This clip depicts the Battle of Little Round Top during the Civil War. With his men out of ammunition, Union Colonel Chamberlain orders his forces to bayonet charge down the hill, resulting in a favorable outcome for the Union.
Colonel Chamberlain delivers a speech to a large group of men to redevote them to the cause of the Civil War. He explains that they are fighting for social justice: to set other men free rather than conquer land or loot. He desperately needs them to join his Northern Maine regiment for the battle, which became the turning point of the war and ultimately supported the outcome for the North.
