Gordon C. Rhea 
Battles for Spotsylvania Court House and the Road to Yellow Tavern, May 7-12, 1864 [PDF ebook] 

The second volume in Gordon C. Rhea’s peerless five-book series on the Civil War’s 1864 Overland Campaign abounds with Rhea’s signature detail, innovative analysis, and riveting prose. Here Rhea examines the maneuvers and battles from May 7, 1864, when Grant left the Wilderness, through May 12, when his attempt to break Lee’s line by frontal assault reached a chilling climax at what is now called the Bloody Angle. Drawing exhaustively upon previously untapped materials, Rhea challenges conventional wisdom about this violent clash of titans to construct the ultimate account of Grant and Lee at Spotsylvania.
