[1] In late November, the Iranians decided to respond to the Iraqi destruction of the Abadan Refinery by neutralizing the Kohr al-Amaya and Mina al-Bakr offshore oil terminals.

[1] During the night of 28 November, six ships of the Islamic Republic of Iran Navy's Task Force 421 deployed Iranian marines on the Iraqi oil terminals at Mina al Bakr and Khor-al-Amaya.

The marines, supported by Army Aviation's AH-1J Cobras, Bell 214s and CH-47C Chinooks, eliminated most Iraqi defenders during a short firefight, then deployed a large number of bombs and mines.

[1] At the same time, two Iranian Kaman-class (La Combattante II type) missile boats (Paykan and Joshan) blockaded the ports of Al Faw and Umm Qasr, blocking 60 foreign ships and shelling both facilities.

[1] At this time, the Iranian F-14 Tomcat formations joined the battle and, together with several F-4s, covered the withdrawal of Task Force 421 and bombed the Iraqi oil rigs.
