We were doing what we could with men and women who could be spared from our boats, which were all full of wounded, to provide for those on the Webster and ashore. Before night, the Spaulding having arrived, I brought up fourteen fresh men and the ladies, with two physicians, and they have been steadily at work, and up to this time (noon of Tuesday) operating, dressing, feeding, and, with the assistance of other volunteers, bringing the wounded from the cars to the boat.

The Vanderbilt came more than a week ago, empty, and assigned to hospital service. She came to the wharf that had been built, at my request, for the use of the Sanitary Commission, refused to leave at my request, and has occupied it to our exclusion ever since. She has had surgeons and a large detail of soldiers on board, and I had been informed that she was reserved for the transportation of wounded, by your orders. Neither those on board of her nor those at the camp hospital appeared at the railroad, or lent any assistance, to my knowledge, to the care of the wounded, until, under advice from Captain Sawtelle and myself, Dr. ——, who had received your telegram disacknowledging him as having any official position, requested the surgeon in charge to bring the Vanderbilt to the railroad wharf. Having our boats and the removal of the wounded in ambulance trains to attend to, I did not think it necessary to inquire if she were prepared for hospital duty, knowing that she had been a week idle, and previously in hospital service; but late this morning I was informed that she had not any commissary, or even necessary medical stores on board, and nothing whatever was being prepared for the sustenance of the patients.

We have provided bread and molasses, for the want of anything else ready. We have been also called upon for, and are providing, lint and bandages, &c., &c.

The Elm City and Knickerbocker are both off, the Spaulding is yet to discharge the commissary stores with which she came loaded, and there is not a boat here now which can carry wounded, nor is there a tent pitched for them.

I have no time to be more full and exact. I have called on Colonel Ingalls to establish a cooking arrangement on shore, and shall try to get beef for soup.

I hear that more wounded are arriving. God knows what will be done with them.

As the telegraph refuses to send any messages to you to-day, being fully occupied with the General's business, I shall, if possible, send this to you this evening by a special messenger.

I am very faithfully, &c.
