``My conviction is briefly this: The only sure way to defend and guard the border is to keep all rebel forces out of West Virginia, or, rather, out of all the northern portion of Virginia, and this can only be done by a sufficient force of cavalry, to be kept south of the Baltimore and Ohio Railroad. The late rebel raid . . . should be a lesson. . . .

``Cavalry is, I repeat, needed; 10,000 well-mounted men would give more effective security than three times the number of infantry.

``I have represented time and again to the military authorities at Washington my want . . . but it occurs to me to endeavor to enlist your efforts also, as the Executive of your great State, so much concerned in the endeavor to have this command supplied with more of this arm of defense and aggression. Will you co-operate with me? . . .'' (OR, I, XXV, II, 503).
