Here is a little tidbit that I copied from a book published circa 1930--Ward's history of Coffee County : a story dealing with the past and present of Coffee County, beginning with the early settlers about the year 1800, discussing the Creek Indians and the pioneers, leading up to the creation of Coffee County in 1854, old families, old schools and churches, showing the conditions during the Civil War and ending up with the spirit of progress, which is evident in better schools, and a more intelligent civilization : showing that Coffee County in south Georgia is God's country and a good place to live in the year 1930.

I transcribed this from the page in the book.

Erwin Spivey, known by the Armies North and South as "Gordon's Bull" was in Company E. 26th, Georgia. Mr. Spivey had a tremendous voice, loud, wild and weird. He could squeal and yell and bellow like a bull and be heard for miles around. He trained his voice in such a way as to give it "Carrying Power." He was the talk of both armies. He belonged to Gordon's Bridage, which was a terror to the Northern Army. The Yankee Army could recognize the strange voice of Erwin Spivey and they knew that Gordon was after them. When the Yankees would hear him it is said that the soldiers would look at each other and say, "Boys, there is trouble ahead. Gordon's Brigade is on the move and Gordon's Bull is giving the alarm." It is said that many of the weak-kneed Yankees would break ranks and run for their lives when they heard the yell of "Gordon's Bull."
