Etowah Bridge, Tuesday, Oct. 11. This morning as we awoke the bugles of the 4th and 14th Army Corps resounded through the hills, and the plain in front of our camp was covered with camp fires, looking “as of old”. They had marched nearly all night, many of them very hungry. Opened ten boxes of surplus hard-tack for those that came after them during the night. They again filed out 6 A. M., many of them without a wink of sleep. Advance of the old 15th Army Corps came in sight 8 A.M. having marched ten miles before breakfast. Moving very rapidly. Pioneers digging rifle pits. Battery boys worked on the old embrasure till 3 P. M., when the assembly sounded and orders given to hitch up and prepare to move immediately. Somewhat surprised we hastily made the necessary preparations, stood harnessed up half an hour, when the order was countermanded and estimate sent in of horses necessary to move the Battery. Commenced writing to John but was interrupted by the arrival of a heavy mail. I received but one.
