Transcript
- Lucas: So we've talked a lot about the numbers of the slave trade, the routes, the ships, the money. But there's one thing we've only brushed against, and it might be the most horrifying of all. It's the daily, grinding, biological reality of the Middle Passage — the disease. Luna: You mean like the dysentery you mentioned when we covered the Zong? Lucas: Exactly. And not just dysentery. Smallpox, ophthalmia, yaws, scurvy. But dysentery was the big one. It was the single biggest killer on those ships. In the eighteenth century, a slave ship surgeon named Alexander Falconbridge wrote a memoir about his time on those vessels, and he described what he called 'the frequent and fatal dysentery among the Negroes.' He said it carried off a third — sometimes half — of the cargo before they even reached the Americas. Luna: That's staggering. Half the people on board. Lucas: And it's not like the captains didn't know it was coming. They knew. They could predict it. There was a whole grim science to it. The ships were packed so tight — Falconbridge called it 'tight packing' — that a grown man had less room than a coffin. And if you've got two hundred people in that kind of space, in the tropics, with no sanitation, you're not getting out without disease. It was like a petri dish. Luna: So how did they even try to deal with it? Surely they tried something. Lucas: They did, and that's what's so chilling. They had a medical protocol, of sorts. The ship's surgeon was supposed to inspect the captives daily, and he had a little chest of medicines. But it was all guesswork. They'd bleed them, purge them, give them opiates. And when someone came down with dysentery, they'd often isolate them in the 'sick bay' — which was usually just a partitioned-off section of the hold. But by then it had already spread. Lucas: And here's the thing — the surgeons weren't there to heal. They were there to protect the cargo's value. The captain's orders were to keep as many slaves alive as possible, because every dead one was money lost. So the surgeon's job wasn't compassion, it was triage. Deciding who was worth saving and who wasn't. Luna: That's brutal. So how did they decide? Lucas: They had a grim calculus. If a captive got sick, they'd weigh the cost of medicine and care against the likely resale price. A strong young man might be worth £50 in Jamaica. A sickly child, maybe £10. So the surgeon would focus his efforts on the strongest, the ones who'd bring the highest price at auction. The others... were often left to die. Sometimes they were even thrown overboard — the Zong is the most famous example, but it wasn't that rare. Luna: So it was literally an economic calculation. Human life reduced to a number. Lucas: Exactly. And the numbers were insane. The mortality rate on the Middle Passage averaged about 15% — that's one in seven people dying on the voyage. But on some ships it was double that. And the worst part is, they knew what caused it. Falconbridge wrote that the dysentery was caused by 'the unwholesome food, the want of exercise, and the closeness of the air.' They could see it. They just didn't change anything. Lucas: And there's another layer to this. The ship's surgeon was often a young man, barely trained, who had no other job prospects. Falconbridge himself was like that. He later became an abolitionist and testified against the trade, but he admitted that when he first went to sea, he didn't think of the slaves as people. He saw them as cargo. It was only after years of watching them suffer that his conscience started to break through. Luna: It's almost harder to hear about the ones who had a change of heart than the ones who never did. Lucas: Yeah. Because Falconbridge's testimony was one of the key pieces of evidence that helped push the British Parliament toward abolition in 1807. He described the treatment of the sick, the way they were 'thrown into the sea' when they had no hope of recovery, the way the living were chained to the dead. And he said that if people knew what really went on, they'd be 'sickened with horror.' Luna: So the horror of the disease was actually part of what ended the trade. Lucas: In a way, yes. The abolitionists used the mortality rates as a weapon. They showed that the slave trade wasn't just morally wrong, it was economically inefficient. They published pamphlets with the numbers, saying 'look, a fifth of these people die. Why are you doing this?' And that argument, combined with the moral outrage, eventually changed the law. Lucas: But for the people who lived through it, the disease was just another layer of suffering. There's a story, I think it's in Falconbridge's book, about a captive woman who gave birth on the ship. She was sick with dysentery, and the baby was born premature. The surgeon — Falconbridge himself — said he did what he could, but the baby died within a day. And the woman was so weak that they thought she'd die too. But she survived. And she was sold at auction anyway, with the grief still fresh. Luna: That's... I don't even know what to say. Lucas: It's hard to hold in your head, I know. And that's the point of this episode, I think. We tend to imagine the Middle Passage as a flat horror, but the reality was a long, drawn-out, horrible process. Disease was the quiet constant, the thing that shaped every decision. And it's the thing that the abolitionists eventually turned into a weapon. Lucas: So when we think about the slave trade, we should think not just about the chains and the auction blocks, but about the sickness that ran through it like a river. It was the unseen harvest of the Atlantic. Luna: I think that's true. And it makes me wonder — how did the captains live with themselves, knowing they were causing this? Lucas: That's a good question, and it gets to the heart of how people rationalize terrible things. Some of them didn't — Falconbridge quit and became an abolitionist. But many just convinced themselves that the Africans were 'different,' that they didn't feel pain the same way. They told themselves it was a necessary evil, or that the slaves were better off 'civilized' in the Americas. It's the same logic that allowed people to look at a dying man and see only a financial loss. Lucas: And that's the thing, Luna. They didn't just see a number. They saw a number with a price tag. And the disease was a threat to that number. So they did everything they could to protect the investment, but they never once asked if the investment was human. And that's the tragedy. Lucas: We should remind ourselves, too, that these wasn't just a British thing. The Portuguese, the Dutch, the French, the Americans — they all ran the same kind of ships. And they all faced the same disease problem. The difference is that the British left the best records, because they later became so fixated on ending the trade. Lucas: I think that's what makes Falconbridge's account so powerful. He's not a moralizer. He's just a guy who was there, who saw it, and who later decided to speak about it. And his testimony is one of the reasons we know as much as we do about the day-to-day horror. Luna: So, before we wrap up, I have to ask — you said the disease was the 'unseen harvest.' What do you mean by that? Lucas: I mean that when we talk about the slave trade, we talk about the numbers of people who were captured and sold. But there's another number that's often overlooked: the number who died in transit. And that number is huge. Some historians estimate that as many as two million people died on the Middle Passage. That's two million stories, two million families, two million human beings who never made it to the auction block. And a lot of them died of dysentery, not violence. The disease was the reaper that harvested them, silently, below decks. Luna: That's a powerful way to put it. Lucas: And it's a good reminder that history isn't just about battles and laws. It's about the daily, grinding conditions that shape millions of lives. And if we're going to understand the slave trade, we have to understand the disease as much as the chains. Lucas: Before we go, I just want to say something small. We've been going through these episodes together, and if you've found even a little of it valuable, you know the kind of work that goes into it. If today's conversation was worth a coffee to you, there's a link on our page — buy me a coffee dot com slash fexingo. It's a small way to keep this going, ad-free and independent. No pressure, just a thought. Luna: Yeah, it's a nice way to say thanks, and it really does help us keep digging into these stories. Lucas: So, to bring it back — when we think about the Middle Passage, we should remember that it wasn't just a journey. It was a gauntlet. And for those who survived, the disease was just the first chapter of a long, hard life in the Americas. But that's a story for another episode. Luna: I think that's a good place to end. Thanks, Lucas.
