DNA reveals the real killers that brought down Napoleon's army

>Rather than the typhus pathogen, the team found traces of Salmonella enterica and Borrelia recurrentis, both of which can trigger symptoms such as high fever, fatigue and digestive problems.

It is interesting that although Napoleon captured Moscow, the capital at that time was in Saint-Petersburg. Why didn't he go to the capital? This painting depicts Napoleon hopelessly waiting for a delegation from Russian Emperor with burning city in the background [1].

The capital was better fortified and the French wanted food and loot. So softer target sounds nice, especially if you think this crushes morale immediately and don't believe the opposition will go scorched earth (but they did).

Your comment has me remember a great graph of his army disintegrating. It’s such a good visualisation.

His goal was the Russian army, they retreated towards Moscow and he pursued.

cpleppert

A bunch of reasons.

1. Napoleon's goal was to pursue and defeat the Russian army in the field, not necessarily capture cities. Going north would have meant releasing the pressure on the main russian field armies and let them engage his main force at their discretion while exposing his flank.

2. St. Petersburg remained the political and economic capital of Russia; St. Petersburg never displaced Moscow in real world importance.

3. St. Petersburg was shielded from land and sea with prepared fortifications on both and Napoleon lacked a fleet to effectively blockade it.

4. Its in the middle of a very dense forest and swamp, not the the best logistics and ability to maintain a siege.

The Nazis made the same choice in WWII and even though they were able to control the Baltics and had Finland as an ally never seriously threatened to take the city.

zemptime

One theory I've heard for this, and sorry I don't remember the source, is that Napoleon suspected if he truly did take down the Russian royalty then he expected the rest of European royalty to unite and attack attack him.

codedokode

As I remember, after French revolution, there were coalitions of foreign monarchies with the goal of punishing France [1].

Also what surprises me, after years of several revolutions and chaos in France, how could Napoleon gather such a large army.

itsnowandnever

he essentially invented the modern concept of conscription. there were press gangs and conscription-like things all through history but for the most part soldiers were professionals

> Also what surprises me, after years of several revolutions and chaos in France, how could Napoleon gather such a large army.

Conscription + France was basically the China of Europe at that point: it was almost as populated as the rest of Europe combined.

France then had a very, very, early demographic transition which dramatically limited its population. Had France followed the demographic path of England or Germany, France would have around 250M inhabitants today.

paganel

Because Napoleon didn't want to depose the Tsar, much less to conquer Russia, he just wanted to impose his (Napoleon's) will on the Tsar and on Russia as a whole when it came to strictly imposing the Continental Blockade against the British. A heavily defeated Russia wouldn't have helped him into achieving that.

codedokode

It is also interesting that Russian army officers could talk to French without a translator, because Napoleon invasion happened in the period of "westernization", started by Peter the Great. The buildings were built in a Western style, calendar was changed to European, government, army and fleet were reformed, noblemen were required to shave their traditional beards, wear western-style clothes, used French language, and danced to classical Western music in events like balls and fought duels.

username332211

It's a lot less interesting once you look trough the names of senior Russian officers - de Tolly, Bagration, von Benningsen, Wittgenstein, Osterman-Tolstoy.

One begins to suspect that the reason Kutuzov replaced Barkley was for a sort of reverse-DEI reasons.

codedokode

I remember reading one of Peter the Great's orders regarding creating 10 new units in the army. Out of names of the commanders only 3-4 were Russian. So hiring foreign talent was also part of westernization.

Check out the perfect set of teeth on the skull of the soldier shown in the article. Amazing how human dental health has changed since then.

kace91

We’re talking about a foot soldier on Napoleon’s army, easy to keep a good set considering he could be 18-25.

hermitcrab

And probably with limited access to sugar.

boomboomsubban

Probably, cane sugar was unavailable due to blockades and the Napoleonic expansion of beet sugar was only just starting.

manoDev

1. The soldier probably died young

2. Good dental health has always been part of the screening to join a professional army

tgv

They were looking to analyze teeth. This might be selection bias.

bluedino

Due to "softer" diets and all the sugar, right?

travisjungroth

Harder diets were more common in ancient humans, and straighten teeth in childhood. I don’t know what the diet was like in 1800.

Link to the actual report: https://www.cell.com/current-biology/fulltext/S0960-9822(25)...

I think it's weird that what was submitted to HN was a blog post on what claims to be a web site about vaccines, but has no contact information.

Is this the new thing? Have AI rewrite a news article and spam news aggregators to get inbound links from places like HN to boost your domain's profile and then sell it?

