Persian Gulf War ground campaign: The Coalition forces dominated the air with their technological advantages, but the ground forces were considered to be more evenly matched. Coalition forces had the significant advantage of being able to operate under the protection of air supremacy that had been achieved by their air forces before the start of the main ground offensive. Coalition forces also had two key technological advantages:

  1. The Coalition main battle tanks, such as the U.S. M1 Abrams, British Challenger 1, and Kuwaiti M-84AB were vastly superior to the Chinese Type 69 and domestically built T-72 tanks used by the Iraqis, with crews better trained and armoured doctrine better developed.
  2. The use of GPS made it possible for Coalition forces to navigate without reference to roads or other fixed landmarks. This, along with air reconnaissance, allowed them to fight a battle of maneuver rather than a battle of encounter: they knew where they were and where the enemy was, so they could attack a specific target rather than searching on the ground for enemy forces.

Liberation of Kuwait

American decoy attacks by air attacks and naval gunfire the night before the liberation of Kuwait were designed to make the Iraqis believe the main coalition ground attack would focus on Central Kuwait.For months, American units in Saudi Arabia had been under almost constant Iraqi artillery fire, as well as threats from Scud missile or chemical attacks. On 23 February 1991, the 1st Marine Division, 2nd Marine Division, and the 1st Light Armored Infantry crossed into Kuwait and headed toward Kuwait City. They encountered trenches, barbed wire, and minefields. However, these positions were poorly defended, and were overrun in the first few hours. Several tank battles took place, but apart from that, Coalition troops encountered minimal resistance, as most Iraqi troops surrendered. The general pattern was that the Iraqis would put up a short fight before surrendering. However, Iraqi air defenses shot down nine American aircraft. Meanwhile, forces from Arab countries advanced into Kuwait from the east, encountering little resistance and suffering few casualties.

Despite the successes of Coalition forces, it was feared that the Republican Guard would escape into Iraq before it could be destroyed. It was decided to send British armored forces into Kuwait fifteen hours ahead of schedule, and to send American forces after the Republican Guard. The Coalition advance was preceded by a heavy artillery and rocket barrage, after which 150,000 troops and 1,500 tanks began their advance. Iraqi forces in Kuwait counterattacked against U.S. troops, acting on a direct order from Saddam himself. Despite the intense combat, the Americans repulsed the Iraqis and continued to advance towards Kuwait city.

Kuwaiti forces were tasked with liberating the city. Iraqi troops offered only light resistance. The Kuwaitis lost one soldier killed and one plane shot down, and quickly liberated the city. On 27 February, Saddam ordered a retreat from Kuwait. However, an Iraqi unit at Kuwait International Airport appeared not to have gotten the message, and fiercely resisted. U.S. Marines had to fight for hours before securing the airport, after which Kuwait was declared secure. After four days of fighting, Iraqi forces were expelled from Kuwait. As part of a scorched-earth policy, they set fire to nearly 700 oil wells, and placed land mines around the wells to make extinguishing the fires more difficult.

Initial moves into Iraq

The first units to move into Iraq were three patrols of the B squadron of the British Special Air Service, call signs Bravo One Zero, Bravo Two Zero, and Bravo Three Zero, in late January. These eight-man patrols landed behind Iraqi lines to gather intelligence on the movements of Scud mobile missile launchers, which could not be detected from the air, as they were hidden under bridges and camouflage netting during the day. Other objectives included the destruction of the launchers and their fiber-optic communications arrays that lay in pipelines and relayed coordinates to the TEL operators that were launching attacks against Israel. The operations were designed to prevent any possible Israeli intervention.

