But the rebels have been unable or unwilling to move forward without allied airstrikes, which have grounded Kadafi's air force and robbed his forces of some of the heavy weapons they have used to overwhelm the rebels.
"Where is Sarkozy? Where is Obama?" asked Hussam Bernwi, 36, an exterminator wielding an assault rifle, referring to attacks by French and American warplanes and missiles.
Many rebels regard allied warplanes as their personal air force, though the U.N. Security Council resolution authorizing attacks against Kadafi forces threatening civilians does not extend to close air support for rebel forces.
Among the rebels fleeing Bin Jawwad and points west was Mohammed Fatallah, 42, a businessman armed with a submachine gun manufactured in 1949. He said he feared Grad rockets too much to join other rebels fighting to hold Bin Jawwad.
"If the planes will hit Kadafi's men, well, then I'll go there and fight," Fatallah said. "If the planes don't attack, we'll get pushed back even more."
