text_A: In the War of 1812 some were lightly armed, sailing under Letters of Marque and Reprisal, when the type—exemplified by "Chasseur", launched at Fells Point, Baltimore in 1814—became known for her incredible speed; the deep draft enabled the Baltimore clipper to sail close to the wind. Clippers, running the British blockade of Baltimore, came to be recognized for speed rather than cargo space.
text_B: Did the Clippers failed at any task?
NO.
