The Iranian high command passed from regular military leaders to clergy in mid-1982. In March of same year, Tehran launched its Operation Undeniable Victory, which marked a major turning point, as Iran penetrated Iraq's "impenetrable" lines, split Iraq's forces, and forced the Iraqis to retreat. Its forces broke the Iraqi line near Sousangerd, separating Iraqi units in northern and southern Khouzestan. Within a week, they succeeded in destroying a large part of three Iraqi divisions. This operation, another combined effort of the army, Pasdaran, and Basij, was a turning point in the war because the strategic initiative shifted from Iraq to Iran.
In May 1982, Iranian units finally regained Khorramshahr, but with high casualties. After this victory, the Iranians maintained the pressure on the remaining Iraqi forces, and President Saddam Hussein announced that the Iraqi units would withdraw from Iranian territory. Saddam ordered a withdrawal to the international borders, believing Iran would agree to end the war. Iran did not accept this withdrawal as the end of the conflict, and continued the war into Iraq. In late June 1982, Baghdad stated its willingness to negotiate a settlement of the war and to withdraw its forces from Iran. Iran refused.
In July 1982 Iran launched Operation Ramadan on Iraqi territory, near Basra. Although Basra was within range of Iranian artillery, the clergy used "human-wave" attacks by the Pasdaran and Basij against the city's defenses, apparently waiting for a coup to topple Saddam Hussein. Tehran used Pasdaran forces and Basij volunteers in one of the biggest land battles since 1945. Ranging in age from only nine to more than fifty, these eager but relatively untrained soldiers swept over minefields and fortifications to clear safe paths for the tanks. All such assaults faced Iraqi artillery fire and received heavy casualties. The Iranians sustained an immmense number of casualties, but they enabled Iran to recover some territory before the Iraqis could repulse the bulk of the invading forces.
By the end of 1982, Iraq had been resupplied with new Soviet materiel, and the ground war entered a new phase. Iraq used newly acquired T-55 tanks and T-62 tanks, BM-21 Stalin Organ rocket launchers, and Mi-24 helicopter gunships to prepare a Soviet-type three-line defense, replete with obstacles, minefields, and fortified positions. The Combat Engineer Corps proved efficient in constructing bridges across water obstacles, in laying minefields, and in preparing new defense lines and fortifications.
Throughout 1983 both sides demonstrated their ability to absorb and to inflict severe losses. Iraq, in particular, proved adroit at constructing defensive strong points and flooding lowland areas to stymie the Iranian thrusts, hampering the advance of mechanized units. Both sides also experienced difficulties in effectively utilizing their armor. Rather than maneuver their armor, they tended to dig in tanks and use them as artillery pieces. Furthermore, both sides failed to master tank gunsights and fire controls, making themselves vulnerable to antitank weapons.
Iranian Troops on the move
In 1983 Iran launched three major, but unsuccessful, human wave offensives, with huge losses, along the frontier. On February 6, Tehran, using 200,000 "last reserve" Pasdaran troops, attacked along a 40-kilometer stretch near Al Amarah, about 200 kilometers southeast of Baghdad. Backed by air, armor, and artillery support, Iran's six-division thrust was strong enough to break through. In response, Baghdad used massive air attacks, with more than 200 sorties, many flown by attack helicopters. More than 6,000 Iranians were killed that day, while achieving only minute gains. In April 1983, the Mandali-Baghdad northcentral sector witnessed fierce fighting, as repeated Iranian attacks were stopped by Iraqi mechanized and infantry divisions. Casualties were very high, and by the end of 1983, an estimated 120,000 Iranians and 60,000 Iraqis had been killed. Despite these losses, in 1983 Iran held a distinct advantage in the attempt to wage and eventually to win the war of attrition.
Beginning in 1984, Baghdad's military goal changed from controlling Iranian territory to denying Tehran any major gain inside Iraq. Furthermore, Iraq tried to force Iran to the negotiating table by various means. First, President Saddam Hussein sought to increase the war's manpower and economic cost to Iran. For this purpose, Iraq purchased new weapons, mainly from the Soviet Union and France. Iraq also completed the construction of what came to be known as "killing zones" (which consisted primarily of artificially flooded areas near Basra) to stop Iranian units. In addition, Baghdad used chemical weapons against Iranian troop concentrations and launched attacks on many economic centers. Despite Iraqi determination to halt further Iranian progress, Iranian units in March 1984 captured parts of the Majnoun Islands, whose oil fields had economic as well as strategic value.
Second, Iraq turned to diplomatic and political means. In April 1984, Saddam Hussein proposed to meet Khomeini personally in a neutral location to discuss peace negotiations. But Tehran rejected this offer and restated its refusal to negotiate with President Saddam Hussein.
