Mort Kunstler, LaGrange vs. LaGrange, 2015.

The Atlanta-Constitution reports that the 87-year-old Kunstler’s last painting honors the female militia that save a small Georgia town in 1865.

For his final major painting before retiring, famed history artist Mort Künstler selected a fairly obscure Civil War event that occurred 150 years ago in LaGrange.

And, in the town a little more than an hour southwest of downtown Atlanta, the Troup County Historical Society will celebrate both the artist and the subject of his painting, the all-female Nancy Hart Militia, with a benefit event on Friday, April 17.

Guest of honor Künstler, a resident of Oyster Bay, N.Y., will unveil the painting, “LaGrange vs. LaGrange,” and sign canvas-printed reproductions.

The tribute marks the 150th anniversary of the day when the arms-toting Nancy Harts marched to the edge of town to meet invading Union troops, led by the ironically named Wisconsin Cavalry commander Col. Oscar LaGrange. The face-off occurred about a week after the Appomattox surrender, but before word had traveled to the town. LaGrange pledged that if the women would put down their guns, he would not burn their houses.

“The Nancy Harts story is unique not just to LaGrange, but also to the United States,” Troup County Historical Society President Jake Jones said. “ The charming town we enjoy today would not be the same if not for the bravery of these women.”
