Al-Qaeda top leaders Osama bin Laden and Ayman al-Zawahiri escape from the Tora Bora battle north to a remote province in Afghanistan. In the years just after the Tora Bora battle, the conventional wisdom will be that bin Laden escapes across the nearby border into Pakistan. A 2006 book by Ron Suskind will be the first to publicly make the argument that bin Laden actually stays in Afghanistan and heads to even more remote regions north of Tora Bora, starting around December 15, 2001 (see December 15, 2001). After bin Laden is killed in May 2011 (see May 2, 2011), US officials will reveal that this ‘go north’ theory has become the new conventional wisdom. According to the Washington Post: “US interrogators later learned from Guantanamo detainees that bin Laden had actually taken a more daring route, to the north toward Jalalabad, right past the approaching US and British Special Forces and their Afghan allies. After resting there, he proceeded on horseback on a several days’ journey into Konar province, in Afghanistan’s far northeast.” An unnamed US official will tell the Post: “It’s still unclear who bribed who and who talked to who, [but] bin Laden got out. Knowing the land, knowing the people who could direct you, he was able to get out to Konar [and into valleys] that no one has subdued… places the Soviets never pacified.” Al-Zawahiri takes the same route, perhaps traveling with bin Laden. [Washington Post, 5/6/2011] Bin Laden and al-Zawahiri will stay in Konar for months before finally moving to Pakistan (see Late December 2001-Late 2002).
