For fourteen years after the fall of the Taliban in 2001, no major Afghan city had been lost to the insurgency. Kunduz broke that record on the morning of September 28, 2015, when Taliban fighters advanced from three directions and Afghan government forces, overwhelmed, retreated to the outlying airport. The fall of this northern city -- one of Afghanistan's largest, with a population of roughly 300,000 -- was not just a military setback. It was a signal that the end of the NATO-led ISAF mission, completed the previous year, had left a security vacuum the Afghan army could not fill alone. What followed over the next two weeks was a brutal urban battle, a botched airstrike that destroyed a hospital, and a political reckoning in Kabul.
The Taliban did not take Kunduz in a single stroke. The siege began months earlier, in late April 2015, with an initial assault that prompted Afghan reinforcements and a week-long standoff. By late May, some 3,000 Afghan troops had massed in the area against an estimated 2,000 Taliban fighters, bolstered by militants from the Islamic Movement of Uzbekistan and elements affiliated with ISIS. A Taliban counteroffensive in June pushed fighters into the Char Dara District, just miles from the city center. Throughout July, the insurgents captured surrounding towns and tightened their grip on Kunduz from the south and southeast. The pattern was methodical: isolate the city, cut its supply lines, erode the defenders' morale. By the time the final assault came in September, the Afghan forces inside Kunduz were exhausted and outmaneuvered.
The September 28 assault was swift. Taliban forces struck from three directions simultaneously, and within hours the government troops had abandoned the city for Kunduz Airport on the outskirts. For the first time since 2001, the Taliban flag flew over a provincial capital. Counterattacks began almost immediately -- Afghan forces pushed from the airport toward the city center on September 29, supported by American airstrikes. Anti-Taliban militia leaders and warlords joined the fight. Reinforcements trickled in, but the situation remained precarious; Afghan commanders reportedly planned to abandon their positions if the American special forces advisers pulled back. On October 4, the Taliban claimed to have recaptured most of the city. The following day, Afghan troops mounted a counter-offensive that pushed them back, and the national flag was raised over the governor's residence for the first time since the battle began. On October 13, after fifteen days of heavy fighting, Taliban forces finally withdrew.
In the early hours of October 3, while the battle still raged, a US AC-130 gunship began firing on the Kunduz Trauma Centre, a hospital operated by Medecins Sans Frontieres. The bombardment lasted from 2:08 AM to 3:15 AM local time. Inside were 105 patients and 80 medical staff. MSF personnel contacted military officials during the attack, but the bombing continued for more than thirty minutes after the notification. Forty-two people were killed -- fourteen hospital staff, twenty-four patients, and four patient caretakers. Thirty-seven more were wounded. The trauma center, the only facility of its kind in northeastern Afghanistan, was destroyed. President Barack Obama issued a rare presidential apology on October 7. MSF and the United Nations called for an independent investigation, with the UN condemning the strike as "tragic" and "inexcusable." The incident became one of the most scrutinized US military actions of the entire Afghan war.
Tens of thousands of Kunduz residents fled their homes in the first weeks of fighting. By September 30, at least 30 people -- mostly civilians -- had been confirmed dead, with hospitals treating roughly 340 wounded. By early October, government estimates had risen to 55 dead and 600 injured. A United Nations report later concluded that at least 848 civilians were killed or wounded as a consequence of the Taliban attack and the subsequent fighting. Behind these numbers were families who lost everything: homes looted or destroyed, businesses shuttered, children pulled from schools that would not reopen for months. The displacement was not temporary for many. Kunduz would face another Taliban assault in 2016, and the cycle of violence in the province would continue for years.
The fall of Kunduz arrived in the first year after the end of the ISAF combat mission, and it exposed uncomfortable truths. Afghan security forces, despite years of training and billions of dollars in international support, struggled to hold a major city against a determined insurgent assault. President Ashraf Ghani responded by sacking several security officials for neglecting their duties and pledging financial aid to Kunduz victims, but the deeper problems -- corruption, poor coordination, dependence on foreign air power -- persisted. The battle demonstrated that the Taliban remained capable of seizing urban territory, even if they could not hold it indefinitely. It foreshadowed the far larger collapse that would come six years later, when the Taliban swept through the entire country in August 2021. Kunduz was a warning that went largely unheeded.

Kunduz Airport (OAUZ) lies on the city's eastern outskirts and served as the government's fallback position during the battle. Mazar-i-Sharif (OAMS) is roughly 150km to the west. The city is visible from altitude as a dense urban area amid irrigated farmland. Best viewed at 10,000-15,000 ft.
