Saragarhi existed for one reason: Fort Lockhart and Fort Gulistan could not see each other. The two British-held forts, originally built by Maharaja Ranjit Singh during the era of the Sikh Empire, sat on the Samana and Sulaiman Ranges of the Hindu Kush mountains, separated by miles of rugged terrain. Saragarhi was established midway between them as a heliographic relay station -- a small blockhouse on a rocky ridge with loop-holed ramparts and a signaling tower, designed to bounce flashes of mirrored sunlight between the two garrisons. In August 1897, five companies of the 36th Sikhs under Lieutenant Colonel John Haughton were stationed across the Samana Hills to hold this volatile stretch of the North-West Frontier. The 36th Sikhs, created in 1894 under Colonel J. Cook, were composed entirely of Jat Sikhs. Tribal Pashtun uprisings had been escalating throughout the summer, and on September 3 and 9, Afridi tribesmen attacked Fort Gulistan. Both assaults were repulsed. A relief column reinforced Saragarhi's garrison to twenty-one men -- three non-commissioned officers and eighteen soldiers.

On the morning of September 12, observers at Fort Lockhart saw an enormous force of Orakzai and Afridi tribesmen massing near Gogra and Samana Suk, cutting Saragarhi off from both forts. Thousands converged on the small outpost. Havildar Ishar Singh organized the defense, and the twenty-one soldiers opened fire from behind their loop-holed walls. The Afghans carried both original and locally copied Martini-Henry rifles -- the gunsmiths of the Adam Khel Afridi clan near the Khyber Pass had been reproducing British service weapons for decades. The attackers breached the outer wall, but the defenders fell back to the inner defenses and fought room by room. Some of the soldiers who died had moved forward to search approaching tribesmen under a flag of truce; others fell at their posts. Through it all, Sepoy Gurmukh Singh continued flashing his heliograph reports to Fort Lockhart. His final signal requested permission to fix bayonets and charge. He then set fire to the outpost's stores and fought until he was killed.

The defenders of Saragarhi did not die for nothing. By holding the outpost for hours against overwhelming numbers, they delayed the Afghan advance long enough for reinforcements to reach Fort Gulistan on the night of September 13-14, before the tribesmen could capture it. The strategic calculation was brutal but effective: twenty-one lives spent to save a fort and, potentially, the entire Samana position. When British forces retook the ruins of Saragarhi on September 14 using intensive artillery fire, they found approximately 600 bodies around the destroyed post. The total casualties across the broader Tirah Campaign reached some 4,800. The burnt bricks of the outpost were gathered and shaped into an obelisk honoring the fallen soldiers.

All twenty-one soldiers were posthumously awarded the Indian Order of Merit, the highest gallantry award available to Indian soldiers at the time -- the equivalent of the Victoria Cross, or today's Param Vir Chakra. The men hailed from the Majha region of Punjab. To honor their sacrifice, the British built two Saragarhi Gurdwaras: one in Amritsar, near the Golden Temple's main entrance, and another in Firozpur Cantonment, the district many of the soldiers called home. The Indian Army's Sikh Regiment commemorates September 12 as Saragarhi Day every year. In 2021, a ten-foot bronze statue of Havildar Ishar Singh, funded by donations totaling 100,000 pounds from the local Sikh community, was unveiled in Wolverhampton, England. The battle has inspired the epic poem Khalsa Bahadur, the 2019 Bollywood film Kesari starring Akshay Kumar, and a television series. Often compared to the Battle of Thermopylae, Saragarhi endures because it asks a question every generation must answer: what would you die to defend?
