The regiment famously associated with the defense of Little Round Top is the 20th Maine.

Under the leadership of Colonel Joshua Chamberlain, the 20th Maine Regiment was instrumental on July 2, 1863, during the Battle of Gettysburg. Stationed at the far left flank of the Union line, they endured numerous assaults from Confederate forces. Their unwavering defense, highlighted by Chamberlain’s daring bayonet charge when supplies were dwindling, was crucial in maintaining their position. This courageous act not only safeguarded the Union flank but also emerged as a powerful emblem of valor and strategic brilliance in the conflict.
