Read the excerpt from “John Burns: The Unlikely Civil War Hero.” It wasn’t long before John came upon the 150th Pennsylvania Infantry. They were moving quickly toward the battlefront when John offered his services to Major Thomas Chamberlain, the first officer he saw. Although the major eyed him doubtfully, he directed John toward his commander, Colonel Langhorne Wister. As John made his way to the man in charge, many of the privates laughed at the old man’s getup: yellow vest, brass-buttoned blue coat, and silk hat. Even though the air was thick with tension over the coming fight, the men could not take John seriously. However, the soldiers would soon learn that the man who wore the unusual outfit was someone to respect.
