After the launch of Operation Desert Storm on 17 January 1991, the US-led coalition forces had first swept the skies of Iraqi aircraft and then, starting on 24 February they launched a ground invasion. They expected to face fierce resistance from the large - at least of paper - Iraqi army. This ground war lasted only 100 hours as the armed forces of Saddam were no match for the modern armies that they faced.
At 8 am on 28 February 1991 the First Gulf War ended with US President George H.W. Bush ordering the US-led forces to cease hostilities as the retreat of Iraqi forces was turning into a bloody rout, with coalition aircraft led by USAF A-10s killing thousands of Iraqi troops and destroying hundreds of tanks in the infamous 'Highway of Death'. Though sporadic fighting would continue into March, 28 February marked the end of combat operations in the war
