Thomas Wentworth Higginson, Army Life in a Black Regiment

The opportunity at last arrived, and I shall never forget the glee with which, after several postponements, I finally rode forth, a little before midnight, on a night which seemed made for the purpose. I had, of course, kept my own secret, and was entirely alone. The great Southern fireflies were out, not haunting the low ground merely, like ours, but rising to the loftiest tree-tops with weird illumination, and anon hovering so low that my horse often stepped the higher to avoid them. The dewy Cherokee roses brushed my face, the solemn “Chuckwill's-widow” croaked her incantation, and the rabbits raced phantom-like across the shadowy road. Slowly in the darkness I followed the well-known path to the spot where our most advanced outposts were stationed, holding a causeway which thrust itself far out across the separating river,--thus fronting a similar causeway on the other side, while a channel of perhaps three hundred yards, once traversed by a ferry-boat, rolled between. At low tide this channel was the whole river, with broad, oozy marshes on each side; at high tide the marshes were submerged, and the stream was a mile wide. This was the point which I had selected. To ascertain the numbers and position of the picket on the opposite causeway was my first object, as it was a matter on which no two of our officers agreed.
