Heavy artillery like this was of comparatively little use in repulsing
such an attack as Early might be expected to make. Not only were these
guns hard to move to points of danger, but in the summer of '64 there were
no trained artillerists to man them. Big as they were, they gave Early no
occasion for alarm.
