This modern study focuses solely on the cavalry of the Army of the Potomac and includes all major battles and commanders. Drawing heavily on primary sources, the author has consulted 50 manuscript collections pertaining to general officers of cavalry as well as the unpublished letters and diaries of 200 officers and enlisted men, representing almost every mounted unit in the Army of the Potomac.

“A mosaic of thousands of tiny pieces that, seen whole, amounts to a fascinating picture of what probably was the most important moment of the Civil War.” —Thomas E. Ricks, New York Times bestselling author of The Generals George Armstrong Custer is famous for his fatal defeat at the Little Bighorn in 1876, but Custer’s baptism of fire came during the Civil War. His true rise to prominence began at Gettysburg in 1863. On the eve of the Battle of Gettysburg, Custer received promotion to brigadier general and command—his first direct field command—of the Michigan Cavalry Brigade, the “Wolverines.” Custer did not disappoint his superiors, who promoted him in a search for more aggressive cavalry officers. At approximately noon on July 3, 1863, the melee that was East Cavalry Field at Gettysburg began. An hour or two into the battle, after many of his cavalrymen had been reduced to hand-to-hand infantry-style fighting, Custer ordered a charge of one of his regiments and led it into action himself, screaming one of the battle’s most famous lines: “Come on, you Wolverines!” Around three o’clock, the Confederates led by Stuart mounted a final charge, which mowed down Union cavalry—until it ran into Custer’s Wolverines, who stood firm, breaking the Confederates’ last attack. In a book combining two popular subjects, Tucker recounts the story of Custer at Gettysburg with verve, shows how the Custer legend was born on the fields of the war’s most famous battle, and offers eye-opening new perspectives on Gettysburg’s overlooked cavalry battle. “A thoughtful and challenging new look at the great assault at Gettysburg . . . Tucker is fresh and bold in his analysis and use of sources.” —William C. Davis, author of Crucible of Command

Cavalry operations during the Gettysburg campaign have been well covered, but never like this. Most cavalry treatments of the campaign and battle have focused on strategy, operations, and tactics and zoomed in on particular episodes: the Battle of Brandy Station in June 1863 (the largest cavalry engagement on American soil), Jeb Stuart’s controversial ride-for-glory that deprived Lee of important intelligence for days, Union cavalry general John Buford’s role in the start of the battle on July 1, and the cavalry battle involving not only Stuart but also George Armstrong Custer east of Gettysburg on July 3. Daniel Murphy’s book covers the grand sweep of cavalry in the Gettysburg campaign, from Lee’s crossing of the Rappahannock in early June 1863, through the epic three-day clash in Pennsylvania, to the conclusion of Lee’s retreat in July 1863. But more than that, in a book blending strategy and tactics and campaign narrative with deep research in primary sources and an equestrian’s sense for what it’s like to ride and manage horses, Daniel Murphy brings a horseman’s eye to the story of the campaign: how individual cavalrymen experienced the campaign from the saddle and how horses—with special needs for care and maintenance—were in fact weapons that helped shape battles. In this new narrative of Civil War cavalry, author Daniel Murphy gets into the saddle and explores what it was like to be a cavalryman during the Gettysburg campaign. Horse-soldiering was a unique way of doing battle, and Murphy gives it more justice and nuanced description than any author has yet given it.

The Fifth New York Cavalry was a volunteer regiment organized in response to the Union defeat at the Battle of Bull Run in July 1861. The citizen-cavalrymen who made up the regiment came from across New York State and from every walk of life. In the following four years the unit became, according to contemporary sources, one of the finest cavalry formations in the field. The regiment's history is told chronologically in the overall context of the Civil War and based upon primary sources, including official reports, diaries, letters and newspaper accounts. Wherever possible Fifth New York troopers speak to us directly, describing their experiences in the Shenandoah campaign of 1862, the epic encounter at Gettysburg, life in camp and on picket duty, the Wilderness in the spring of 1864 and again the Shenandoah in the fall of 1864.

This is the story of Lincoln's famous army of the Potomac during the early years of the Civil War, when it was under the command of General George B. McClellan.

Until its soldiers mustered out of service in mid-1864, the Pennsylvania Reserve Division was one of only a few one-state divisions in the Union army. Known as the Pennsylvania Reserves, or simply the Reserves, the division saw action in most of the major battles of the Civil War, including Mechanicsville, New Market Crossroads, Second Bull Run, Fredericksburg, Gettysburg, the Wilderness, and Spotsylvania Court House. This history chronicles the division's service from its organization in May 1861 through June 1864, when most of its soldiers reached the end of their service commitment. The book includes short biographical sketches, most with photographs, of the Reserves leadership. Throughout, excerpts from letters, journals, diaries, and books from more than 150 members of the Reserves provide a personal perspective on the action and reveal the human side of battle.
