Liberation of Khorramshahr: Iranians recapture of the port city of Khorramshahr from the Iraqis during the Iran-Iraq War.

The battle of Khorramshahr, also known in Iran as the liberation of Khorramshahr (Persian: آزادسازی خرمشهر, romanized: Âzâdsâzī-ye Khorramshahr) was the Iranian recapture of the city of Khorramshahr on 24 May 1982, during the Iran–Iraq War. The city had been captured by the Iraqis earlier in the war, on 26 October 1980, shortly after the Iraqi invasion of Iran. The successful retaking of the city was part of Iran's Operation Beit ol-Moqaddas. It is perceived as a turning point in the war; and the liberation of the city is annually celebrated in Iran on 24 May.
