June 26 1862 Wrote Gen. Halleck, “News has just reached me, or reached me during the night, that [Conf. Col. William H.] Jackson’s forces came in on the railroad near Germantown [TN, about fifteen miles southeast of Memphis] yesterday and captured the train with all on board, and also the wagon train loaded with supplies for General Sherman’s division; also cut the road. Day before yesterday I heard of Jackson being 20 miles southeast from here, intending to make a raid upon this wagon train, with a view of destroying it, at their camping place for last night. I immediately issued orders for the cavalry here to accompany this train to their camp ground for last night, and if deemed advisable accompany them this morning to beyond danger.
“The wagon train left the evening this order was published, going out of the city to encamp. The additional escort followed in the morning, and with the usual cavalry stupidity took the wrong road, thus leaving the train protected only with the escort furnished by General Sherman. As this last force followed on after the capture it is not at all improbable that they too have been taken. My information is all from citizens who came in last night, and may not be strictly reliable.
“Accompanying the railroad train was a letter to yourself and one to General Sherman, which I am very sorry to have (these letters), particularly the former, fall into the hands of the rebels. Colonel Griegson, commander of the cavalry sent from here, has just returned from Germantown and discredits the reports of the captured of our trains. He says that Jackson’s men have been hovering along the line of the railroad in squads burning cotton; that cotton was burned yesterday at three or four places visited by him.
“An impression seems to prevail here that a force is collecting 35 miles southeast from here for the purpose of making an attack on this place and burning it.
“My force now here is small, having sent two regiments to re-enforce Colonel Fitch and to protect five steamers loaded with supplies for General Curtis’ command. Three steamers are now ready to start. I have had precautionary measures taken to protect the pilots from musketry.
“I reported to you the effective strength of this command, but you may not have received it. As my office and quarters have been moved to the suburbs of the city, and all the records are there, I cannot now give you the exact strength. I believe the entire effective force left, after re-enforcing Colonel Fitch, is about 4,000. It seems to me that one of the divisions of the Army of the Tennessee now at Corinth should move west, so as to strengthen this point by another division. This would enable me to hold Hernando or some suitable point on the railroad to Grenada.”
