The second installment of Al Ovies’s trilogy encompasses a period jammed with tumultuous events for the cavalry on and off the battlefield and a significant change of command at the top.Once below the Potomac River, the Union troopers raced down the east side of the Blue Ridge Mountains but were unable to prevent General Lee’s wounded Army of Northern Virginia from reaching Culpeper. The balance of 1863 was a series of maneuvers, raids, and fighting that witnessed the near-destruction of the Michigan Cavalry Brigade at Buckland Mills and the indecisive and frustrating efforts of the Bristoe Station and Mine Run campaigns. Alfred Pleasonton’s controversial command of the mounted arm ended abruptly, only to be replaced by the more controversial Philip H. Sheridan, whose combustible personality intensified the animosity burning between George Custer and Wesley Merritt.Victory and glory followed the Cavalry Corps during the early days of the Overland Campaign, particularly at Yellow Tavern, where Rebel cavalier Jeb Stuart was mortally wounded. The spirited rivalry between Custer and Merritt took a turn for the worse and at Trevilian Station, the bitterness and rancor permeating their relationship broke into the open and made it into their official reports. Merritt’s elevation to temporary command of the 1st Cavalry Division cemented their rancor.The worsening relationship coincided with the darkening of the war. As the sieges of Richmond and Petersburg ground on and Confederate partisan operations intensified, Gen. U. S. Grant demanded Sheridan seek retribution, which prompted the cavalry leader to deliver his infamous edict to “eat out Virginia clear and clean as far as they go, so that crows flying over it for the balance of the season will have to carry their provender with them.” Much of this gritty task fell on the shoulders of his “boy generals.”This well-researched and meticulously detailed account of the increasingly dysfunctional relationship between Custer and Merritt follows the same entertaining style as Ovies’s first installment. will change the way Civil War enthusiasts understand and judge the actions of the Union’s bold riders.
