The Battle of Khorramshahr was a significant conflict during the Iran-Iraq War, which lasted from September 1980 to May 1982. It began in October 1980 when Iraqi forces invaded the Iranian city of Khorramshahr. The battle was marked by intense urban warfare, with Iranian defenders putting up fierce resistance against the better-equipped Iraqi military. After weeks of fighting, Iraqi forces captured Khorramshahr in late November 1980. The battle resulted in heavy casualties on both sides and became a symbol of Iranian resilience. The loss of the city was a major setback for Iran, but it also galvanized national unity and determination to continue the fight against Iraq.
