While the 1862 Maryland Campaign has been extensively studied, a comprehensive treatment of the part played by each unit has been ignored. The Brigades of Antietam fills this void by presenting a complete account of each major unit, providing a fresh perspective of the campaign.

Using the words of enlisted men and officers, the book weaves a fascinating narrative of the role played by every unit (112 entries) from the time it began its march toward Sharpsburg to the final action at Shepherdstown. Organized by order of battle, each unit is covered in complete and exhaustive detail: where it fought, its commander, what constituted the unit, and how it performed in the campaign. Innovative in its approach and comprehensive in its coverage, The Brigades of Antietam is certain to be a classic and indispensable reference for the Maryland Campaign for years to come.

The book has been written by a collaboration of over 15 Antietam Battlefield Guides, Rangers, and seasoned Antietam volunteers. Bradley Gottfried, the author of The Brigades of Gettysburg, serves as the volume's editor.
