Loring's division camped at Montevallo from April 9th until May 5th. Ordered to join the Army of Tennessee at Resaca, Scott's Brigade with the 12th Louisiana Infantry in the lead departed Montevallo on May 5th on the Alabama & Tennessee traveling through Talledega to Blue Mountain where the railroad ended. From Blue Mountain, they marched about 60 miles overland to Rome, Georgia covering the distance in three days and reaching Rome on the evening of May 9th. A spur of the Western & Atlantic Railroad ran from Rome to Resaca. The regiment was immediately placed aboard the cars and reached Resaca the next day, 10 MAY 1864. Departing Blue Mountain, Scott's Brigade consisted of the 9th Arkansas Infantry and the 55th and 57th Alabama Infantry regiments. The 27th and 35th Alabama Infantry regiments, which had been sent home from Demopolis on a recruiting furlough joined the brigade at Resaca on 12 MAY 1864. Scott's Brigade was the vanguard of General Polk's Army of Mississippi which became Polk's Corps in the Army of Tennessee.
I find the transportation story almost as fascinating as the fighting itself!! Thanks for asking!
