“Kreiser breathes new life into this most important of Union Army units. . . . A remarkably well-written and superbly researched account.” —David E. Long, author of The Jewel of Liberty: Abraham Lincoln’s Re-election and the End of Slavery Fair Oaks, the Seven Days, Antietam, Fredericksburg, Gettysburg, Cold Harbor, Petersburg—the list of significant battles fought by the Second Corps, Army of the Potomac, is a long and distinguished one. This absorbing history of the Second Corps follows the unit’s creation and rise to prominence, the battles that earned it a reputation for hard fighting, and the legacy its veterans sought to maintain in the years after the Civil War. More than an account of battles, Defeating Lee gets to the heart of what motivated these men, why they fought so hard, and how they sustained a spirited defense of cause and country long after the guns had fallen silent. “[An] excellent contribution to Civil War history shelves.” —Midwest Book Review “Lawrence Kreiser tells the Second Corps’ story with verve and attention to personal as well as bureaucratic details.” —Civil War Librarian
