by Roger D. Hunt
From the publisher:
Meticulously researched, Colonels in Blue compiles biographical sketches and photographs of the diverse group of men—mostly citizen-soldiers from a wide variety of backgrounds—who attained the rank of colonel in the Union Army and commanded regiments from the states of Pennsylvania, New Jersey, Maryland, Delaware, and the District of Columbia.
Roger D. Hunt is the author two previous Colonels in Blue books, one covering the New England states and the other covering New York state , and Brevet Brigadier Generals in Blue. He lives in Gettysburg, Pennsylvania.
The exact day of release for this October title is unknown. Amazon lists its release in August but both the publisher and B&N make this out to be an October release.
