The Last Patrol, Sebastian Junger’s third and final chapter in a trilogy of films about war and its devastating effects on soldiers, came to fruition after he and documentary photographer Tim Hetherington made plans to walk from Washington D.C. to New York City along railroad lines.
The trip would mimic the long patrols both men were accustomed to when covering the war in Afghanistan, on embeds with the U.S. military. The only difference being that they wouldn’t be shot at, wouldn’t have to run for cover, wouldn’t fall into an ambush.
Their trip never came to be. In April 2011, Hetherington was killed in Misrata, Libya, while covering the people’s uprising against their dictator, Muammar Gaddafi.
Hetherington’s death shocked an entire industry of journalists and photographers, and convinced some of them to give up on war, Junger included.
This year, Junger went on that “last patrol”, reigniting the plans he had made with his friend and colleague to walk along America’s railways. Accompanied by combat veterans Brendan O’Byrne, who appeared in Junger’s Restrepo, and Dave Roels, as well as Spanish photographer Guillermo Cervera, who witnessed Hetherington’s death, he walked from Washington D.C. to Philadelphia and to Pittsburgh.
Together, the four men, all war veterans in their own ways, discussed “why combat is so incredibly hard to give up,” they say. The resulting documentary, which chronicles their “last patrol” premieres on Monday, November 10 on HBO.
The Last Patrol by Sebastian Junger is available on HBO and HBO GO from November 10 at PM (CET).
