Historian Bruce Catton was to the Civil War in the 1960's what Stephen Ambrose was to World War II in the 1990's and generally what Douglas Brinkley is today. As posted below he gave me my first real introduction to the American Civil War during the Civil War Centennial in the 1960's. This is from wikipedia:
Charles Bruce Catton (October 9, 1899 – August 28, 1978) was an American journalist and notable historian of the American Civil War. He won a Pulitzer Prize for history in 1954 for A Stillness at Appomattox, his study of the final campaign of the war in Virginia.
Catton was known as a narrative historian who specialized in popular histories that emphasized the colorful characters and vignettes of history, in addition to the simple dates, facts, and analyses. His works, although well researched and supported by footnotes, were generally not presented in a rigorous academic style. In the long line of Civil War historians, Catton is arguably the most prolific and popular of all, with Shelby Foote his only conceivable rival. Oliver Jensen, who succeeded him as editor of American Heritage magazine, wrote: "There is a near-magic power of imagination in Catton's work that seemed to project him physically into the battlefields, along the dusty roads and to the campfires of another age
Catton wrote many books on the Civil War but these three are my favorate:
The Centennial of the Civil War was memorialized from 1961 to 1965 and the publication of Bruce Catton's trilogy highlighted this era. Unlike his previous trilogy, these books focused not only on military topics, but on social, economic, and political topics as well.
The Coming Fury (1961) — Explores the causes and events leading to the start of the war, culminating in its first major combat, the First Battle of Bull Run.
Terrible Swift Sword (1963) — Both sides mobilize for a massive war effort and the story continues through 1862, ending with the Battle of Fredericksburg.
Never Call Retreat (1965) — The war continues through Vicksburg, Gettysburg, and the bloody struggles of 1864 and 1865 before the final surrender.
