A convoy of revolutionary forces head to to the frontline in Bani Walid, at a checkpoint in Wadi Dinar, Libya, Friday, Sept. 16, 2011. Libyan fighters are signing up for a final assault on one of the last remaining bastions of Moammar Gadhafi. The volunteers are pouring in by the dozens, coming in pickup trucks from cities as far as Tripoli and Tobruk, as a deadline expired on Saturday for the pro-Gadhafi loyalists holed up inside the town of Bani Walid to surrender.
