In 1799 the Prussian naturalist Alexander von Humboldt and the French botanist Aimé Bonpland sailed for Spain's American realms and spent five years measuring, collecting and climbing across them. They watched electric eels fight wild horses in Venezuela, pushed up Chimborazo, watched a planet cross the Sun from Peru and ended as Jefferson's guest at the White House.
This route follows eight stops from the landing at Cumaná to Washington in 1804. Several pins are approximate because the sources name a region or river rather than one spot.
In September 1799 the Russian field marshal Suvorov led his army into Switzerland to join the Allied forces, only to find his allies failing him. He fought through the Alps, crossed high passes and ended in Chur.
The route follows the march from Taverne to Chur. Dates are Gregorian (New Style), and pins mark villages or passes rather than battlefields.
On 26 February 1815 Napoleon slipped away from Elba with some 1,000 men. Within a month he was back in the Tuileries, and by mid-July he had surrendered to the Royal Navy.
The route follows him stop by stop: his villa on Elba, the landing at Golfe-Juan, the meeting at Laffrey and the entry into Grenoble on the Route Napoléon, the Tuileries, the farms of Hougoumont and La Haye Sainte at Waterloo, then Malmaison and Île d'Aix, where his journey ended. The pins at Golfe-Juan and Grenoble mark the towns, not exact spots.
