As the Revolutionary and Napoleonic Wars progressed, the casualty rates in battles increased exponentially: at Fleurus they were 6% of the total number of men engaged, at Austerlitz 15%, at Eylau 26%, at Borodino 31% and at Waterloo 45%. This was partly because with ever-larger armies being raised, battles tended to last longer – Eylau was Napoleon’s first two-day engagement since Arcole; Eggmühl, Aspern-Essling and Wagram in 1809, Dresden in 1813 were also two and Leipzig in 1813 went on for three – but mainly because of the huge increase in the numbers of cannon present.
