"An attack of cavalry should be sudden, bold, and vigorous. The cavalry which arrives noiselessly but steadily near the enemy, and then, with one loud yell leaps upon him without a note of warning, and giving no time to form or consider anything but the immediate means of flight, pushing him vigorously every step with all the confidence of victory achieved, is the true cavalry; while a body of men equally brave and patriotic, who halt at every picket and reconnoiter until the precious surprise is over, is not cavalry."
