For the great plan of conquering Canada, Pitt chose young and ardent officers, with Amherst, distinguished for steadiness and self-control, as their commander-in-chief.
This steadiness may vary during the flight of the projectile, as the shot may be unsteady for some distance after leaving the muzzle, afterwards steadying down, like a spinning-top. Again, a may increase as the gun wears out, after firing a number of rounds.
After all care has been taken in laying and pointing, in accordance with the rules of theory and practice, absolute certainty of hitting the same spot every time is unattainable, as causes of error exist which cannot be eliminated, such as variations in the air and in the muzzle-velocity, and also in the steadiness of the shot in flight.
Meade, who, besides steadiness and ability, possessed the confidence of Lincoln and Halleck which Hooker had lacked.
He had well employed the short time at his disposal for training his men, and on the first field of Bull Run they won for themselves and their brigadier, by their rigid steadiness at the critical moment of the battle, the historic name of "Stonewall."
