It was at Little Round Top that the Twentieth Maine, with Joshua Chamberlain in command, performed one of the miracles of the Civil War and saved the left flank of the Union battle line. Outnumbered two to one, their front doubled back to the shape of a horseshoe. And with ammunition gone, the men fixed bayonets, charged, and not only broke up the Confederate attack, but took four hundred prisoners.

At Appomattox, the Twentieth Maine was one of the regiments chosen to receive the surrender of General Lee’s infantry, and Joshua Chamberlain, the Bowdoin professor who had become a general, was appointed to command the Union troops at the ceremony.
