Second Battle of al-Faw

The al-Faw peninsula had been under Iranian control since 1986 when they launched a surprise attack on the peninsula as part of the larger Operation Dawn 8.

The taking of the peninsula by the Iranians was a strong blow to Iraq's prestige whilst also threatening Basra from the south-east. The retaking of the peninsula was seen by Saddam Hussein as a top priority, and Iraqi General Maher Abd al-Rashid promised to recover the peninsula, going so far as to offer his daughter Sahar to Saddam's son Qusay to show his certainty.^[17] Planning for the recovery of the peninsula began soon after it had been taken by the Iranians, and was largely done in secret by a small group of six, with Saddam Hussein himself being heavily involved in the planning process. The operation was called "Operation Ramadan Mubarak", which later would become included as a part of the Tawakal ala Allah operations due to its success.

For the second battle of Faw the Iraqis had concentrated over 100,000 soldiers, of whom approximately 60% were Republican Guard, against some 15,000 Iranian Basij volunteers. The Iraqi command had expected the battle to take several weeks, but Iraqi forces seized the peninsula in a single day with only minimal losses, due to the collapse of the Iranian units present.^[9] This stunning success led the Iraqi command to expand the original battle into a larger offensive campaign against Iran.

The attack on al-Faw was preceded by Iraqi diversionary attacks in northern Iraq, with a massive artillery and air barrage of Iranian front lines. Key areas, such as supply lines, command posts, and ammunition depots, were hit by a storm of mustard gas and nerve gas, as well as by conventional explosives. Helicopters landed Iraqi commandos behind Iranian lines while the main Iraqi force attacked in a frontal assault. Within 48 hours, all of the Iranian forces had been killed or cleared from the al-Faw Peninsula.[43] The day was celebrated in Iraq as Faw Liberation Day throughout Saddam's rule. The Iraqis had planned the offensive well. Prior to the attack the Iraqi soldiers gave themselves poison gas antidotes to shield themselves from the effect of the saturation of gas. The heavy and well executed use of chemical weapons was the decisive factor in the Iraqi victory.[101] Iraqi losses were a little more than 1,000.[39]

To the shock of the Iranians, rather than breaking off the offensive, the Iraqis kept up their drive, and a new force attacked the Iranian positions around Basra.[20] Following this, sensing Iranian weakness, the Iraqis launched a sustained drive to clear the Iranians out of all of southern Iraq.[26]:264

One of the most successful Iraqi tactics was the "one-two punch" attack using chemical weapons. Using artillery, they would saturate the Iranian front line with rapidly dispersing cyanide and nerve gas, while longer-lasting mustard gas was launched via fighter-bombers and rockets against the Iranian rear, creating a "chemical wall" that blocked reinforcement

Battle of Fish Lake

At 9:30am on 25 May 1988, Iraq launched what became known as Tawakalna 1,^[18] consisting of one of the largest artillery barrages in history, coupled with chemical weapons. The marshes had previously been dried by a mixture of drought and Iraqi engineering, despite Iranian attempts at refilling the marshes. The drying of the marshes allowed the Iraqis to use tanks more effectively to bypass and then crush Iranian field fortifications. The Iraqi forces deployed consisted of possibly up to 135,000 men composed of various elements of the Republican Guard and 3rd Corps, attacking along a 15-mile front. Iraqi numerical superiority in infantry compared to the Iranians was around 4 to 1. Iraqi forces attacked Iranian positions at Fish Lake, at a point east of Basra, and to a lesser extent at a point further to the north.^[12]

Iran's defenses consisted of trenches, sand mounts, anti-tank ditches, barbed wire, and minefields.^[12]

Iraqi forces drove across the Jassem canal, on the Basra-Khorramshahr road, and cleared a 15-mile corridor to the east and southeast following. Initial Iranian resistance was stiff, with Iraqi forces taking some casualties when first penetrating the Iranian defenses. Following an Iranian counterattack which was repulsed, a renewed Iraqi offensive utilizing helicopters and chemical weapons forced a hasty withdrawal, with some reports suggesting that the Iranians fell back in disarray.^[12]

Iran suffered somewhere in the region of six to eight times the casualties felt by Iraq. Iraqi forces thus managed to expel the Iranians after less than 10 hours of combat due to weak resistance. The Iranian forces were pushed all the way across the border, which Iran had captured at the cost of 65,000 casualties just a year earlier.^{[12][19][20]: 265} In addition, the Iranians were permanently driven away from Basra.^[12] The battle dealt a heavy blow to Iranian morale, with recruitment dropping off by 70%. The loss of equipment also affected Iran due to its difficulty in replacing armoured units.^[12]

