The Massacre at the Wedding Party was an attack on members of the United States Armed Forces by HYDRA by the use of a chemical weapon based upon the Obelisk in the champagne offered to the wedding guests.
He assigned one of his top scientists, Doctor Lingenfelter, with finding a way to replicate the Obelisk's effect. WIth much work, Lingenfelter created a chemical weapon based on the Obelisk's effects and were ready to test their creation.
- "Somebody help! Somebody help us!"
HYDRA decided to test their weapon at the wedding of Peter and Mariah Leitner. The wedding was attended by many of Peter's colleagues from the Navy. As Peter's best friend Schneider was giving his toast to the couple, the wait staff started to serve champagne to the guests and would not allow them any other drink.
After the toast, the guests who drank the champagne started to petrify and died. Some of the wedding guests suffered no effects while others had to be hospitalized.
Only a total of nine wedding guests died from drinking the poisoned champagne, which did not please Daniel Whitehall. He summoned his top scientists to discuss solutions to solving the problem of fully recreating the Obelisk's effect.
