On the 7th of August I further depleted my army by sending the 13th corps, General Ord commanding, to Banks.  Besides this I received orders to co-operate with the latter general in movements west of the Mississippi.  Having received this order I went to New Orleans to confer with Banks about the proposed movement.  All these movements came to naught.

During this visit I reviewed Banks’ army a short distance above Carrollton.  The horse I rode was vicious and but little used, and on my return to New Orleans ran away and, shying at a locomotive in the street, fell, probably on me.  I was rendered insensible, and when I regained consciousness I found myself in a hotel near by with several doctors attending me.  My leg was swollen from the knee to the thigh, and the swelling, almost to the point of bursting, extended along the body up to the arm-pit.  The pain was almost beyond endurance.  I lay at the hotel something over a week without being able to turn myself in bed.  I had a steamer stop at the nearest point possible, and was carried to it on a litter.  I was then taken to Vicksburg, where I remained unable to move for some time afterwards.

While I was absent General Sherman declined to assume command because, he said, it would confuse the records; but he let all the orders be made in my name, and was glad to render any assistance he could.  No orders were issued by my staff, certainly no important orders, except upon consultation with and approval of Sherman.

On the 13th of September, while I was still in New Orleans, Halleck telegraphed to me to send all available forces to Memphis and thence to Tuscumbia, to co-operate with Rosecrans for the relief of Chattanooga.  On the 15th he telegraphed again for all available forces to go to Rosecrans.  This was received on the 27th.  I was still confined to my bed, unable to rise from it without assistance; but I at once ordered Sherman to send one division to Memphis as fast as transports could be provided.  The division of McPherson’s corps, which had got off and was on the way to join Steele in Arkansas, was recalled and sent, likewise, to report to Hurlbut at Memphis.  Hurlbut was directed to forward these two divisions with two others from his own corps at once, and also to send any other troops that might be returning there.  Halleck suggested that some good man, like Sherman or McPherson, should be sent to Memphis to take charge of the troops going east.  On this I sent Sherman, as being, I thought, the most suitable person for an independent command, and besides he was entitled to it if it had to be given to any one.  He was directed to take with him another division of his corps.  This left one back, but having one of McPherson’s divisions he had still the equivalent.

Before the receipt by me of these orders the battle of Chickamauga had been fought and Rosecrans forced back into Chattanooga.  The administration as well as the General-in-chief was nearly frantic at the situation of affairs there.  Mr. Charles A. Dana, an officer of the War Department, was sent to Rosecrans’ headquarters.  I do not know what his instructions were, but he was still in Chattanooga when I arrived there at a later period.
