The important information brought to my notice by Operative Curtis, on his return from Richmond, concerning the character and working of the "Subterranean Headquarters," at once determined me on a plan of using the same body of men, or rather the information they carried, for the benefit of the Union forces, instead of allowing them to use it in the interests of the Confederates. To accomplish this, I detailed several members of my force, both at Washington and Baltimore, to co-operate with Curtis, whom I intended now should become an active agent of the rebels in carrying dispatches to and from Richmond. The plan was, in short, that all dispatches entrusted to him should be accurately copied, the copies to be delivered to his confederates, and the originals forwarded to their destination.

In war, as in a game of chess, if you know the moves of your adversary in advance, it is then an easy matter to shape your own plans, and make your moves accordingly, and, of course, always to your own decided advantage. So in this case, I concluded that if the information intended for the rebels could first be had by us, after that, they were welcome to all the benefit they might derive from them.

In a few days, then, having completed my arrangements, Curtis started to Richmond, by the way of Wilson's Landing and Glendale, he having decided that, provided as he was with his pass from the Secretary, it would be perfectly safe, and at the same time a much shorter route than by the way of Petersburgh.

Leaving him for the present, then, to make his way to Richmond as best he can, we will turn our attention to other persons and to other scenes. The interior of a comfortable farm-house, the place, and early evening the time.
