Answer. Most gallantly, and with success. The conduct of Colonel Hicks and his entire command was noble in the highest degree. Question. How did his colored troops behave? Answer. As well as the rest. Colonel Hicks thus refers to them in his official report: "I have been one of those men who never had much confidence in colored troops fighting, but those doubts are now all removed, for they fought as bravely as any troops in the fort." Question. Why was the city shelled and set on fire? Answer. Our small force retired within the fort; the rebels took possession of the town, and from adjacent buildings their sharpshooters fired upon us. It was necessary to dislodge them. The gunboats Peosta, Captain Smith, and Paw Paw, Captain O'Neal, and the fort drove them out, necessarily destroying property. Most of the inhabitants being still rebel sympathizers, there was less than the usual regret in performing the duty. Question. What became of the enemy after the repulse? Answer. They went south, and on the 26th I was notified by Colonel Hicks and by Colonel Lawrence that they were approaching Columbus. Question. What was done? Answer. I went to Columbus again, with such men as could be withdrawn from Cairo, and awaited an attack, but none was made. We were too strong, of which rebels in our midst had probably advised them. Question. Do you permit rebels to remain within your lines? Answer. Of course; after they have taken the oath. Question. What is done in case they violate, by acting as spies, for instance? Answer. I don't like to acknowledge that we swear them over again, but that is about what it amounts to. Question. What became of your garrison at Hickman? Answer. It was but 14 miles from Union City; too weak for defence, and unimportant. Having no re-enforcements to spare, I brought away the garrison. Question. Was Union City important as a military post? Answer. I think not, except to keep the peace and drive out guerillas. The railroad was operated to that point at the expense of the government, being used in carrying out supplies, which went mostly into disloyal hands, or were seized by Forrest. The road from Paducah to Mayfield was used by its owners. Enormous quantities of supplies needed by the rebel army were carried to Mayfield and other convenient points, and passed into the hands of the rebel army. I found this abuse so flagrant and dangerous that I made a stringent order stopping all trade. I furnish a copy herewith, making it part of my answer, (Exhibit A.) Question. What, in your opinion, is the effect of free trade in western Kentucky and Tennessee?
