The fourth and, for now, final volume in Rhea's Overland Campaign series. This book covers the disengagement of Grant at North Anna, his crossing of the Pamunkey, the subsequent battles at Totopotomy Creek aka Bethesda Church (and various cavalry engagements like Haw's Shop and Ashland), and culminates with the main fighting at Cold Harbor. The famous assault on the morning of June 3rd is only about 40 pages out of nearly 400. As with the rest of the series there are good maps, an order of battle, and copious citations.
If you liked the first three books in this series then you'll like the fourth about the same. Published over the span of nearly a decade, this series is pretty consistent in tone and quality. This is probably the most important book in the series as it debunks many of the myths and corrects the common misunderstandings related to Cold Harbor. If you read only one book in this series, read this one.
I read the entire series consecutively which I think was mostly a good decision. It took me a little over a month.
A reoccurring theme in this series, especially this book, is the dysfunction of the Union upper command. A good full-length book could probably be written solely on command mistakes by Grant, Meade, and the corp commanders (Hancock, Warren, Sedgwick, Wright, Burnside, Smith, and Sheridan) which could impart valuable leadership lessons to everyone - generals, politicians, coaches, managers.
I'm told that the long-awaited fifth entry in this series, "Crossing the James", should finally be finished this year. It will presumably cover the rest of the fighting at Cold Harbor (June 4-12), Sheridan's Second Raid including Trevilian Station (June 11-12), and the shift of fighting to Petersburg (June 12-16). I'll be looking forward to it.
