LISBON FALLS – Charles W. Plummer, in the persona of Gen. Joshua L. Chamberlain, will address the Lisbon Historical Society at 7 p.m. Wednesday, Aug. 13, at the historical society’s archives, Enterprise Street.

Plummer will describe the heroic roles that Maine regiments played at the Battle of Gettysburg on July 1, 2 and 3, 1863, which resulted in the defeat of Gen. Robert E. Lee’s Army of Northern Virginia. It was this battle that proved to be an important turning point for the Union during the Civil War.

Volunteer infantry regiments from Maine that were actively engaged in the three-day battle were the 3rd, 4th, 5th, 6th, 7th, 16th, 17th, 19th and 20th; the 2nd, 5th and 6th Maine Batteries; the 2nd U.S. Sharpshooters; the 1st Maine Cavalry; and the 10th Maine Battalion.

As Gen. Chamberlain, who commanded the 20th Maine, Plummer will give a detailed account of the action in which these units were engaged, the casualties that each one suffered and the names and fates of the volunteers from Lisbon who were serving with some of the regiments.

His presentation will also include the showing of slides of the Gettysburg battlefield.

Plummer’s specialty as a living historian is portraying famous Civil War generals and other personalities. He has traveled throughout the country portraying such notable figures as Gen. Chamberlain, Gen. Robert E. Lee, Gen. Ulysses S. Grant, Gen. Stonewall Jackson, Gen. William T. Sherman and Gen. James Longstreet.

He has addressed the Lisbon Historical Society in the past as Abraham Lincoln’s vice president, Hannibal Hamlin, as President Theodore Roosevelt and as Lewis Ketchum, who was a log-driver on the Penobscot River.
