_May '63_.--As I write this, the wounded have begun to arrive from Hooker's command from bloody Chancellorsville. I was down among the first arrivals. The men in charge told me the bad cases were yet to come. If that is so I pity them, for these are bad enough. You ought to see the scene of the wounded arriving at the landing here at the foot of Sixth street, at night. Two boat loads came about half-past seven last night. A little after eight it rain'd a long and violent shower. The pale, helpless soldiers had been debark'd, and lay around on the wharf and neighborhood anywhere. The rain was, probably, grateful to them; at any rate they were exposed to it. The few torches light up the spectacle. All around--on the wharf, on the ground, out on side places--the men are lying on blankets, old quilts, &c., with bloody rags bound round heads, arms, and legs. The attendants are few, and at night few outsiders also--only a few hard-work'd transportation men and drivers. (The wounded are getting to be common, and people grow callous.) The men, whatever their condition, lie there, and patiently wait till their turn comes to be taken up. Near by, the ambulances are now arriving in clusters, and one after another is call'd to back up and take its load. Extreme cases are sent off on stretchers. The men generally make little or no ado, whatever their sufferings. A few groans that cannot be suppress'd, and occasionally a scream of pain as they lift a man into the ambulance. To-day, as I write, hundreds more are expected, and to-morrow and the next day more, and so on for many days. Quite often they arrive at the rate of 1000 a day. A NIGHT BATTLE OVER A WEEK SINCE
