May 24, 1862 - "I yield to no man in sympathy for the gallant men under my command; but I am obliged to sweat them tonight, so that I may save their blood tomorrow. The line of hills southwest of Winchester must not be occupied by the enemy's artillery. My own must be there and in position by daylight. … You shall however have two hours rest." –Thomas J. 'Stonewall' Jackson,
To Col. Sam Fulkerson, who reported on the weariness of their troops and suggested that they should be given an hour or so to rest from a forced march in the night. (24 May 1862); as quoted in Mighty Stonewall (1957) by Frank E. Vandiver, p. 250"
