Read the paragraph. How was the 20th Maine Regiment so instrumental in winning the Battle of Gettysburg? Its members recognized the strategic importance of holding their position. Because they knew that the Confederates could win if they managed to break through the line, the regiment rebuffed three direct assaults. When the regiment ran out of ammunition before the third assault, they used bayonets and actually charged downhill. Because of their heroic action, the enemy surrendered, and the line was secure.