Third, Iraq sought to involve the superpowers as a means of ending the war. The Iraqis believed this objective could be achieved by attacking Iranian shipping. Initially, Baghdad used borrowed French Super Etendard aircraft armed with Exocets. In 1984 Iraq returned these airplanes to France and purchased approximately thirty Mirage F-1 fighters equipped with Exocet missiles. Iraq launched a new series of attacks on shipping on February 1, 1984.
The War of Attrition, 1984 - 1987
Iranian troops under Iraqi Chemical Weapon attacks
By 1984 it was reported that some 300,000 Iranian soldiers and 250,000 Iraqi troops had been killed, or wounded. Most foreign military analysts felt that neither Iraq nor Iran used its modern equipment efficiently. Frequently, sophisticated materiel was left unused, when a massive modern assault could have won the battle for either side. Tanks and armored vehicles were dug in and used as artillery pieces, instead of being maneuvered to lead or to support an assault. William O. Staudenmaeir, a seasoned military analyst, reported that "the land-computing sights on the Iraqi tanks [were] seldom used. This lower[ed] the accuracy of the T-62 tanks to World War II standards." This was the result of poorly educated and trained commissioned officers and field commanders. In addition, both sides frequently abandoned heavy equipment in the battle zone because they lacked the skilled technical personnel needed to carry out minor repairs.
Analysts also assert that the two states' armies showed little coordination and that some units in the field have been left to fight largely on their own. In this protracted war of attrition, soldiers and officers alike failed to display initiative or professional expertise in combat. Difficult decisions, which should have had immediate attention, were referred by section commanders to the capitals for action. Except for the predictable bursts on important anniversaries, by the mid-1980s the war was stalemated.
In early 1984, Iran had begun Operation Dawn V, which was meant to split the Iraqi 3rd Army Corps and 4th Army Corps near Basra. In early 1984, an estimated 500,000 Pasdaran and Basij forces, using shallow boats or on foot, moved to within a few kilometers of the strategic Basra-Baghdad waterway. Between February 29 and March 1, in one of the largest battles of the war, the two armies clashed and inflicted more than 25,000 fatalities on each other. Without armored and air support of their own, the Iranians faced Iraqi tanks, mortars, and helicopter gunships. Within a few weeks, Tehran opened another front in the shallow lakes of the Hawizah Marshes, just east of Al Qurnah, in Iraq, near the confluence of the Tigris and Euphrates rivers. Iraqi forces, using Soviet- and French-made helicopter gunships, inflicted heavy casualties on the five Iranian brigades (15,000 men) in this Battle of Majnoun. Lacking the equipment to open secure passages through Iraqi minefields, and having too few tanks, the Iranian command again resorted to the human-wave tactic. In March 1984, an East European journalist claimed that he "saw tens of thousands of young boys, roped together in groups of about twenty to prevent the faint-hearted from deserting, make such an attack." The Iranians made little progress despite these sacrifices. Perhaps as a result of this performance, Tehran, for the first time, used a regular army unit, the 92nd Armored Division, at the Battle of the Marshes a few weeks later.
In February 1984 the Iraqi command ordered the use of chemical weapons. Despite repeated Iraqi denials, between May 1981 and March 1984, Iran charged Iraq with forty uses of chemical weapons. The year 1984 closed with part of the Majnoun Islands and a few pockets of Iraqi territory in Iranian hands. Casualties notwithstanding, Tehran had maintained its military posture, while Baghdad was reevaluating its overall strategy.
The major development in 1985 was the increased targeting of population centers and industrial facilities by both combatants. In May Iraq began aircraft attacks, long-range artillery attacks, and surface-to-surface missile attacks on Tehran and on other major Iranian cities. Between August and November, Iraq raided Khark Island forty-four times in a futile attempt to destroy its installations. Iran responded with its own air raids and missile attacks on Baghdad and other Iraqi towns. In addition, Tehran systematized its periodic stop-and-search operations, which were conducted to verify the cargo contents of ships in the Persian Gulf and to seize war materiel destined for Iraq.
Iranian Artillery Battery
The only major ground offensive, involving an estimated 60,000 Iranian troops, occurred in March 1985, near Basra; once again, the assault proved inconclusive except for heavy casualties. In 1986, however, Iraq suffered a major loss in the southern region. On February 9, Iran launched a successful surprise amphibious assault across the Arvand-Roud (Shatt al Arab) and captured the abandoned Iraqi oil port of Al Faw. The occupation of Al Faw, a logistical feat, involved 30,000 regular Iranian soldiers who rapidly entrenched themselves. Saddam Hussein vowed to eliminate the bridgehead "at all costs," and in April 1988 the Iraqis succeeded in regaining the Al Faw peninsula.
