Meanwhile the three wooden gunboats had not been idle during the preparation of the main ironclad fleet. Arriving at Cairo, as has been stated, on the 12th of August, the necessity for action soon arose. During the early months of the war the State of Kentucky had announced her intention of remaining a neutral between the contending parties. Neither of the latter was willing to precipitate her, by an invasion of her soil, into the arms of the other, and for some time the operations of the Confederates were confined to Tennessee, south of her borders, the United States troops remaining north of the Ohio. On September 4th, however, the Confederates crossed the line and occupied in force the bluffs at Columbus and Hickman, which they proceeded at once to fortify. The military district about Cairo was then under the command of General Grant, who immediately moved up the Ohio, and seized Paducah, at the mouth of the Tennessee River, and Smithland, at the mouth of the Cumberland. These two rivers enter the Ohio ten miles apart, forty and fifty miles above Cairo. Rising in the Cumberland and Alleghany Mountains, their course leads through the heart of Tennessee, to which their waters give easy access through the greater part of the year. Two gunboats accompanied this movement, in which, however, there was no fighting. On the 10th of September, the Lexington, Commander Stembel, and Conestoga, Lieutenant-Commanding Phelps, went down the Mississippi, covering an advance of troops on the Missouri side. A brisk cannonade followed between the boats and the Confederate artillery, and shots were exchanged with the gunboat Yankee. On the 24th, Captain Foote, by order of General Fremont, moved in the Lexington up the Ohio River to Owensboro. The Conestoga was to have accompanied this movement, but she was up the Cumberland or Tennessee at the time; arriving later she remained, by order, at Owensboro till the falling of the river compelled her to return, there being on some of the bars less water than she drew. A few days later this active little vessel showed herself again on the Mississippi, near Columbus, endeavoring to reach a Confederate gunboat that lay under the guns of the works; then again on the Tennessee, which she ascended as far as the Tennessee State Line, reconnoitring Fort Henry, subsequently the scene of Foote's first decisive victory over the enemy. Two days later the Cumberland was entered for the distance of sixty miles. On the 28th of October, accompanied by a transport and some companies of troops, she again ascended the Cumberland, and broke up a Confederate camp, the enemy losing several killed and wounded. The frequent appearances of these vessels, while productive of no material effect beyond the capture or destruction of Confederate property, were of service in keeping alive the attachment to the Union where it existed. The crews of the gunboats also became accustomed to the presence of the enemy, and to
