Gulf War: The Battle of Khafji, the first major ground engagement of the war, as well as its deadliest, begins between Iraq and Saudi Arabia.

The Gulf War was an armed conflict between Iraq and a 42-country coalition led by the United States. The coalition's efforts were in two phases: Operation Desert Shield, which marked the military buildup from August 1990 to January 1991; and Operation Desert Storm, from the bombing campaign against Iraq on 17 January until the American-led liberation of Kuwait on 28 February.
