My work The Lion of Little Round Top, depicts Chamberlain at the second he begins to order Bayonets! for his famous charge.
On the extreme left end of the federal line, the 20th Maine had been ordered to hold its ground at all costs. After several charges by Confederates had been repulsed, the men from Maine were nearly out of ammunition. As the Confederates came in a final attack, Col. Joshua Chamberlain bellowed the order, “Bayonets!” His men fixed bayonets, and without ammunition, charged down the slope toward the Confederates.
Stunned by the ferocity of the 20th Maine’s assault, and exhausted by the day’s fighting, many of the Confederates surrendered. The Union line had held, and Little Round Top was secure.
The heroism of Joshua Chamberlain and the 20th Maine was featured in the historical novel The Killer Angels by Michael Shaara, which was published in 1974. The novel was the basis for the movie "Gettysburg," which appeared in 1993. Between the popular novel and the film, the story of Little Round Top has often appeared in the public mind as solely the story of the 20th Maine.