Late, in March 1986, the UN secretary general, Javier Perez de Cuellar, formally accused Iraq of using chemical weapons against Iran. Citing the report of four chemical warfare experts whom the UN had sent to Iran in February and March 1986, the secretary general called on Baghdad to end its violation of the 1925 Geneva Protocol on the use of chemical weapons. The UN report concluded that "Iraqi forces have used chemical warfare against Iranian forces"; the weapons used included both mustard gas and nerve gas. The report further stated that "the use of chemical weapons appear[ed] to be more extensive [in 1981] than in 1984." Iraq attempted to deny using chemicals, but the evidence, in the form of many badly burned casualties flown to European hospitals for treatment, was overwhelming. According to a British representative at the Conference on Disarmament in Geneva in July 1986, "Iraqi chemical warfare was responsible for about 10,000 casualties." In March 1988, Iraq was again charged with a major use of chemical warfare while retaking Halabjah, a Kurdish town in northeastern Iraq, near the Iranian border.
Unable in 1986, however, to dislodge the Iranians from Al Faw, the Iraqis went on the offensive; they captured the city of Mehran in May, only to lose it in July 1986. The rest of 1986 witnessed small hit-and-run attacks by both sides, while the Iranians massed almost 500,000 troops for another promised "final offensive," which did not occur. But the Iraqis, perhaps for the first time since the outbreak of hostilities, began a concerted air-strike campaign in July. Heavy attacks on Khark Island forced Iran to rely on makeshift installations farther south in the Persian Gulf at Sirri Island and Larak Island. Thereupon, Iraqi jets, refueling in midair and using a Saudi military base, hit Sirri and Larak. The two belligerents also attacked 111 neutral ships in the Persian Gulf in 1986.
Iranian troops in their trenches
Meanwhile, to help defend itself, Iraq had built impressive fortifications along the 1,200-kilometer war front. Iraq devoted particular attention to the southern city of Basra, where concrete-roofed bunkers, tank- and artillery-firing positions, minefields, and stretches of barbed wire, all shielded by an artificially flooded lake 30 kilometers long and 1,800 meters wide, were constructed. Most visitors to the area acknowledged Iraq's effective use of combat engineering to erect these barriers.
By late 1986, rumors of a final Iranian offensive against Basra proliferated. On 08 January 1987, Operation Karbala Five began, with Iranian units pushing westward between Fish Lake and the Arvand-Roud (Shatt al Arab). This annual "final offensive" captured the town of Duayji and inflicted 20,000 casualties on Iraq, but at the higher cost of Iranian casualties. In this intensive operation, Baghdad also lost forty-five airplanes. Attempting to capture Basra, Tehran launched several attacks, some of them well-disguised diversion assaults such as Operation Karbala Six and Operation Karbala Seven. Iran finally aborted Operation Karbala Five on 26 February 1987. Although the Iranian push came close to breaking Iraq's last line of defense east of Basra, Tehran was unable to score the decisive breakthrough required to win outright victory, or even to secure relative gains over Iraq.
In late May 1987, just when the war seemed to have reached a complete stalemate on the southern front, reports from Iran indicated that the conflict was intensifying on Iraq's northern front. This assault, Operation Karbala Ten, was a joint effort by Iranian units and Iraqi Kurdish rebels. They surrounded the garrison at Mawat, endangering Iraq's oil fields near Kirkuk and the northern oil pipeline to Turkey. Believing it could win the war merely by holding the line and inflicting unacceptable losses on the attacking Iranians, Iraq initially adopted a static defensive strategy. This was successful in repelling successive Iranian offensives until 1986 and 1987, when the Al-Faw peninsula was lost and Iranian troops reached the gates of Al-Basrah. Embarrassed by the loss of the peninsula and concerned by the threat to his second largest city, Saddam ordered a change in strategy. From a defensive posture, in which the only offensive operations were counterattacks to relieve forces under pressure or to exploit failed Iranian assaults, the Iraqis adopted an offensive strategy. More decision-making authority was delegated to senior military commanders. The change also indicated a maturing of Iraqi military capabilities and an improvement in the armed forces' effectiveness. The success of this new strategy, plus the attendant change in doctrine and procedures virtually eliminated Iranian military capabilities. As the war continued, Iran was increasingly short of spare parts for damaged airplanes and had lost a large number of airplanes in combat. As a result, by late 1987 Iran had become less able to mount an effective defense against the massively resupplied Iraqi air and ground forces.
