_June 23, Sundown._--As I sit writing this paragraph I see a train of
about thirty huge four-horse wagons, used as ambulances, fill'd with
wounded, passing up Fourteenth street, on their way, probably, to
Columbian, Carver, and Mount Pleasant hospitals. This is the way the men
come in now, seldom in small numbers, but almost always in these long,
sad processions. Through the past winter, while our army lay opposite
Fredericksburg, the like strings of ambulances were of frequent
occurrence along Seventh street, passing slowly up from the steamboat
wharf, with loads from Aquia creek.
