Statement of Brigadier-General Dandridge McRae. Searcy, November 1895

"When the Federal General Steele advanced upon Little Rock in September, 1863, I mas in command of an ifantry brigade of Arkansas troops in the Confederate States service at that point. Upon the capture of Little Rock by the Federals, they obtained possession of the Arkansas River valley. together with all of that portion of the state lying north of that river. This fact vas fully understood by the rank and file of the Arkansas troops, a large proportion of whom resided in that part of the state. They had anticipated that General Holmes mould make a stand at Little Rock and make an effort to retain possession of that place, and in such anticipation the ranks of the Arkansas regimente were unusually full. When the order to retreat mas made, and the army learned that the country in which mere their families was to be given up without an effort to retain it, it produced intense indignation, resulting in great demoralization, and the men in great numbers abandoned their colors and returned home. Comparatively few deserted to the Federals. Three of my regiments had been recruited in north Arkansas, and from the above cause my loss was great, much greater than it would have been had a battle been fought.

General Holmes retreated to Arkadelphia, where he halted his command. Reporting to him my losses, and that the men had not deserted to the enemy but had returned home, he directed me to consolidate the companies and reqiments of my command, and with the supernumerary officers left without a command, by reason of such consolidation, to proceed to northeast Arkansas, and to assume command over that portion of the state lying between White and Mississippi rivers, and collect and return to their commands all absentees found in that section."
