After Iran's failure in Operation Ramadan, they carried out only a few smaller attacks. Iran launched two limited offensives aimed at reclaiming the Sumar Hills and isolating the Iraqi pocket at Naft shahr at the international border, both of which were part of the disputed territories still under Iraqi occupation. They then aimed to capture the Iraqi border town of Mandali. They planned to take the Iraqis by surprise using Basij militiamen, army helicopters, and some armoured forces, then stretch their defences and possibly break through them to open a road to Baghdad for future exploitation. During Operation Muslim ibn Aqil (1–7 October), Iran recovered of disputed territory straddling the international border and reached the outskirts of Mandali before being stopped by Iraqi helicopter and armoured attacks. During Operation Muharram (1–21 November), the Iranians captured part of the Bayat oilfield with the help of their fighter jets and helicopters, destroying 105 Iraqi tanks, 70 APCs, and 7 planes with few losses. They nearly breached the Iraqi lines but failed to capture Mandali after the Iraqis sent reinforcements, including brand new T-72 tanks, which possessed armour that could not be pierced from the front by Iranian TOW missiles. The Iranian advance was also impeded by heavy rains. 3,500 Iraqis and an unknown number of Iranians died, with only minor gains for Iran.
