“To the Editors of the Missouri Republican: Gentlemen–I have this day discovered in your paper of the 22d ult. an account of the engagement between the men under my command and the hostile Sac and other Indians on the Rock River. Finding that statement altogether incorrect, I take the liberty to give an outline of the transaction, which I am compelled to do in the utmost haste. “On the 12th I received orders from His Excellency, John Reynolds, Commander-in-Chief, etc., to march immediately from Dixon’s Ferry to what is commonly known as Old Man’s Creek, about 30 miles distant, and coerce the said hostile Indians into subjection. We took up our march on the 13th, and on the 14th, at 2 o’clock, one of our spies discovered two Indians on our left. The Indians immediately fired on him, and undertook to make their escape by swimming Rock River; this, however, they did not succeed in; our spy brought his gun to bear on the forward one, who was tumbled into the river–the horse immediately turned his course and swam back, the surviving Indian being, from the unmanageable disposition of his horse, compelled to follow until he shared the fate of his companion. Both horses were brought in. We reached our camping ground on the north side of Old Man’s Creek about 6 o’clock, after having used every precaution to guard against being deceived by the Indians, having kept out the most experienced spies and a very strong guard front, rear and flank, during the day. Soon after our arrival we discovered a small party of men in our advance, supposed at this time to be a part of our front guard. Lieutenant Gridley being then mounted, passed up a ravine for the purpose of ascertaining. It was soon after, however, ascertained that our spies with the whole of our advance guard had come in. Captain Covell with a party detached, followed. On the approach of Lieutenant Gridley, while rising the bluff, the Indians faced and leveled their guns. When prudence directed a return, the Indians pursued and were met by Captain Covell at nearly the same moment, when the fire was exchanged without effect. The Indians retreated and were pursued. Three were killed and three taken, with a loss of one of our men (as supposed). Our men were all immediately formed and took their march in the direction of Sycamore Creek, five miles above. After marching about three miles an Indian appeared and made signs of peace. I was informed of the fact, and orders were given for a halt. Myself, together with most of the field and staff officers advanced with Captain Eads as interpreter. We were soon informed that the Indians would surrender in case they would be treated as prisoners of war. This was promised them, and they returned with the intelligence, after promising to meet us at a specified point. On arriving at that point, however, no Indians appeared to make the proposed treaty, which convinced us of
