“_Sir_: The brigade organized under your command is intended to operate against the rebel force threatening, and, indeed, actually committing depredations in Kentucky, through the valley of the Big Sandy. The actual force of the enemy, from the best information I can gather, does not probably exceed two thousand, or twenty-five hundred, though rumors place it as high as seven thousand. I can better ascertain the true state of the case when you get on the ground. “You are apprised of the condition of the troops under your command. Go first to Lexington and Paris, and place the Fortieth Ohio Regiment in such a position as will best give a moral support to the people in the counties on the route to Prestonburg and Piketon, and oppose any further advance of the enemy on the route. Then proceed with the least possible delay to the mouth of the Sandy, and move with the force in that vicinity up that river and drive the enemy back or cut him off. Having done that, Piketon will probably be in the best position for you to occupy to guard against future incursions. Artillery will be of little, if any, service to you in that country. If the enemy have any it will incumber and weaken rather than strengthen them. “Your supplies must mainly be taken up the river, and it ought to be done as soon as possible, while navigation is open. Purchase what you can in the country through which you operate. Send your requisitions to these head-quarters for funds and ordnance stores, and to the quartermasters and commissary at Cincinnati for other supplies. “The conversation I have had with you will suggest more details than can be given here. Report frequently on all matters concerning your command. Very respectfully, your obedient servant, “D. C. BUELL, “Brigadier-General commanding.” On receipt of these instructions, Garfield began instantly to carry them out. He telegraphed his forces at Catlettsburg to advance up the Big Sandy towards Paintville, Marshall’s advance post. This he did that no delay should be occasioned by his absence. He then visited Colonel Cranor’s regiment, and saw it well established at Paris. Returning thence, he proceeded to hasten after his own regiment, and reached Catlettsburg on the 20th of December. Here he stopped to forward supplies up the river to Louisa, an old half-decayed village of the Southern kind, where he learned that his men were waiting for him.
