(April 19, 2006)--An informal memorial service may be held Wednesday at the site of the Branch Davidian compound to mark the 13th anniversary of the fire that killed almost 80 Davidians and ended the 51-day standoff with federal agents, but survivors don’t plan to attend this year, according to the Mt. Carmel Survivors Newsletter.

Fire survivor Clive Doyle wrote that he had hoped the memorial service this year would include some of the Davidians who were released from prison late last year, but said the former prisoners would not be allowed to attend.

“The survivors in this area will observe the day and get together somewhere off the property,” Doyle wrote.

Doyle was one of the handful of Davidians who escaped from the burning building on April 19, 1993.

The standoff at Mount Carmel started on Feb. 28, 1993 after Bureau of Alcohol Tobacco and Firearms agents launched a massive raid on the compound outside of Waco.

The raid left four agents and six Davidians dead.

The shootout stunned the ATF. The FBI moved quickly to take over operations and was in charge during the 51-day standoff that captured the attention of the world.

At one point, there were as many as 1,000 media representatives assembled along a rural McLennan County Farm to Market Road in an area that became known as Satellite City.

Analysts later said the intense media scrutiny of the government's handling of the standoff may have contributed to the FBI’s decision to use tear gas in an attempt to break the impasse.

FBI agents in armored vehicles pumped tear gas into the compound in an assault that began early in the morning on April 19, 1993.

Just after noon, fingers of flame began to shoot from one end of the compound.

A strong wind fanned the flames, which quickly engulfed the poorly constructed wood frame building.

As many as 80 died in the fire, including women and children.

Officials later admitted that pyrotechnic teargas devices were also used in the assault, but the government continues to maintain that the Davidians set the fire themselves.

Critics, however, include the producers of an Academy Award-nominated Documentary, 'Waco:the Rules of Engagement," challenge the official account.

Eleven surviving Branch Davidians were later tried in federal court in the deaths of the four ATF agents who died in the raid.

All were acquitted of murder, but four were convicted of the lesser offense of voluntary manslaughter.

Several have since been released to halfway houses.
