Alfred Moore Waddell was a Democratic Congressman and later had became the mayor of Wilmington, NC. He was a former Confederate officer so he was already against the black citizens voting in the election. This man, led 500. white men to the headquarters were Mr. Manly worked, and broke in, and started a fire.
After the Democrats took control of Wilmington, they put out a law, called the "Grandfather Clause". The Grandfather Clause is a law stating that you could not vote, unless your grandfather voted before 1864. They used this law for another way to prevent black citizens from voting in the south, or in any other elections.
