At 4 a.m. on 24 February, after being shelled for months and under the constant threat of a gas attack, the United States 1st and 2nd Marine Divisions crossed into Kuwait. They maneuvered around vast systems of barbed wire, minefields and trenches. Once into Kuwait, they headed towards Kuwait City. The troops themselves encountered little resistance and, apart from several minor tank battles, were met primarily by surrendering soldiers. The general pattern was that coalition troops would encounter Iraqi soldiers who would put up a brief fight before deciding to surrender.

On 27 February, Saddam Hussein issued a retreat order to his troops in Kuwait; however, one unit of Iraqi troops appeared to have not gotten the retreat order. When the U.S. Marines arrived at Kuwait International Airport, they encountered fierce resistance, and it took them several hours to gain control and secure the airport. As part of the retreat order, the Iraqis carried out a "scorched earth" policy that included setting hundreds of oil wells on fire in an effort to destroy the Kuwaiti economy. After the battle at Kuwait International Airport, the U.S. Marines stopped at the outskirts of Kuwait City, allowing their coalition allies to take and occupy Kuwait City, effectively ending combat operations in the Kuwaiti theater of the war.

After four days of fighting, all Iraqi troops were expelled from Kuwait, ending a nearly seven-month occupation of Kuwait by Iraq. A little over 1,100 casualties were suffered by the Coalition. Estimates of Iraqi casualties range from 30,000 to 150,000. Iraq lost thousands of vehicles, while the advancing Coalition lost relatively few; Iraq's obsolete Soviet T-72 tanks proved no match for the American M1 Abrams and British Challenger tanks.
