Gettysburg, Pennsylvania, was the site of a battle that turned the tide of America’s Civil War. One of the focal points of the conflict was a rocky knoll called Little Round Top where Colonel Joshua Lawrence Chamberlain and the men of the 20th Maine Infantry stood their ground. Had the Confederate troops gotten past Chamberlain’s men, some historians believe the Union army would have been surrounded—possibly leading to the loss of the war. The “20th Maine” was the last line of defense.
