Battle of 73 Easting

The Battle of 73 Easting was a decisive tank battle fought on 26 February 1991, during the Gulf War, between American-British armored forces and those of the Iraqi Republican Guard. The battle took place several hours after the Battle of Al Busayyah. It was named for a UTM north-south coordinate line (an "Easting", measured in kilometers and readable on GPS receivers) in the featureless desert that was used as a phase line to measure progress of the offensive. The battle was described by the Military Channel as "the last great tank battle of the 20th century."

The main U.S. unit in the battle was the 2nd Armored Cavalry Regiment (2nd ACR), a 4,500 man reconnaissance and security element assigned to VII Corps. It consisted of three ground squadrons (1st, 2nd and 3rd), an aviation (attack helicopter) squadron (4th), and a support squadron. The 2ACR combat team numbered around 10,000 soldiers. Each ground squadron was made up of three cavalry troops, a tank company, a self-propelled howitzer battery, and a headquarters troop. Each troop comprised 120 soldiers, 12 M3 Bradley fighting vehicles and nine M1A1 Abrams main battle tanks. The corps' main body consisted of the American 3rd Armored Division (3rd AD) and 1st Infantry Division (1st ID) and 1st Armored Division (1st AD), and the British 1st Armoured Division (1 AD).

The job of 2ACR was to advance east, led by scouts in Bradleys with tanks covering them from the rear, and to locate the enemy at a distance. They covered the advance of the 3rd Armored Division until late on February 25 and then covered the movement of 1st Infantry Division as it moved north from its initial objectives. The Regiment's mission was to strip away enemy security forces, clear the way of significant defenses and locate the Republican Guard's defensive positions so they could be engaged by the full weight of the armored forces.

On the night of 23/24 February, in accordance with General Norman Schwarzkopf's plan for the ground assault called "Operation Desert Sabre", VII Corps raced east from Saudi Arabia into Iraq in a maneuver later nicknamed the "Hail Mary." The Corps had two goals: to cut off Iraqi retreat from Kuwait, and to destroy five Republican Guard divisions near the Iraq-Kuwait border that might attack the Arab and Marine units moving into Kuwait to the south. Initial Iraqi resistance was light and scattered and the 2nd ACR fought only minor engagements until 25 February.

The primary battle was conducted by 2ACR's three squadrons of about 400 soldiers, along with the 1st Infantry Division's two leading brigades, who attacked and destroyed the Iraqi 18th Mechanized Brigade and 37th Armored Brigade of the Tawakalna Division, each consisting of between 2,500 to 3,000 personnel.

Famous quotes containing the words battle of and/or battle:

    The militancy of men, through all the centuries, has drenched the world with blood, and for these deeds of horror and destruction men have been rewarded with monuments, with great songs and epics. The militancy of women has harmed no human life save the lives of those who fought the battle of righteousness. Time alone will reveal what reward will be allotted to women.
    Emmeline Pankhurst (1858–1928)

    That we can come here today and in the presence of thousands and tens of thousands of the survivors of the gallant army of Northern Virginia and their descendants, establish such an enduring monument by their hospitable welcome and acclaim, is conclusive proof of the uniting of the sections, and a universal confession that all that was done was well done, that the battle had to be fought, that the sections had to be tried, but that in the end, the result has inured to the common benefit of all.
    William Howard Taft (1857–1930)
