Siege of Abadan  1981

Iraq-Iran War

Following failure at Susangerd, Iran’s Mullahs  overthrew President and Army Chief Beni-Sadr and launched a massive counter-offensive
to break the siege of Abadan. While Iran suffered terrible losses, the Iraqis were unwilling to sacrifice their army against ‘‘human wave’’ attacks
and retreated across the Karun, leaving about 35,000 men to hold nearby Khorramshahr (26–29 September 1981).
