This year marks the 25th anniversary of the Waco siege, a 50-day conflict between the Branch Davidians and U.S. and Texas law enforcement agents.

The Davidians, a splinter group of the Seventh-day Adventist Church, had attracted the attention of law enforcement following allegations of polygamy, sexual abuse and possession of illegal weapons.

On February 28, ATF agents assembled to raid the facility. What followed was a fierce gun battle that resulted in the deaths of four agents and five Branch Davidians.

From that day until April 19, federal and state law enforcement agents were engaged with the Branch Davidians in a tense standoff. Despite weeks of negotiations, Koresh and his followers refused to budge from their compound.

Finally, on April 19, then-President Bill Clinton signed off on Attorney General Janet Reno and the FBI's recommendation to assault Mount Carmel.

The FBI bombarded the compound with numerous tear gas rounds in an attempt to flush the group out of the facility. During that time, there were reports of Branch Davidian members igniting fires around the building.

Eventually, those fires multiplied and engulfed the entire site. At the end of the day, 76 Branch Davidians died. Autopsy results showed some of the victims had been shot and stabbed, likely as a mercy killing or suicide attempt. FBI investigators said one of Koresh's aides shot and killed him.

The assault and its aftermath became one of the most controversial moments in American history, and would later serve as the impetus of the far deadlier Oklahoma City Bombing.
