The First Gulf War

Part Four

On the night of February 26 and February 27 1991, defeated Iraqi forces began leaving Kuwait on the main highway north of Al Jahra in a column of some 1400 vehicles. US Air Force and US Navy jets pursued and destroyed the convoy, subjecting it to sustained bombing for several hours. Due to the attack being carried out by high-flying fixed-wing aircraft, the Iraqi troops were not given any opportunities to surrender.
