Diary of Alexander G. Downing: Sunday, October 11, 1863

We left this morning according to orders and marched fifteen miles, when we stopped to eat dinner. We then continued our march about five miles farther, and at 4 o'clock we reached the Black river bridge, just ten miles out from Vicksburg, thus making a circuit of twenty miles to reach this important point.
