Colonel Joshua Lawrence Chamberlain of the 20th Maine, who so valiantly defended Little Round Top at Gettysburg on July 2, 1863, was in command of the Union troops assembled in formation to observe and accept the stacking of arms. In deference to the officers of Lee's army, Chamberlain lowered his sword in an officer's salute as each ranking member of his former enemy passed by. Leading the parade of surrender were the surviving members of the Stonewall Brigade. Appendix
