Buell, after having sent some of his divisions as far east into the mountains as Jasper, Altamont, and McMinnville, with no results, moved his army to Nashville, thence with the reinforcements from Grant (two divisions), leaving two divisions and some detachments under Thomas to hold that city, through Tyree Springs and Franklin to Bowling Green, Kentucky, the advance arriving there September 11th.(16) Bragg was then at Glasgow. General James R. Chalmers and Colonel Scott, each with a brigade, the former of infantry, the other of cavalry, attacked, and Chalmers' brigade assaulted Wilder's position September 14th. The assault was repelled with much slaughter, Chalmers' loss being 3 officers and 32 men killed and 28 officers and 225 men wounded.(17) Chalmers then retired to Cave City, but returned with Bragg's main army on the 16th. Bragg having his army up, and Polk's corps north of Munfordville and Hardee's south of the river, opened negotiations for the surrender of the place. Being completely surrounded, with heavy batteries on all sides, Wilder capitulated, including 4133 officers and men. Chalmers was designated to take possession of the surrendered works on the morning of the 17th. Had Buell marched promptly on Munfordville from Bowling Green he would have found Bragg with one half of his army south of Green River and Polk with the other half north of it, and Wilder still holding a position on the river between the two. Bragg, after the surrender, concentrated his army south of Green River opposite Munfordville along a low crest of hills. He had not yet formed a junction with Kirby Smith, and his force then in position probably did not much exceed 20,000.(18) The position had no special advantages, was well known to many of Buell's officers, and should have been to Buell himself. In case of defeat, Bragg's army must have been lost and Kirby Smith's left to the same fate. Green River, passable in few places in Bragg's rear and to the north, would have rendered retreat impossible for a defeated army, and, besides, Bragg had no base north to retreat to. The situation was well understood in our army, except by Buell, who seemed to fear a junction with Kirby Smith had been formed, though Wilder (just paroled) and others of his officers on the day of the surrender informed Buell that no junction had been made. Wilder, however, had an exaggerated opinion of Bragg's strength at Munfordville. The junction of the two Confederate armies did not take place until October 9th, at Harrodsburg, the day succeeding the battle of Perryville.(19)
