Gettysburg Movie the best part – Battle of Little Round Top
The left flank consisted of the 358 men of the 20th Maine regiment and the 83rd Pennsylvania. Seeing the Confederates shifting around his flank, Chamberlain first stretched his line to the point where his men were in a single-file line, then ordered the southernmost half of his line to swing back during a lull following another Confederate charge. It was there that they “refused the line”—formed an angle to the main line in an attempt to prevent the Confederate flanking maneuver. Despite heavy losses, the 20th Maine held through two subsequent charges by the 15th Alabama and other Confederate regiments for a total of ninety minutes.
On the final charge, knowing that his men were out of ammunition, that his numbers were being depleted, and further knowing that another charge could not be repulsed, Chamberlain ordered a maneuver that was considered unusual for the day: He ordered his left flank, which had been pulled back, to advance with bayonets in a “right-wheel forward” maneuver. As soon as they were in line with the rest of the regiment, the remainder of the regiment charged, akin to a door swinging shut. This simultaneous frontal assault and flanking maneuver halted and captured a good portion of the 15th Alabama.
