In this engagement, the National loss was very much less than that of the rebels, notwithstanding the latter had so far outnumbered the former. On the 20th, a skirmish occurred between a Union force, part of Major-General Reynolds’s division, Colonel Wilder’s mounted brigade, and a cavalry force under Colonel Minty, and the enemy, who were stationed at a place called McMinnsville. The rebels formed a line, and charged upon the Unionists as the latter approached the city, where they had been sent from Murfreesboro’, to scatter any Confederate force which might be found at McMinnsville. The National troops encountered the rebel line, breaking through it at once, and drove the whole force, consisting of seven hundred men, from the town. Many men were taken prisoners by this Union force, and much destruction of rebel property accomplished. On the 29th, a small body of Union men, under Colonel Watkins, captured one of the enemy’s camps, taking prisoners one hundred and thirty-eight men. COLONEL STREIGHT’S EXPEDITION INTO GEORGIA. MAY 3, 1863. About the 20th of April, an expedition was fitted out to proceed into Northern Georgia, in charge of Colonel A. D. Streight, under whose command was placed the Fifty-first Indiana and Eightieth Illinois, together with portions of two Ohio regiments. Colonel Streight was officially notified that the chief object of his expedition was to push into Western Georgia, and cut the railroads which supplied the rebel army, by way of Chattanooga; and that in pursuance of this plan, he was not to allow incidental schemes, however promising as to results, to involve him in such delays, as would endanger his safe return. In order in deceive the enemy, he was to march long enough in company with the army of General Dodge, to give rise to the belief that he was a part of the expedition of the latter. He was further commanded to refrain from pillage and marauding, but to destroy all depots of supplies for the rebel army, all manufactories of guns, ammunition, equipment, and clothing for their use, which could be done without endangering their return. In obedience to these instructions, Colonel Streight embarked his soldiers from Nashville, and landed near Fort Donelson. From there he crossed the country to the Tennessee river, thence proceeded to Eastport, and conjointly with the forces of General Dodge, at the time marching upon Tuscumbia, gave battle to the Confederate troops, and defeated them with considerable loss.
