第二次対仏大同盟
Negotiations between France and Britain to end the War of the Second Coalition resulted in the March 1802 Treaty of Amiens; although widely viewed as a short-lived truce, it gave Napoleon an opportunity to activate his plans for North America. In December 1801, 30,000 veteran French troops landed on Saint-Domingue, and soon after, Spain confirmed the transfer of Louisiana to France.
