Maj. Gen. Oliver O. Howard made a wise choice by picking the Josiah Wallis house for his headquarters during the Union advance on Kennesaw Mountain in Georgia. Rising near the circa 1853 dwelling is Harriston Hill, which was a perfect spot for a signal station because of its sweeping view of the valley leading to the Confederate lines atop the mountain.

The Wallis House, which served as a field hospital for both sides in June 1864, survives today. though it is in pretty rough condition. Harriston Hill, also known as Signal Hill, includes remnants of Confederate earthworks. Now part of Kennesaw Mountain National Battlefield Park, the two sites – separated by a subdivision -- await new use. The park says they can add a largely missing element: interpreting to visitors the Federal strategy at the Battle of Kennesaw Mountain.

There’s a lot of work being conducted before that goal is accomplished.

A master of architecture candidate at Georgia Tech in Atlanta has used LiDar (remote sensing technology) and a drone to create a model of the Wallis House for the National Park Service, which operates the park. He is wrapping up drawings for use in a historic structure report (HSR) that will be completed by the park next spring and used as a launching point on recommendations for use of the properties.

“Any time you have a chance to get to know a building is exciting, to understand it’s story a little more,” said Danielle Willkens, an associate professor of architecture at Georgia Tech. “You are on hallowed ground and that is palpable. There is another level of responsibility attached to the site.”

Willkens and student Thomas Bordeaux have been working with Suzanne Roche, the park’s first archaeologist. She told the Picket officials would like to see the two-bedroom Wallis house available to park visitors at some point, but it will require repairs and upgrades.

“Everyone is excited about having this house,” Roche said during a recent phone call. “They (park rangers) have been incorporating some interpretive information in their talks.”

It took years to protect and transfer site to park service

The Georgia Tech survey and a November 2021 NPS cultural landscape report on the Wallis farm and Signal Hill have brought new energy to the site, which has largely been out of the headlines in recent years.

The Wallis house was in “imminent danger” of being demolished, according to an NPS official who provided a statement to Congress in June 2010 in support of enlarging the park to include the sites. A developer had purchased 27 acres, including Harriston Hill and the Wallis homestead, in 2002, according to the official. 

Charlie Crawford, president emeritus of the Georgia Battlefields Association, recalls arguing against a rezoning for much of Signal Hill. “Although the Wallis house parcel was not part of the rezoning application, I said that the house and Signal Hill were both parts of a whole, both contributing to the site’s significant history.”

Working with the Cobb Land Trust, the Cobb County government acquired seven acres from the developer, including the farm and hill. About 43 homes are in the subdivision.

The land was donated to the federal park years later, in 2019, after Congress finally permitted expansion of the boundaries. (At left, entrance to the subdivision, Picket photo). The Covid crisis slowed action in 2020.

“I certainly agree this has been a long struggle,” Crawford told the Picket in an email.

“The inherent problem is making the building safe to visit (and up to code on electric, plumbing, HVAC) while still restoring its historical appearance.”

The house is off-limits, but that may change one day

Today, the setting is hardly bucolic. Cars whizz by on two busy highways – Burnt Hickory Road and Ernest W. Barrett Parkway – and the 41-home subdivision separates the Wallis house and Signal Hill. The park has no trespassing signs around the house, which is largely obscured by trees and vegetation. It allows no visitors to the property, citing safety and security concerns. Walking along Burnt Hickory is not recommended.

The 2021 cultural landscape report details ways to interpret the sites. At Signal Hill, some of the trees could be thinned so that visitors could get a view of Big and Little Kennesaw mountains. A trail to the entrenchments, which need to be stabilized, and other features could be built, along with interpretive markers. The Wallis farm could feature an outdoor education area, parking, restroom and signs.

The clash at Kennesaw Mountain was a costly, but brief setback during the Federal advance on Atlanta. Maj. Gen. William T. Sherman, commander of Union forces, was at the Wallis house during the Battle of Kolb’s Farm to the south.

Park and local officials are hoping the home can tell several stories, possibly featuring an exhibit on the role of African-American soldiers and civilians during the Civil War.

“General Howard is an important historical figure because of his successful leadership on the battlefield and his post-Civil War support of former slaves as head of the Freedmen's Bureau and founder of Howard University,” says the NPS.

His grandpa got tired of relic collectors

The Wallis house has been vacant for more than two decades. The site includes the home, original well and remains of two chicken coops and a smokehouse.

Commentary on a Historical Marker Database page about the dwelling includes a description by a Georgia man who said his grandfather acquired the land in the 1940s or 1950s.

“At the time of the purchase there were still doors inside the home with damage from a small skirmish fought on the property and within the home itself. Many floor boards were missing, and the house was in a general state of disrepair,” wrote Martin Jordan.

“It was not uncommon at all during the ‘60s and on for my grandfather to have to chase off relic seekers from the property surrounding the house, which was lined with trenches and earthworks,” Jordan added.

They don't build 'em like they used to

Willkens, the Georgia Tech professor, said the project has provided an ideal way for students to engage in preservation work. Bordeaux spent several days scanning the site, which was “very difficult” because of tree cover. The lack of other historic buildings nearby provided challenges on context.

Willkens (right) describes the house as a standard vernacular cottage, though its construction is a bit of a mystery. She thought at first it may have been a gable and saltbox style, but that is not the case. “It has some atypical arrangements.”

For some reason, the builders did not remove a massive tree stump before construction, she said.

The team took paint samples, ascertaining the original colors and is working with experts at the Smithsonian Institution to learn more about wood used in the dilapidated building.

“That house was probably built a lot better than something built five years ago,” said Willkens. “They have old growth trees, some additional redundancy in the structure.”

Postwar additions include a kitchen, laundry room, bathroom and back porch. Roche said no decision has been made about their fate, though the 2021 report suggests removing modern features.

The park would not provide photos of the home’s interior or Georgia Tech’s model and drawings, saying it wants to be careful in disseminating information and to safeguard the integrity of the site. Roche would not speak to the condition of the house. “You can walk inside it.”

The archaeologist and Willkens believe the structure can be saved.

Next steps in making the idea a reality

As stated earlier, the effort to save the house, give it permanent protection and have it help tell the story of the Atlanta Campaign is a long one.

Cobb County, just northwest of Atlanta, for years saw an incredible housing boom and development. While that was a boon for newcomers, preservationists and historians decried the loss of Civil War sites or land to development.

Now there’s an opportunity to offer something new in the telling of the battle.

“We are excited things are going on at the house,” said Roche. NPS historians visited the site just last week.

Much remains to be done. An engineer will need to study the feasibility of making repairs and restoring the Wallis house to its wartime appearance.

And officials will need to consider the cost of the project, its risks (concerns about vandalism) and rewards (enhanced interpretation). Major improvements on both sites could run into the millions of dollars. One feature now in place is a parking lot at the entrance of the subdivision allowing access to Signal Hill.

All of this will go in to the historic structure report (HSR), which is an involved process involving a lot of back and forth. “When we receive the recommendations from the HSR on how to proceed with either rehabilitation or restoration of the house, we will release the plans to the public for comment,” said Roche.

The archaeologist said acquiring such a historical treasure this many years later is not common, “which is why it is exciting.”

“We are really excited about hopefully being able to interpret this to the public,” said Roche.
