About 15,000 people went to the ceremony. This included the governors of six of the 24 Union states. They were Andrew Gregg Curtin of Pennsylvania, Augustus Bradford of Maryland, Oliver P. Morton of Indiana, Horatio Seymour of New York, Joel Parker of New Jersey, and David Tod of Ohio. Canadian politician William McDougall came as Lincoln's guest. Historians do not agree about the exact place where the dedication ceremony was held inside the cemetery. Moving all the bodies to the graves in the cemetery was less than half complete on the day of the ceremony.
