One thing, though, seemed evident: the units closest to Benghazi seemed to have been hit with their cannons and machine guns still pointing towards the rebel capital.
To the south, though, many had been hit as they headed away from the city in a headlong dash for escape on the long road leading to a distant Tripoli.
“They were retreating,” said Col. Abdullah al-Shafi, an officer in the rebel forces which had clamored desperately for the help that arrived on Saturday. “Soldiers had taken civilians cars and fled. They were ditching their fatigues.”

“This is all France,” a rebel fighter, Tahir Sassi, told a Reuters correspondent as he surveyed the devastation on Sunday. “Today we came through and saw the road open.”
