Friday, 5th—It is quite warm. We left our bivouac at 3 a. m. and by 6 o’clock had crossed the Roanoke river. It is a fine stream. One of our drivers had an exciting experience in crossing the river last night, over the pontoon bridge. When he reached the middle of the bridge his leading mules became frightened at the cracks between the boards and turned right around, upsetting the whole thing, and the six mules, wagon and all went overboard. When the driver saw what was going to happen, quick as a flash, he dropped down upon the bridge between the wheel mules and the wagon, thus saving himself. The mules and wagon were never seen again, as the Roanoke is very deep. We crossed the State line into old Virginia at 6:30 this morning. At 1 p. m. we crossed the Meherrin river and after marching twenty-six miles for the day went into bivouac. We have fine roads. News came that the two men who killed the president and stabbed Seward had been shot. All is quiet.
