By early 1986, the Iran-Iraq War had ground on for nearly six years. Iran had pushed the Iraqis off its soil back in 1982, but every attempt to invade Iraq and topple Saddam Hussein's government had failed. The problem was straightforward: Iran could no longer replace its losses. International sanctions starved it of spare parts and modern weapons, while Iraq received heavy support from foreign nations eager to prevent an Iranian victory. The front lines barely moved. What Iran lacked in hardware, however, it tried to compensate for with tactical ingenuity. Commanders shifted away from the costly human wave assaults that had defined the war's early years. Thousands of Revolutionary Guard troops trained in amphibious warfare, night fighting, and marsh infiltration. Southern Iraq, with its vast wetlands and meandering waterways, offered terrain where Iraqi armor, artillery, and air power lost their advantages. Iran's planners studied these landscapes carefully and devised a plan to strike where the Iraqis least expected it.

The deception was essential. Iran made it appear the offensive would target Basra, as most previous attacks had. Instead, the real objective lay farther south: the al-Faw peninsula itself. On the night of February 9, commandos crossed the Shatt al-Arab in speedboats while transport helicopters ferried additional troops to landing zones on the far bank. Engineers followed close behind, constructing pontoon bridges across the river to bring heavier forces and supplies. The Iraqi defenders, mostly units of the Iraqi Popular Army rather than professional soldiers, were overwhelmed. By the time Iraq understood the scope of the assault, Iranian forces had dug into positions at the peninsula's tip and captured the main air control and early warning center that monitored the Persian Gulf. The operation had been planned entirely by professional military officers, a mix of regular army and Revolutionary Guards commanders working in rare coordination.

Iraq's response was ferocious. Republican Guard units launched repeated counterattacks throughout February and into March. When conventional assaults failed to dislodge the Iranians, Iraq turned to chemical weapons. But Iran held. The troops who had crossed the river dug in and absorbed every blow, maintaining their foothold on the peninsula despite heavy casualties on both sides. The battle officially ended in a stalemate by March 1986, though sporadic clashes along the front lines would continue for another two years. For Iran, the seizure of al-Faw was a strategic triumph, one of its greatest achievements of the entire war. For Iraq, the loss was a humiliation that damaged the prestige of Saddam Hussein personally and forced a massive buildup of defensive fortifications around Basra, the major city now threatened from the south.

The fall of al-Faw sent shockwaves far beyond the battlefield. Kuwait and Saudi Arabia, alarmed that Iran now sat on the doorstep of the Gulf's western shore, sharply increased their financial and material support for Iraq. The regional balance of power had shifted, and neighboring states scrambled to ensure it shifted back. Iran's hold on the peninsula lasted two years. In April 1988, Iraqi forces launched the Second Battle of al-Faw and recaptured the territory in a swift offensive that signaled Iraq's resurgence in the war's final months. But the strategic calculus had been permanently altered. The first battle demonstrated that Iran could strike at Iraq's most vulnerable point, and the second demonstrated that Iraq had rebuilt enough to take it back. The peninsula changed hands, but the underlying tensions that had driven two nations to fight over a strip of mud and marsh at the edge of the Gulf would persist long after the guns fell silent.
