A vandal or vandals damaged several Union monuments at Gettysburg National Military Park in early January, and among the damaged monuments is one from Maine.
The park administration revealed January 9 on Facebook that the monuments “were recently defaced with oil-based substances.” The damaged monuments included the right-flank marker for the 6th Maine Battery; the monument for Pennsylvania Independent Batteries C & F; the Pennsylvania Memorial; and the left-flank marker for the 111th New York Infantry Regiment.

Except for the Pennsylvania Memorial, the vandal(s) daubed the oil-based substance low on the marker or monument and let the substance run down the granite. In a National Park Service photo, the 6th Maine Battery’s flank marker shows two distinct stains, and a third stain apparently mars a corner.
The vandal(s) extensively damaged the Pennsylvania Memorial (the largest park monument) by daubing the oil-based substances more than a dozen times around bronze panels inscribed with the names of Pennsylvania soldiers who fought at Gettysburg.
“While possibly intended as symbolic or ritualistic, the damage is real and lasting,” the National Park Service indicated on Facebook. “Porous stone absorbs oil deeply, making stains nearly impossible to remove. Restoration takes months and costs taxpayers thousands of dollars per monument.

“These memorials honor brave soldiers—many of whom died on the very ground where these markers now stand” the NPS stated. “Adding oil does not honor their memory. It desecrates it. Help us protect this hallowed ground. If you witness any suspicious activity, report it to park staff immediately.”
So what a flank marker was permanently stained with “oil-like substances”? you might ask. It’s what that flank marker stands for: the heroism that brave Mainers displayed at Gettysburg 162½ years ago.
Read on.
After William Barksdale’s Mississippians shattered the Peach Orchard salient and flanked Andrew A. Humphreys’ 2nd Division at Gettysburg on Thursday, July 2, 1863, Lt. Col. Freeman McGilvery of Searsport found an undefended 1,500-yard gap in the Union lines on Cemetery Ridge between Little Round Top and II Corps’ left flank. He needed time to “find some infantry or … collect and place some batteries” to fill the gaping hole.
Fill it with artillery batteries McGilvery did indeed do. Commanded by 1st Lt. Edwin B. Dow, the 6th Maine Battery numbered 103 men and ninety horses and belonged to the 4th Volunteer Brigade (Capt. Robert H. Fitzhugh), Artillery Reserve. At 6 p.m. that Thursday, Brig. Gen. Robert O. Tyler (the reserve’s commander) ordered Dow to join McGilvery.
The 6th Maine gunners dueled with “two batteries of the enemy, situated some one thousand yards in my front,” Dow reported. He soon spotted “a battle line of the enemy” (the Mississippians) pushing through the thickets along Plum Run “about six hundred yards distant, evidently” intending to cross over Cemetery Ridge and capture the Taneytown Road, “to my rear.
“I immediately opened upon them with spherical case and canister, and, assisted by a section of Captain Phillips’ (5th Mass.) battery, drove them back into the woods,” Dow reported.

“After repairing damages and getting a new supply of ammunition” on Friday, the 6th Maine Battery moved into position [on lower Cemetery Ridge] “between the 2nd Conn. battery and Ames’ (1st N.Y.) battery,” he reported.
As Pickett’s Charge developed that afternoon, “a light 12-pounder battery of four guns ran out some four or five hundred yards in front of the enemy’s lines, so as to enfilade the batteries on our right,” Dow reported. “We opened with solid shot and shell upon this battery, and succeeded in dismounting one gun, disabling the second, and compelled the battery to leave the field minus one caisson and several horses.”
The 6th Maine Battery’s survivors later erected a monument where their battery deployed on Cemetery Ridge on Friday morning, July 3, 1863. The flank markers stand to the left and right, and it’s the right-flank marker that a vandal(s) marred this month.
