I finished this book this past Saturday. It's part of the publisher's (Westholme Publishing) Small Battles series, which focuses on less-well-known battles in the American Revolution.
Jack Buchanan is the author, and he's an absolute gem. He's one of the leading experts on the Southern Campaign (battles in the south during the American Revolution between 1779 - 1781). In addition, he has a great sense of humor, which he slips into the book periodically, without detracting from the historical information.
He makes a compelling argument that the Battle of Musgove's Mill was one of the pivotal battles in the South. It was fought a few days after the 2nd army sent to the South were absolutely routed at Camden, SC. (The 1st army had been forced to surrender at Charleston, after the civilian leadership had beseeched (and convinced) Gen. Benjamin Lincoln to not abandon the city as the British tightened their siege of the city.)
For the patriots at Musgrove's Mill, a collection of Georgia, South Carolina, and North Carolina militia, under the leadership of colonels Elijah Clarke, James Williams, and Isaac Shelby, respectively, joined together. No Continental army regulars were involved. They took on a group of loyalist militia, and soundly defeated them. The casualty rate for the loyalists was comparable to that suffered by the British at Bunker Hill, yet hardly anyone knows of Musgrove's Mill, while most Americans are at least aware of Bunker Hill.
Buchanan's contention, which is very convincing, was that the rout of the loyalists at Musgrove's Mill lead to British Major Patrick Ferguson chasing the patriots (and the 70 prisoners they captured at Musgrove's Mill) into Western North Carolina. His actions there, most specifically his direct challenge to seek out and eliminate the fighters and the families of the North Carolina militia men, are what caused the militia to greatly increase their numbers, come down out of the mountains, chase Ferguson's forces (provincials, which were loyalists that served in the British army (mostly from NY and NJ; smaller numbers from PA), and then deliver the first large victory of the Southern Campaign for the patriots, at King's Mountain (where Major Ferguson of the British was killed, as well as Col. Williams of the South Carolina militia).
As the book focuses on one small battle, the book is pretty short. Between the information provided, as well as the humor added by the author, I highly recommend this book for those that would like to learn about an under appreciated aspect of the American Revolution.
