Iran The Original Iraqi Offensive
Sources: The Library of Congress Country Studies; CIA World Factbook
As of June 1987, the major events of the war could generally be divided into six overlapping phases: the original Iraqi offensive, Iranian mobilization and resistance, the Iranian counteroffensive, the war of attrition, Iraqi internationalization of the war, and the surge in superpower involvement. In addition, there was the tanker war in the Persian Gulf, which extended over several of these phases.
The Original Iraqi Offensive
Figure 11. Initial Iraqi Attack on Iran, September-November 1980
Baghdad originally planned a quick victory over Tehran. On September 22, 1980, Iraqi fighter aircraft attacked ten air bases in Iran. Their aim was to destroy the Iranian air force on the ground--a lesson learned from the Arab-Israeli June 1967 War. They succeeded in destroying runways and fuel and ammunition depots, but much of Iran's aircraft inventory was left intact. Simultaneously, six Iraqi army divisions entered Iran on three fronts in an initially successful surprise attack. On the northern front, an Iraqi mountain infantry division captured Qasr-e Shirin, a border town in Bakhtaran (formerly known as Kermanshahan) Province, and occupied territory thirty kilometers eastward to the base of the Zagros Mountains. This area was strategically significant because the main Baghdad-Tehran highway traversed it. On the central front, Iraqi forces captured Mehran, on the western plain of the Zagros Mountains in Ilam Province, and pushed eastward to the mountain base. Mehran occupied an important position on the major north-south road, close to the border on the Iranian side. The main thrust of the attack, however, was in the south. Iraqi armored units easily crossed the Shatt al Arab waterway and entered the Iranian province of Khuzestan. While some divisions headed toward Khorramshahr and Abadan, others moved toward Ahvaz, the provincial capital and site of an air base. Supported by heavy artillery fire, the troops made a rapid and significant advance--almost eighty kilometers in the first few days. In the battle for Dezful in Khuzestan, where a major air base is located, the local Iranian army commander requested air support in order to avoid a defeat. President Bani Sadr, therefore, authorized the release from jail of many pilots, some of whom were suspected of still being loyal to the shah. With the increased use of the Iranian air force, the Iraqi progress was somewhat curtailed (see fig. 11).
The last major Iraqi territorial gain took place in early November 1980. On November 3, Iraqi forces reached Abadan but were repulsed by a Pasdaran unit. Even though they surrounded Abadan on three sides and occupied a portion of the city, the Iraqis could not overcome the stiff resistance; sections of the city still under Iranian control were resupplied by boat at night. On November 10, Iraq captured Khorramshahr after a bloody house-to-house fight. The price of this victory was high for both sides, approximately 6,000 casualties for Iraq and even more for Iran.
