This Day in History: March 9

After successfully capturing British positions in Louisiana and Mississippi, Spanish General Bernardo de Galvez, commander of the Spanish forces in North America, turns his attention to the British-occupied city of Pensacola, Florida, on this day in 1781. General Galvez and a Spanish naval force of more than 40 ships and 3,500 men landed at Santa Rosa Island and begin a two-month siege of British occupying forces that becomes known as the Battle of Pensacola.
