The Iraqi invasion of Kuwait was an operation conducted by Iraq on 2 August 1990, whereby it invaded the neighboring State of Kuwait, consequently resulting in a seven-month-long Iraqi military occupation of the country. The invasion and Iraq's subsequent refusal to withdraw from Kuwait by a deadline mandated by the United Nations led to a direct military intervention by a United Nations-authorized coalition of forces led by the United States. These events came to be known as the first Gulf War, eventually resulting in the forced expulsion of Iraqi troops from Kuwait and the Iraqis setting 600 Kuwaiti oil wells on fire during their retreat, as a scorched earth strategy.
The invasion started on 2 August 1990, and within two days, most of the Kuwaiti military was either overrun by the Iraqi Republican Guard or retreated to neighboring Saudi Arabia and Bahrain. Towards the end of the first day of the invasion, only pockets of resistance were left in the country. By 3 August, the last military units were desperately fighting delaying actions at choke points and other defensible positions throughout the country until out of ammunition or overrun by Iraqi forces. Ali al-Salem Air Base of the Kuwaiti Air Force was the only base still unoccupied on 3 August, and Kuwaiti aircraft flew resupply missions from Saudi Arabia throughout the day in an effort to mount a defense. However, by nightfall, Ali al-Salem Air Base had been overrun by Iraqi forces.
