The history of the world is peopled with dauntless men and women who refused to be "subdued" or "tamed" by fear. The word dauntless can be traced back to Latin domare, meaning "to tame" or "to subdue." When our verb daunt (a domare descendant adopted by way of Anglo-French) was first used in the 14th century, it shared these meanings. The now-obsolete "tame" sense referred to the taming or breaking of wild animals, particularly horses: an undaunted horse was an unbroken horse. Not until the late 16th century did we use undaunted with the meaning "undiscouraged and courageously resolute" to describe people. By then, such lionhearted souls could also be described as "undauntable" as well as "dauntless."