Actual news article (submitted 16 hours earlier): https://www.washingtonpost.com/science/2025/10/24/napoleons-...

Note that the actual paper does not make the claim from the title, and that they "recovered and sequenced ancient DNA from the teeth of 13 soldiers" (one molar each) from one site only, which means other origins cannot be discarded, especially since these pathogens could only be found in 5 of 13.

Saved you a click

floam

How did you save me a click? Those bits were in this article. The guy that located the original report saved me some time.

You could only save somebody time if they skipped the content and started doing comments on HN anyhow, but that’s not all the information either, just a couple key points.

Examples from 13 soldiers out of 500,000 — very representative, indeed.

"one that would see his army decimated by cold, hunger and disease."

2 things: A)decimated means 1 in 10, not 9 in 10. B) according to the wiki article, Napoleon had already lost 75% of his initial fighting force by the time he got to Moscow, before the withdrawal.

I am not sure an article on biology should include much history--I would certainly hope it did a better job on the biology...

From https://www.merriam-webster.com/dictionary/decimate

Decimate is a word that often raises hackles, at least those belonging to a small but committed group of logophiles who feel that it is commonly misused. The issue that they have with the decline and fall of the word decimate is that once upon a time in ancient Rome it had a very singular meaning: “to select by lot and kill every tenth man of a military unit.” However, many words in English descended from Latin have changed and/or expanded their meanings in their travels. For example, we no longer think of sinister as meaning “on the left side,” and delicious can describe things both tasty and delightful. Was the “to kill every tenth man” meaning the original use of decimate in English? Yes, but not by much. It took only a few decades for decimate to acquire its broader, familiar meaning of “to severely damage or destroy,” which has been employed steadily since the 17th century.

mathgradthrow

The more language is allowed to drift, the harder it becomes to read old language. I think this is a particularly silly case, but in general, the complaint that people are misusing words shouldn't be met with "It's impossible to misuse words", which this argument implicitly is.

soared

No one allows or disallows language to drift, there are no language enforcers. This argument is not “it’s impossible” but rather it’s pedantic to claim a word is misused, when it’s been used this way for hundreds of years and so the original definition is no longer applicable.

ciupicri

Which language, Latin or English? Who says that in English it needs to have the same meaning as in Latin?

Heck, I've reminded about false friends. For example library ("librărie") in Romanian is the place where you buy books, not rent them.

MontyCarloHall

You are figuratively killing me with your literalism.

hollerith

These days some would've written, "you are literally killing me . . ." (which I find deplorable).

kaechle

Using "literally" figuratively or, more precisely, as a hyperbolic intensifier [0], is a tradition employed by notable English writers who lived and died long before you were born.

ggambetta

And someone would have replied "I could care less" (incorrectly implying they do care, even if it's a little bit) :(

cenamus

Look in any dictionary and you'll find that that decimate means to devastate aswell.

Language is what people speak not what people proscribe in books or the internet.

jjallen

Exactly. If it is used a certain way by enough people, that is also an accepted definition. Dictionaries lag actual speech and language I suppose.

aleph_minus_one

> If it is used a certain way by enough people, that is also an accepted definition.

This mentality seems to be prevalent in the USA, in Germany, on the opposite, many people see this topic differently - just because a lot of people use a certain word/term wrong does not make it right.

tgv

If frequency of use is an argument, one could argue that to decimate might not even be a word.

kaechle

Correct. To decimate is the infinitive form of the verb decimate.

card_zero

Prescribe, and it's both of these things.

Jedd

Yes, that phrase stuck out to me also.

Apologists for language attrition will assert that converging language into a handful of very simple words is doubleplusgood, and we should embrace the dumbification because that's 'just how languages work'.

But for a historical article, I did expect a slightly more nuanced take.

soared

Why is this new word “dumbification” and not “smartification”?

Great day Borodin

We are brotherly feasts commemorating,

firmly: “Were the tribes,

Disaster threatening Russia;

Not all eh Europe there was?

Whose star led her!..

But we began to train hard pyatoyu

And chest took the pressure

tribes, obedient to the will of the proud,

And is was an unequal dispute.

And what? a disastrous escape,

kichas, they have forgotten now;

Lost Russian bayonet and snow,

Pogrebshy their glory in the desert.

Familiar feast beckons them again -

Chmielna for them Slavyanov blood;

But it will be hard for a hangover;

But guests will long dream

on close, cold Novosel,

Under the northern cereal fields!

It seems that computer translation is not good enough to parse Pushkin's poems yet. I tried ChatGPT, the translation is at least readable, but written in a dumbed down language. Yours is not even readable.
