“Local commanders went to bizarre lengths to prevent mistakes in identification during the early stages of the war. Realizing that many of the Federal troops wore gray while his own 33rd Virginia wore blue, "Stonewall" Jackson issued an order before the 1st Battle of Manassas (Bull Run) directing his men to identify themselves by tying strips of white cloth around their arms or hats. So as to make absolutely sure that no mistakes were made, his men were further directed to strike their left breasts with their right hands while simultaneously shouting "Our homes!" immediately they encountered an unknown unit. According to one disgruntled soldier, who presumably declined to take part in this somewhat lunatic theater, the commanders had "failed to tell us that while we were going through this Masonic performance we [were thus giving] the other fellow an opportunity to blow our brains out, if we had any." (page 48)”
