25 August 2011 Last updated at 03:39 BST
Columns of Libyan rebels are on the road towards the city of Sirte, Col Gaddafi's hometown and the place many believe he could make his last stand.
But pro-Gaddafi forces are still offering serious resistance, bringing the fight to the advancing rebels as far as 60 miles (100km) from the town.
Paul Wood is travelling with the rebels on the road to Sirte, from where he sent this report.
