A sword once given as a wedding gift in 1805 to his brother by Napoleon sells for more than $6.4M at an auction house in Paris. The buyer was not identified.
The sword was carried by Napoleon — who was not yet emperor — into the Battle of Marengo in June 1800, when he launched a surprise attack to push the Austrian army from Italy and seal France's victory.
It was declared a national treasure in 1978 by France, meaning that under French law it could be sold to a foreign buyer but had to remain in France for at least five months per year. Source: USAToday
