:09)

It really is. How do you go from a skeletal outdated fleet to sealing off an entire coast practically overnight?

It feels like an aggressive tech start up bluffing to their investors.

SPEAKER_2 (3:21)

Oh, totally.

SPEAKER_1 (3:22)

Claiming they have this robust fully functional product when in reality it's just two guys coding in a garage hoping nobody looks under the hood.

SPEAKER_2 (3:29)

Yeah. Fake it till you make it. And the person tasked with building that product in real time was Navy Secretary Gideon Welles.

SPEAKER_1 (3:36)

So what did he do?

SPEAKER_2 (3:37)

Well he had to execute just an unprecedented mobilization. He immediately recalled all those foreign patrols.

SPEAKER_1 (3:43)

Right.

SPEAKER_2 (3:44)

And he launched a massive shipbuilding program in northern Navy yards. But building specialized warships takes a lot of time. Time they didn't have.

SPEAKER_1 (3:52)

Obviously. So what's the shortcut?

SPEAKER_2 (3:56)

The shortcut was deploying agents to major cities to just start buying up civilian vessels. Wait.

SPEAKER_1 (4:01)

Really? Just buying whatever was out there?

SPEAKER_2 (4:04)

Whatever floated, basically. We're talking merchant ships, passenger ferries, literally anything with a sturdy hull and a steam engine.

SPEAKER_1 (4:12)

That's insane.

SPEAKER_2 (4:13)
