these ever grew into a battle. These affairs sprung from the desire
of each side to feel his antagonist, and had little result beyond
emphasizing the fact that behind each line of pickets lay a massed
and powerful army busily preparing for the inevitable conflict and

from one wing or division to another, and the substitution of General
Thomas for Gilbert as a corps commander. The army was thus compact
