Following its capture, the Iranian city of
Khorramshahr remained under Iraqi control until April 1982, when the Iranians launched
Operation Beit ol-Moqaddas to recapture the occupied parts of the province of
Khuzestan. The initial phase of the operation took place from 24 April to 12 May 1982 and consisted of approximately 70,000
Iranian Army troops and
Revolutionary Guards, who pushed the Iraqi forces out of the
Ahvaz–
Susangerd area while suffering many casualties. The Iraqis withdrew to Khorramshahr and, on 20 May, launched a vigorous counter-attack against the Iranians that failed. Iran then launched an all-out assault on Khorramshahr and overran two Iraqi defensive lines in the
Pol-e Now and
Shalamcheh region. The Iranians concentrated near the
Shatt al-Arab (known as the
Arvand Rud in Iran) waterway, besieged Khorramshahr, and recaptured the city on 24 May 1982, after two days of intense and bloody fighting. The mobile bridge constructed by the Iraqi army, connecting the islands of Bowarin and Umm Rasas, to the southern shore of the Arvand River, was rendered inoperable by the fighters of the Islamic Republic of Iran and the Iraqi forces were unable to use it. The Iraqi soldiers, faced with the obstruction on the Shalamcheh road, were mentally shaken, causing them to surrender. == Aftermath and legacy ==
