The day after I assumed command at Cairo a man came to me who said he was a scout of General Fremont.  He reported that he had just come from Columbus, a point on the Mississippi twenty miles below on the Kentucky side, and that troops had started from there, or were about to start, to seize Paducah, at the mouth of the Tennessee.  There was no time for delay; I reported by telegraph to the department commander the information I had received, and added that I was taking steps to get off that night to be in advance of the enemy in securing that important point.  There was a large number of steamers lying at Cairo and a good many boatmen were staying in the town.  It was the work of only a few hours to get the boats manned, with coal aboard and steam up.  Troops were also designated to go aboard.  The distance from Cairo to Paducah is about forty-five miles.  I did not wish to get there before daylight of the 6th, and directed therefore that the boats should lie at anchor out in the stream until the time to start.  Not having received an answer to my first dispatch, I again telegraphed to department headquarters that I should start for Paducah that night unless I received further orders.  Hearing nothing, we started before midnight and arrived early the following morning, anticipating the enemy by probably not over six or eight hours.  It proved very fortunate that the expedition against Jeff.  Thompson had been broken up.  Had it not been, the enemy would have seized Paducah and fortified it, to our very great annoyance.

When the National troops entered the town the citizens were taken by surprise.  I never after saw such consternation depicted on the faces of the people.  Men, women and children came out of their doors looking pale and frightened at the presence of the invader.  They were expecting rebel troops that day.  In fact, nearly four thousand men from Columbus were at that time within ten or fifteen miles of Paducah on their way to occupy the place.  I had but two regiments and one battery with me, but the enemy did not know this and returned to Columbus.  I stationed my troops at the best points to guard the roads leading into the city, left gunboats to guard the river fronts and by noon was ready to start on my return to Cairo.  Before leaving, however, I addressed a short printed proclamation to the citizens of Paducah assuring them of our peaceful intentions, that we had come among them to protect them against the enemies of our country, and that all who chose could continue their usual avocations with assurance of the protection of the government.  This was evidently a relief to them; but the majority would have much preferred the presence of the other army.  I reinforced Paducah rapidly from the troops at Cape Girardeau; and a day or two later General C. F. Smith, a most accomplished soldier, reported at Cairo and was assigned to the command of the post at the mouth of the Tennessee.  In a short time it was well fortified and a detachment was sent to occupy Smithland, at the mouth of the Cumberland.
