The dense forests wholly or partly in which were fought so many battles of the Civil War, lay upon the earth in each autumn a thick deposit of dead leaves and stems, the decay of which forms a soil of surprising depth and richness. In dry weather the upper stratum is as inflammable as tinder. A fire once kindled in it will spread with a slow, persistent advance as far as local conditions permit, leaving a bed of light ashes beneath which the less combustible accretions of previous years will smolder until extinguished by rains. In many of the engagements of the war the fallen leaves took fire and roasted the fallen men. At Shiloh, during the first day's fighting, wide tracts of woodland were burned over in this way and scores of wounded who might have recovered perished in slow torture. I remember a deep ravine a little to the left and rear of the field I have described, in which, by some mad freak of heroic incompetence, a part of an Illinois regiment had been surrounded, and refusing to surrender was destroyed, as it very well deserved. My regiment having at last been relieved at the guns and moved over to the heights above this ravine for no obvious purpose, I obtained leave to go down into the valley of death and gratify a reprehensible curiosity.
