Former rebels, escorting Gadhafi loyalists taken as prisoners in the front line, unseen, go through a checkpoint in Wish Tata, Libya, Friday, Sept. 9, 2011. Libya's rebels have surrounded the ousted dictator Moammar Gadhafi, and it is only a matter of time until he is captured or killed, a spokesman for Tripoli's new military council said Wednesday.

WISHTATA, Libya — 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.

At a mosque in Wishtata, a hamlet about 25 miles (40 kilometers) from Bani Walid, the volunteers crowded around a desk to register their names and blood type.

Teacher Abdel Wahab Milad from nearby town of Gharyan says he's joining the fight because it's time to "get rid of Gadhafi once and for all."

Libyan fighters on Friday launched a two-pronged assault on Bani Walid after a weeklong standoff over a peaceful surrender dissolved.
