The regime of ex-Iraqi dictator Saddam Hussein attacked Iran in 1980, a year after the victory of the Islamic Revolution.
Saddam vowed to conquer Iran’s strategic port city of Khorramshahr within the first week of the invasion. He finally managed to occupy the city after 34 days. Iranians launched a large-scale operation in 1982 to recapture the city. Khorramshahr liberation was a severe blow to Saddam’s regime.
