In the annals of excruciating misery during wartime, few events can compare with what befell Napoleon’s troops during his campaign in Russia. From Strange Maps we see the suffering and tragedy in graphic statistical form. (click image to enlarge)
“The best statistical graphic ever drawn“, is how statistician Edward Tufte described this chart in his authoritative work ‘The Visual Display of Quantitative Information’.
The chart, or statistical graphic, is also a map. And a strange one at that. It depicts the advance into (1812) and retreat from (1813) Russia by Napoleon’s Grande Armée, which was decimated by a combination of the Russian winter, the Russian army and its scorched-earth tactics. To my knowledge, this is the origin of the term ’scorched earth’ – the retreating Russians burnt anything that might feed or shelter the French, thereby severely weakening Napoleon’s army.
As a statistical chart, the map unites six different sets of data.
• Geography: rivers, cities and battles are named and placed according to their occurrence on a regular map.
• The army’s course: the path’s flow follows the way in and out that Napoleon followed.
• The army’s direction: indicated by the colour of the path, gold leading into Russia, black leading out of it.
• The number of soldiers remaining: the path gets successively narrower, a plain reminder of the campaigns human toll, as each millimetre represents 10.000 men.
• Temperature: the freezing cold of the Russian winter on the return trip is indicated at the bottom, in the republican measurement of degrees of réaumur (water freezes at 0° réaumur, boils at 80° réaumur).
• Time: in relation to the temperature indicated at the bottom, from right to left, starting 24 October (pluie, i.e. ‘rain’) to 7 December (-27°).Pause a moment to ponder the horrific human cost represented by this map: Napoleon entered Russia with 442.000 men, took Moscow with only 100.000 men left, wandered around its abandoned ruins for some time and escaped the East’s wintry clutches with barely 10.000 shivering soldiers. Those include 6.000 rejoining the ‘bulk’ of the army from up north. Napoleon never recovered from this blow, and would be decisively beaten at Waterloo under two years later.
