Recent DNA analysis of deceased soldiers' remains has shed new light on the devastating consequences of Napoleon's ill-fated 1812 invasion of Russia. Historians have long maintained that a combination of harsh winter conditions, hunger, and disease ravaged the Grande Armée, leading to the deaths of nearly 300,000 men. However, research suggests that two specific pathogens – Salmonella enterica Paratyphi C and Borrelia recurrentis – may have played a significant role in exacerbating the crisis.
The study, conducted by researchers in France and Estonia, analyzed DNA from the teeth of soldiers exhumed in Lithuania who were likely victims of infectious diseases. The analysis revealed evidence of the two pathogens, which are known to cause paratyphoid fever and relapsing fever respectively. Four of the soldiers tested positive for Salmonella enterica Paratyphi C, while two were infected with Borrelia recurrentis.
The findings are significant because they represent the first genetic evidence of Napoleon's soldiers being afflicted by these pathogens. Both diseases share symptoms with those described in historical records of the Grande Armée's retreat from Russia, including high fever, fatigue, and digestive problems. Given that many soldiers were already suffering from cold, hunger, and poor hygiene, it is likely that these pathogens further drained their strength.
While the study only investigated a small sample size of 13 soldiers, its findings suggest that infectious diseases could have contributed significantly to the devastation of Napoleon's campaign in Russia. As Nicolás Rascovan, co-author of the study, noted, "The presence of these previously unsuspected pathogens reveals that they could have contributed to the devastation of Napoleon's Grande Armée during its disastrous retreat in 1812."
The research also has broader implications for our understanding of infectious diseases and their role in historical events. By analyzing genetic data from historically relevant pathogens, scientists can gain valuable insights into the development of these illnesses and shed new light on infamous military failures like Napoleon's Russian campaign. The study's findings serve as a poignant reminder of the importance of considering the complex interplay between environmental factors, human health, and disease in historical events.
