was on my way to St. Louis, leaving my single staff officer(*6) to
follow the next day with our horses and baggage.

The "important special instructions" which I received the next day,
assigned me to the command of the district of south-east Missouri,
embracing all the territory south of St. Louis, in Missouri, as well as
all southern Illinois. At first I was to take personal command of a
combined expedition that had been ordered for the capture of Colonel
Jeff. Thompson, a sort of independent or partisan commander who was
disputing with us the possession of south-east Missouri. Troops had
been ordered to move from Ironton to Cape Girardeau, sixty or seventy
miles to the south-east, on the Mississippi River; while the forces at
Cape Girardeau had been ordered to move to Jacksonville, ten miles out
towards Ironton; and troops at Cairo and Bird's Point, at the junction
of the Ohio and Mississippi rivers, were to hold themselves in readiness
to go down the Mississippi to Belmont, eighteen miles below, to be moved
west from there when an officer should come to command them. I was the
officer who had been selected for this purpose. Cairo was to become my
headquarters when the expedition terminated.

In pursuance of my orders I established my temporary headquarters at
Cape Girardeau and sent instructions to the commanding officer at
Jackson, to inform me of the approach of General Prentiss from Ironton.
Hired wagons were kept moving night and day to take additional rations
to Jackson, to supply the troops when they started from there. Neither
General Prentiss nor Colonel Marsh, who commanded at Jackson, knew their
destination. I drew up all the instructions for the contemplated move,
and kept them in my pocket until I should hear of the junction of our
troops at Jackson. Two or three days after my arrival at Cape
Girardeau, word came that General Prentiss was approaching that place
