Recent DNA analysis reveals the shocking truth behind Napoleon's ill-fated Russian campaign, exposing a darker truth than previously thought.
Historians have long pointed to typhus as a leading cause of death among Napoleon's soldiers, but new research has uncovered that enteric and relapsing fever may have been responsible for thousands more fatalities. The study, conducted by scientists at France's Institut Pasteur, analyzed the remains of 13 soldiers found in a mass grave in Vilnius, Lithuania.
The researchers extracted DNA from the soldiers' teeth and sequenced it to identify any bacterial pathogens present. To their surprise, none of the men showed signs of typhus, but rather fragments of two other bacteria: Salmonella enterica and Borrelia recurrentis. The former is responsible for enteric or typhoid fever, while the latter causes relapsing fever.
Enteric fever's name references its symptomatic similarities with typhus, and it was not recognized as a distinct disease until later in the 19th century. Relapsing fever is often transmitted by body lice, which would have been present among Napoleon's soldiers due to their poor hygiene conditions.
The discovery of these two bacteria casts doubt on the long-held narrative that typhus was the primary cause of death among Napoleon's troops. The researchers believe that the use of different sequencing technologies in earlier studies may have led to false positives and misidentifications.
Moreover, the study has revealed an unexpected connection between the strain of Borrelia recurrentis found in Napoleon's soldiers and a similar lineage discovered 2,000 years ago in Iron Age Britain. This finding suggests that the disease was present in Europe for much longer than previously thought and highlights the importance of studying ancient DNA to better understand historical events.
Overall, this study offers a fresh perspective on one of history's greatest military blunders, revealing that the true enemy may have been not just external forces but also internal health threats.
