(B) Union
EXPLANATIONS BELOW
Concept note-1: -The rebel yell was a battle cry used by Confederate soldiers during the American Civil War. Confederate soldiers used the yell when charging to intimidate the enemy and boost their own morale, although the yell had many other uses.
Concept note-2: -Confederate States of America, also called Confederacy, in the American Civil War, the government of 11 Southern states that seceded from the Union in 1860–61, carrying on all the affairs of a separate government and conducting a major war until defeated in the spring of 1865.
Concept note-3: -The rebel yell, the Confederate soldiers’ battle cry, is a sound we all know from westerns, in which it translates as a yee-haw. The Rebel yell was immortalized in the novel “Gone with the Wind” and in songs by Eminem and Billy Idol, who made it sound more like a yaaaaw.
Concept note-4: -The Northerners were called “Yankees” and the Southerners, “Rebels.” Sometimes these nicknames were shortened even further to “Yanks” and “Rebs.” At the beginning of the war, each soldier wore whatever uniform he had from his state’s militia, so soldiers were wearing uniforms that didn’t match.
Concept note-5: -Indian warriors often let out a loud war cry as they approached an enemy, possibly to create confusion or intimidation. It is possible Confederate rebels adopted this practice in order to create the impression of a much larger invasion force. “Rebel Yell” was the battle cry of Confederate troops during the Civil War.
