And now commenced my apprenticeship to running a Secession railroad train, with a Rebel regiment on board. The engine behaved admirably, and I began to feel quite safe, for she obeyed every command I gave her, as if she acknowledged me her rightful lord. I could not but be startled at the position in which I was placed, holding in my hand the lives of more than a thousand men, running a train of twenty-five cars over a road I had never seen, running without a head-light, and the road so dark that I could only see a rod or two ahead, and, to crown all, knowing almost nothing of the business. Of course I ran slowly, about ten miles an hour, and never took my hand off the throttle or my eye from the road. The colonel at length grew confident, and almost confidential, and did most of the talking, as I had no time for conversation. When we had run about thirty miles, and every thing was going well, Colonel Williams concluded to walk back, on the top of the box-cars, to a passenger car which was attached to the rear of the train and occupied by the officers. This somewhat hazardous move he commenced just as we struck a stretch of trestlework which carried the road over a gorge some fifty feet deep. As the locomotive reached the end of the trestlework the grade rose a little, and I could see through, or in, a deep cut which the road ran into, an obstruction. What it was, or how far ahead, I had almost no conception; but quick as thought--and thought is quick as lightning in such circumstances--I whistled for the brakes, shut off the steam, and waited the collision. I would have reversed the engine, but a fear that a reversal of its action would crowd up the cars on the trestlework and throw them into the gorge below, forbade; nor was there wisdom in jumping off, as the steep embankments on either side would prevent escape from the wreck of the cars when the collision came. All this was decided in an instant of time, and I calmly awaited the shock which I saw was unavoidable. Though the speed, which was very moderate before, was considerably diminished in the fifty yards between the obstacle and the head of the train, I saw that we would certainly run into the rear of another train, which was the obstruction I had seen. The first car struck was loaded with hay and grain. My engine literally split it in two, throwing the hay right and left, and scattering the grain like chaff. The next car, loaded with horses, was in like manner torn to pieces, and the horses piled upon the sides of the road. The third car, loaded with tents and camp equipage, seemed to present greater resistance, as the locomotive only reached it, and came to a stand-still.
