From CNN, where you can read more on the story (including what measures the firefighters took to try to survive the blaze):

They were part of an elite squad who confronted wildfires up close, setting up barriers to stop the spreading destruction.

But the inferno blazing across central Arizona proved too much, even for the shelters the 19 firefighters carried as a last-ditch survival tool.

The firefighters were killed Sunday while fighting the Yarnell Hill fire, northwest of Phoenix. Among them was Eric Marsh, superintendent of the Granite Mountain Hotshots, according this father, John Marsh.

It was the deadliest day for firefighters since the 9/11 attacks. And it is the deadliest wildland fire since 1933, according to a list from the U.S. National Wildfire Coordinating Group. Twenty-five firefighters died when a blaze burned in light chaparral near Griffith Park, California.

“Our entire crew was lost,” Prescott Fire Chief Dan Fraijo told reporters Sunday night. “We just lost 19 of some of the finest people you’ll ever meet. Right now, we’re in crisis.”

The tragedy killed about 20% of the Prescott Fire Department. Fraijo said one member of the team was not with the other crew members and survived.
