### Unraveling the Mysteries of Napoleon's 1812 Retreat: New DNA Insights Recent studies of ancient DNA from soldiers' remains have shed light on the catastrophic retreat of Napoleon Bonaparte's army from Russia in 1812. This research, which analyzed DNA extracted from the teeth of soldiers found in a mass grave in Lithuania, reveals that the army faced not only the harsh winter and enemy attacks but also deadly pathogens that contributed significantly to their demise. The findings challenge long-held beliefs about the causes of the army's collapse, particularly the assumption that typhus was the primary killer. ### Understanding the Hypothesis and Structure of the Findings 1. **Pathogen Identification**: The research identified two unexpected pathogens—**Salmonella enterica** and **Borrelia recurrentis**—as key contributors to the soldiers' deaths, overturning the previous belief that typhus was the main cause of mortality during the retreat [https://www.webpronews.com/dna-reveals-salmonella-and-relapsing-fever-in-napoleons-1812-soldiers]. 2. **Medical Complexity**: The study highlights the medical challenges faced by the Grande Armée, indicating that enteric and relapsing fevers were prevalent, complicating the soldiers' already dire situation [https://www.nbcnews.com/science/science-news/dna-reveals-fevers-killers-napoleons-doomed-army-rcna239730]. 3. **Historical Context**: The findings provide a nuanced understanding of the retreat, which saw approximately 300,000 soldiers perish from a force that initially numbered around 600,000 [https://www.straitstimes.com/world/europe/dna-from-old-mass-grave-reveals-pathogens-that-beset-napoleons-army-in-1812]. ### Supporting Evidence and Data from the Research - **Pathogen Details**: - **Salmonella enterica**: Linked to paratyphoid fever, which can cause severe gastrointestinal distress. - **Borrelia recurrentis**: Associated with relapsing fever, characterized by recurrent episodes of fever and severe illness [https://www.webpronews.com/dna-reveals-salmonella-and-relapsing-fever-in-napoleons-1812-soldiers]. - **Impact on Troops**: The combination of these diseases, along with the brutal winter conditions and logistical failures, created a perfect storm that decimated the army [https://www.livescience.com/archaeology/dna-reveals-what-killed-napoleons-soldiers-during-their-disastrous-retreat-from-russia-in-1812]. ### Conclusion: A New Perspective on Napoleon's Defeat The recent DNA analysis of Napoleon's soldiers provides critical insights into the factors that led to the catastrophic losses during the 1812 retreat from Russia. 1. **Key Findings**: - The identification of **Salmonella enterica** and **Borrelia recurrentis** as significant pathogens challenges the long-standing narrative that typhus was the primary cause of death [https://www.webpronews.com/dna-reveals-salmonella-and-relapsing-fever-in-napoleons-1812-soldiers]. 2. **Broader Implications**: - Understanding the medical complexities faced by the Grande Armée offers valuable lessons for modern military and public health strategies, particularly in managing outbreaks in vulnerable populations [https://www.nbcnews.com/science/science-news/dna-reveals-fevers-killers-napoleons-doomed-army-rcna239730]. 3. **Historical Significance**: - This research not only enriches our understanding of a pivotal moment in European history but also emphasizes the role of infectious diseases in military campaigns [https://www.straitstimes.com/world/europe/dna-from-old-mass-grave-reveals-pathogens-that-beset-napoleons-army-in-1812]. In summary, the combination of harsh environmental conditions and the presence of lethal pathogens played a crucial role in the downfall of Napoleon's army, reshaping our understanding of this historical event.
