Lieutenant McDonald, of General Reynolds’ staff, with one company of the Thirteenth Indiana, formed the line of battle, placing the Twenty-fifth Ohio on his left, part of the Thirteenth Indiana on their left, and part of the Thirty-second Ohio on their left. The enemy immediately advanced to attack the Federal troops, but after a few rounds retreated in great confusion, leaving their dead and wounded. Colonel Moody’s division not appearing to attack the enemy on the left, the rebels seeing the inferior force opposed to them, were again encouraged to advance toward their assailants, which they did with a far superior force, pouring in their fire with vigor. Some of the Federals now commenced falling to the rear, all along the line; but Captains Charlesworth and Crowe, of the Twenty-fifth Ohio, Lieutenant McDonald, Captains Myers and Newland, of the Thirteenth Indiana, and Hamilton, of the Thirty-second Ohio, rallied them, and brought them into line in a few moments. The enemy again fell back and attempted to turn their right flank, but was immediately met and repulsed. The fortunes of the day appeared to alternate between the respective armies for three hours, the Federals holding out bravely against the superior numbers of the enemy, who were enabled to concentrate their entire army of two thousand men and four or five pieces of artillery against this comparatively small force. Colonel Moody’s force not having then been heard from, Colonel Jones, who had charge of the division now in action, after exhausting his ammunition, withdrew his men from the field. Almost at this juncture, Colonel Moody’s command, which had been detained by obstructions placed in the road over which they were compelled to pass, arrived, and attacked the enemy vigorously on his left, and in turn maintained an obstinate contest, unaided, against the entire rebel command, which they did with much courage and skill, until three o’clock, P. M., when they too were compelled to retire before the superior force of their opponents. Though thwarted in his plan of attack by the unexpected obstructions which Colonel Moody’s division had to encounter, General Milroy was far from being disconcerted by the result. The men had evinced a high order of courage, and the divisions had alternately maintained an obstinate fight against an army of nearly three times their number. The official report of the casualties on the Federal side gives the number of killed, twenty; wounded, one hundred and seven; missing, ten. The rebel loss is acknowledged by the Richmond _Enquirer_ to have been about the same. BATTLE AT MUNFORDSVILLE, KY. DECEMBER 17, 1861.
