Keeping Up With 'The Long Road Home' - Episode 4: 'In the Valley of Death'

We're in week number 3 of the National Geographic Channel's new 8-part event series "The  Long Road Home" and we've got a preview clip from tonight's episode titled "In the Valley of Death." Based on ABC News journalist Martha Raddatz’s best-selling book, the dramatic series chronicles April 4, 2004, the day that is known as the Iraq War’s “Black Sunday.” The First Cavalry Division from Fort Hood, Texas, was ambushed in Sadr City, Baghdad. The series follows the men in action and the reactions of their families back home in Texas.

In tonight's episode 4 (we got two episodes on premiere night, so the math is correct), rescue teams 1 and 2, led by Cpt. Troy Denomy (Jason Ritter) and Lt. Col. Gary Volesky (Michael Kelly), have been released to reach the troops who are stranded on the roof. They come heavily under fire but manage to evacuate the wounded and then regroup for another rescue attempt.

In the clip below, Lt. Shane Aguero (E. J. Bonilla) and his men brace for contact as they wait for the rescue vehicles to make their way to them. Sgt. Eric Bourquin (Jon Beavers) realizes that they weren’t al Sadr’s real target.

"The Long Road Home" airs on the NatGeo Channel on Tuesdays at 10pm/9pm CT.

Check out our coverage from the premiere at Fort Hood.
