d not yet begun, for while seated at my office door,
with nothing further to do until it was time to start for the front, I
saw an officer of rank approaching, who proved to be Colonel Jefferson
C. Davis. I had never met him before, but he introduced himself by
handing me an order for him to proceed to Jefferson City and relieve me
of the command. The orders directed that I should report at department
headquarters at St. Louis without delay, to receive important special
instructions. It was about an hour before the only regular train of the
day would start. I therefore turned over to Colonel Davis my orders,
and hurriedly stated to him the progress that had been made to carry out
the department instructions already described. I had at that time but
one staff officer, doing myself all the detail work usually performed by
an adjutant-general. In an hour after being relieved from the command I

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 t
