Greg Mertz

A published author, professional battlefield guide, and former employee of the National Park Service for 40 years

Meet Greg Mertz

Greg’s fascination with the American Civil War and National Parks grew out of annual visits his St. Louis area Boy Scout troop took to Shiloh National Military Park. After earning a bachelor’s degree in Recreation and Park Administration at the University of Missouri, he worked for four years at Gettysburg National Military Park and the Eisenhower National Historic Site. While at Gettysburg, he also earned a master’s in Public Administration from Shippensburg University.

Greg then transferred to Fredericksburg and Spotsylvania National Military Park where he worked for 36 years — 27 of them as the Supervisory Historian, managing the park’s visitor services and training hundreds of seasonal employees, interns, and volunteers in the art of interpretation.

His interests in public history and preservation include service in several organizations outside of his 40-year career with the National Park Service. Greg is the founding president and a current board member of the Rappahannock Valley Civil War Round Table and has given numerous talks and tours to other Civil War Round Table groups.

He is currently the vice president of the Brandy Station Foundation and was on its board during the organization’s early days when the largest cavalry battle on the continent was threatened by an office park and a race track. Greg’s duties while working at the park, included training volunteers with Friends of Wilderness Battlefield, and his admiration for the group is reflected in his retirement thought service on their Board.

Published Civil War Author

In 2019, Greg authored the book Attack at Daylight and Whip Them: The Battle of Shiloh, April 6-7, 1862 in the Emerging Civil War series published by Savas Beatie. He has also written the feature article for four issues of Blue & Gray Magazine – a two-part treatment of the Battle of the Wilderness, and another pair of issues on the fighting in Spindle Field and Laurel Hill, and on Emory Upton’s attack – both portions of the Battle of Spotsylvania Courthouse.

Greg lives on the Peyton Farm portion of the Spotsylvania Court House battlefield with his wife, Diane, who he met on a Civil War tour of some West Virginia battlefields. He presents tours of Shiloh, Cedar Mountain, Fredericksburg, Kelly’s Ford, Chancellorsville, Brandy Station, Rappahannock Station, Mine Run, Wilderness, and Spotsylvania Court House.

Took a full day tour of Jacksons Valley Campaign a few weeks ago and it was outstanding. The tour guide was well prepared and provided an in-depth overview of the multiple battles that make up this campaign.


We are big Civil War buffs, and even after reading about the battles and previously visiting some of the battlefields, we STILL learned so much. Highly recommend this tour for anyone, it’s well worth it.


We would highly recommend taking as much of the tour as you can. I learned so much and appreciate how he explained each battle. My husband has always been very interested in the civil war and now I am too. Can’t wait to go on more tours.
