author
A Civil War memoirist from East Tennessee, he is remembered for a firsthand account of escaping Confederate territory to reach Union lines. His short book offers a personal, on-the-ground view of loyalty, danger, and survival during the war.
Robert A. Ragan is known for Escape from East Tennessee to the Federal Lines: The History, Given as Nearly as Possible, published in Washington, D.C., in 1910. The Library of Congress lists it as a Civil War personal narrative and credits him as the author.
From the title and cataloging information, Ragan appears to have written from direct experience in East Tennessee during the Civil War, recounting a dangerous journey through a deeply divided region. His work stands out less as a polished literary memoir than as a compact eyewitness record of wartime movement, uncertainty, and Unionist feeling in Tennessee.
Reliable biographical details about his wider life are limited in the sources I could confirm here, so it is safest to remember him chiefly through this surviving memoir and the historical perspective it preserves.