Elements of the 2nd Brigade, 1st Cavalry Division of the U.S. Army performed a covert Reconnaissance into Iraq on 9 February 1991, followed by one in force on 20 February that destroyed an Iraqi regiment. From 15–20 February, the Battle of Wadi Al-Batin took place inside Iraq. It was a feint attack, designed to make the Iraqis think that a coalition invasion would take place from the south. The Iraqis fiercely resisted, and the Americans eventually withdrew. Three American soldiers were killed and nine wounded as well as several tanks and armored vehicles destroyed or damaged, but they had taken seven prisoners and destroyed five tanks and twenty prisoners, and successfully deceived the Iraqis. On 22 February 1991, Iraq agreed to a Soviet-proposed ceasefire agreement. The agreement called for Iraq to withdraw troops to pre-invasion positions within six weeks following a total cease-fire, and called for monitoring of the cease-fire and withdrawal to be overseen by the UN Security Council.

The Coalition rejected the proposal, but said that retreating Iraqi forces would not be attacked, and gave twenty-four hours for Iraq to begin withdrawing forces. On 23 February, fighting resulted in the capture of 500 Iraqi soldiers. On 24 February, British and American armoured forces crossed the Iraq/Kuwait border and entered Iraq in large numbers, taking hundreds of prisoners. Iraqi resistance was light, and 4 Americans were killed.

Coalition forces enter Iraq

Shortly afterwards, the U.S. VII Corps in full strength and, spearheaded by the 3rd Squadron of the 2nd Armored Cavalry Regiment (3/2 ACR), launched an armored attack into Iraq early on 24 February, just to the west of Kuwait, taking Iraqi forces by surprise. Simultaneously, the U.S. XVIII Airborne Corps launched a sweeping “left-hook” attack across the largely undefended desert of southern Iraq, led by the 3rd Armoured Cavalry Regiment (3rd ACR) and the 24th Infantry Division (Mechanized). The left flank of this movement was protected by the French 6th Light Armoured Division Daguet.

The French force quickly overcame the Iraqi 45th Infantry Division, suffering light casualties and taking a large number of prisoners, and took up blocking positions to prevent an Iraqi counter-attack on the Coalition flank. The right flank of the movement was protected by the British 1st Armoured Division. Once the allies had penetrated deep into Iraqi territory, they turned eastward, launching a flank attack against the elite Republican Guard before it could escape. The Iraqis resisted fiercely from dug-in positions and stationary vehicles, and even mounted armored charges.

Unlike many previous engagements, the destruction of the first Iraqi tanks did not result in a mass surrender. The Iraqis suffered massive losses and lost dozens of tanks and vehicles, while American casualties were comparatively low, with a single Bradley knocked out. Coalition forces pressed another ten kilometers into Iraqi territory, and captured their objective within three hours. They took 500 prisoners and inflicted heavy losses, decimating the Iraqi 26th Infantry Division. An American soldier was killed by an Iraqi land mine, another five by friendly fire, and thirty wounded during the battle. American forces breached Iraqi defenses and decimated an entire Iraqi infantry division. Meanwhile, British forces attacked the Iraqi Medina Division and a major Republican Guard logistics base. In nearly two days of some of the war's most intense fighting, the British destroyed 40 enemy tanks and captured a division commander.

Meanwhile, American forces attacked the village of Al Busayyah, meeting fierce resistance. They suffered no casualties, but destroyed a considerable amount of military hardware and took prisoners.

On 25 February 1991, Iraqi forces fired a scud missile at an American barracks in Dhahran, Saudi Arabia. The missile attack killed 28 American military personnel.

The Coalition advance was much swifter than U.S. generals had expected. On 26 February, Iraqi troops began retreating from Kuwait, after they had set its oil fields on fire (737 oil wells were set on fire). A long convoy of retreating Iraqi troops formed along the main Iraq-Kuwait highway. Although they were retreating, this convoy was bombed so extensively by Coalition air forces that it came to be known as the Highway of Death. Hundreds of Iraqi troops were killed. Forces from the United States, the United Kingdom, and France continued to pursue retreating Iraqi forces over the border and back into Iraq, eventually moving to within 150 miles (240 km) of Baghdad before withdrawing from the Iraqi border.

One hundred hours after the ground campaign started, on 28 February, President Bush declared a ceasefire, and he also declared that Kuwait had been liberated.
