The Liberation anniversary of Khorramshahr City On 24 May 1982

Khorramshahr is a port city in the Khuzestan province in southwestern Iran. It is approximately ten kilometers north of Abadan. The city extends to the right bank of the Arvand River near its confluent with the Karun River at the junction of the Karun and Shatt al Arab rivers, on the border between Iran and Iraq.
From the beginning of the 20th century until 1980, the city was the main commercial port of Iran which is called Bandar-e-Khorramshahr. A port has existed on the site at least since the time Alexander the Great invaded Iran in 331 BC.
From about 300 BC to AD 1200, the city derived considerable prosperity from trade. In ancient times it had been known as Piyan, and later Bayan.
Khorramshahr"s importance in the 20th century stemmed from its nearness to Abadan, which is situated on a nearby river island and was home to the world’s largest oil refinery at one time. Oil was discovered in Iran in 1908, after which Abadan and Khorramshahr grew rapidly. By the 1930s the two cities were connected to Tehran by air, rail, and road routes. Khorramshahr was captured by Iraq during the opening weeks of the western backed Iraqi invasion of Iran (1980-1988), and occupied until 1982. The city was devastated during the fighting, as was Abadan.
By the end of the war, Khorramshahr had been completely decimated by Saddam Hussein"s forces, with very few buildings left intact.
In the third year of war, ‘Beytol Moqaddas Operation’, (on Khordad 3rd 1361), resulted in the liberation of the important and strategic port of Khorramshahr from the clutches of Iraqi aggressive forces.

On Sep, 22, 1980 Iraq attacked Iran at a time when Iran was least prepared for a war. The Iraqi army supported by western and Arab countries advanced into Iran capturing Khorramshahr and Susangerd and stopped near Ahvaz. Abadan became under siege and was about to collapse when it was suddenly freed through courageous and daring operations by Iranians.
After that, Iran inflicted one defeat after another on the Iraqi army and Khorramshahr was freed after two years, on May, 24, 1982. But the devastating war lasted for 8 years with more than 1,000,000 casualties on each side according to some sources.
About 19,000 Iraqi soldiers were taken prisoner after liberation of Khorramshahr which was occupied for 578 days. During the Beytolmoghaddas Operation 6,000 Iranian soldiers were killed and 24,000 were injured.
