In the early morning hours of March 4th, 2002, a reconnaissance team of US Navy SEALs became pinned down on the ridge dividing the Upper and Lower Shahikot valley in Afghanistan.
A Chinook helicopter with 21 men on a mission to rescue them was heading for the snowcapped peak of Takur Ghar when U.S. military officers in Bagram radioed them with a message not to land on the peak, because the mountaintop was under enemy control.
The rescue team never got the message. Just after daybreak, the Chinook took heavy enemy fire and it crash-landed on the peak. Three men were killed in the ensuing firefight.