Iranian counterattack

Faced with such losses, Khomeini appointed the cleric Hashemi Rafsanjani as the Supreme Commander of the Armed Forces, though he had in actuality occupied that position for months. Rafsanjani desperately ordered a hasty counter-attack called Operation Beit al-Moqaddas-7,^[21] which was launched 12–15 June 1988. The Iranians, counter-attacked with a force of 20,000–25,000 Revolutionary Guards in formations of as many as 50 battalions, and managed to strike Saddam's presidential palace in Baghdad using fighter aircraft.[12] After 3 days of fierce fighting which decimated the Revolutionary Guards force, the Iranians were driven back as the Iraqis launched 650 helicopter and 300 aircraft ground-attack sorties. The offensive showed that Iran still had the ability to fight back. At the same time it showed that Iran had done little to improve its military capabilities, leaning on revolutionary orthodoxy instead of military professionalism.^[12]

Second battle of the Majnoon Islands

On 25 June, Iraq launched the second Tawakal ala Allah operation liberating Majnoon Island.^[18] Hundreds of tanks were used against the Iranians, with Iraqi forces present outnumbering Iranian forces up to a factor of 20 to 1.^[22] The Iraqi Republican Guard forces had prepared for the battle by launching attacks against mockups of the island. The attack began with one of the largest artillery barrages in history, coupled with massive amounts of poison gas, incapacitating many of the defenders. The Iraqi air force provided close support by performing 400 ground-attack sorties. Iran committed 35 fighter aircraft in a desperate attempt to counter-act Iraq's combined air and artillery support while at the same time attempting to hinder the advance of Iraqi forces, but the Iranians were simply overwhelmed in the sky and on the ground. Iraqi commandos using amphibious craft blocked the rear of the island. Some reports also indicate that a brigade of Iraqi paratroopers were dropped behind the Iranian forces, which would have been the first use of airborne troops since the start of the war. The Iraqi ground assault began at 3:30 AM, when an assault force using amphibious armored vehicles and boats landed on the island. Afterwards, they immediately set up pontoon bridges and crossed large amounts of forces onto the island. The Iranians had little time to react as they were hit by the huge military "sledgehammer". The Iraqis used 2,000 tanks against 60 Iranian ones.^[12]

While Iraqi Republican Guards forces cleared the two islands the Iraqi Third Corps protected their Eastern flank and severed Iranian ties to the mainland, with the help of hovercraft equipped commandos. The battle resulted in over 2,115 prisoners,^[22] with the Iranian forces being overwhelmed in 8 hours of combat.^{[citation needed]} Saddam appeared live on Iraqi state television to "lead" the charge against the Iranians.^[12] The vast majority of the Iranian defenders were killed during the quick assault, with relatively few taken prisoner.^[18]

Renewed offensives into Iran; the Battle of Qasr Shirin and the Battle of Dehloran

The final two Tawakal Ala Allah operations took place in Amarah in the direction of Dehloran and Khanaqin in the direction of Qasre Shirin.^[18] On July 12, Iraqi forces shelled the Iranian positions around the Zubaidat area near the border, a group of oil fields east of Amarah. These were some of the last occupied positions on Iraqi territory, and the shelling was soon followed by a new Iraqi attack with a force of about five divisions. At 7:30 AM, Republican Guards forces, and forces from Iraq's 4th Corps, advanced on the Iranian positions. It is unclear whether Iraq used gas, but the Iranian defenses quickly collapsed. Within a matter of hours, Iraq was in control of virtually all of the Iranian positions on its territory, and took roughly 2,500 Iranian prisoners.^[23] By 12 July at the central front, the Iraqis had driven away from Amarah,^[12] and moved into Iran on a broad offensive, swept aside scattered Iranian resistance, and captured the city of Dehloran and Qasre Shirin, 30 kilometres (19 mi) and 20 kilometres (12 mi) respectively inside Iran, and captured another 2,500 Iranian troops along with substantial amount of armour and materiel,^[12] which took days to transport to Iraq. In addition the Iraqis captured the Iranian towns of Sumar, Naft Shahr, Sarpol Zahab, Saleh Abad, Mousiyan, Patak, as well as dozens of other towns along the central and southern portions of the border, along with occupying and cutting off the strategically important Ahvaz-Khorramshahr highway and in places reaching and occupying important crossing-points on the Karkheh river. The intention was to push Khomeini to accept UN security council resolution 598. Had Iran not accepted the ceasefire and had Iraq willed it, Iraq could have continued to occupy this Iranian territory. However, soon after Khomeini's acceptance of the UN ceasefire deal on 20 July 1988, the Iraqis withdrew from the towns, claiming that they had no desire to conquer Iranian territory. Iraq had proved that Iran could no longer occupy Iraqi territory, and showed the rejuvenated power of Iraq's Army after being resupplied by the USSR the previous two years.^[24]
