A last stand, or a final stand, is a military situation in which a body of troops holds a defensive position in the face of overwhelming and virtually insurmountable odds. Troops may make a last stand due to a sense of duty; because they are defending a tactically crucial point; to buy time to enable a trapped army, person, or group of people to escape; due to fear of execution if captured; or to protect their leader(s). Last stands loom large in history, as the heroism and sacrifice of the defenders exert a large pull on the public's imagination. Some last stands have become a celebrated part of a fighting force's or a country's history, especially if the defenders accomplished their goals (or, in rare cases, defeated their attackers).
