On the morning of August 1, 2009, he and a guide were in Tanzania, observing a group of elephants from 200 yards away, when an elephant charged Siebel's guide and then turned on Siebel, breaking several ribs, goring him in the left leg, and crushing the right. They radioed for help, but it was three hours before he received any medical treatment. He was flown to the Aga Khan University Hospital in Nairobi, where they cleaned his wounds and stabilized his leg. He was then flown back to the United States on a 20-hour FLIGHT with only 10-hours of morphine and 15 hours of fluids. He had lost half of his fluids and was put in the intensive care unit. He was moved to Stanford Hospital where, over the next six months, they performed 11 surgeries, fixed his ribs and shoulder, and saved his left leg.
In September 2010, a year after the attack, Siebel had undergone 16 surgeries and an Ilizarov apparatus external fixator to mend, lengthen, and reshape the tibia of his right leg. After enduring 19 reconstructive surgeries total over two and a half years, Siebel has now made a full recovery. In 2013, National Geographic included Siebel’s account in its TV series Dead or Alive: Trampled on Safari
