Babur had spent most of his life fighting to hold onto things and failing. Born in 1483 in the Fergana Valley of modern Uzbekistan, he inherited a small kingdom at age eleven and lost it almost immediately to rival warlords. He captured Samarkand twice and was expelled both times. In 1504, he seized Kabul and Ghazni from the Arghun warlord Mukim Beg -- his paternal uncle Ulugh Beg II had died in 1501, leaving a power vacuum the Arghuns filled -- finally securing a base of operations. But Kabul was a mountain outpost, not the center of power he craved. Blocked to the northwest by the Uzbek warlord Muhammad Shaybani, Babur turned his ambitions southeast, toward the rich plains of Punjab and the crumbling Delhi Sultanate beyond. He began probing raids across the Indus as early as 1519, reaching the Chenab River. By 1524, he had taken Lahore, Sialkot, and several other cities before withdrawing to Kabul. It was preparation, not conquest. Babur was learning the terrain.

Babur's opportunity came from inside the enemy's house. Ibrahim Lodi, the Sultan of Delhi, was locked in power struggles with his own nobles and relatives. Daulat Khan Lodi, the governor of Punjab, defected to Babur and invited him to invade -- a decision born of political desperation rather than loyalty. At the end of 1525, Babur crossed the Indus in December with roughly 12,000 soldiers, many of them seasoned Central Asian veterans. After securing Punjab, he advanced toward Delhi. Ibrahim mustered a vast army -- contemporary sources estimate between 50,000 and 70,000 troops, plus a thousand war elephants -- and marched north to meet the invader. The two forces converged at Panipat, a dusty market town about 90 kilometers north of Delhi that sat astride the main road from the northwest. It was not the last time Panipat would decide who ruled India.

Babur's tactical genius lay in understanding what his small force could do that Ibrahim's large one could not. He chained 700 wagons together in a long defensive line, with breastworks for musketeers positioned between every second wagon. At several points he left gaps 150 riders wide -- sally ports from which his cavalry could charge. His right flank was anchored against the town of Panipat itself; on his left, he dug a trench and filled it with cut branches to block enemy horsemen. The position was essentially a fortress built in a morning. Ibrahim had numbers, elephants, and traditional cavalry. Babur had matchlock muskets and cannons -- weapons that most of Ibrahim's army had never encountered. When the sultan's forces attacked, they funneled into the narrow frontage Babur had prepared. Cannon and musket fire pinned their center while mounted archers -- the classic Central Asian weapon -- swept around to harry the flanks and rear.

War elephants had dominated Indian battlefields for centuries. Armored, towering, carrying archers and spearmen on their backs, they were living siege engines that could crush infantry formations and terrify horses. But elephants had never faced gunpowder. When Babur's cannons fired, the noise and smoke sent the great animals into a frenzy. They stampeded backward through their own lines, trampling the soldiers they were meant to protect. Ibrahim's army, already compressed into a killing zone, dissolved into chaos. The sultan himself fought and died in the melee -- one of roughly 20,000 casualties on his side. Thousands more were killed in the retreat. Babur's losses were comparatively light. The battle lasted only a few hours. Its consequences would last centuries.

Panipat gave Babur Delhi and much of northern India, but it did not give him peace. He still had to defeat the Rajput confederacy of Rana Sanga at the Battle of Khanwa in 1527 and the eastern Afghan chiefs at the Battle of Ghaghra in 1529 before his hold was secure. He died in 1530, just four years after Panipat, but the dynasty he founded -- the Mughals, named for their Mongol ancestry -- would rule the Indian subcontinent for over two hundred years. Under Babur's grandson Akbar, the empire became one of the wealthiest and most culturally sophisticated states on earth. Today the battlefield at Panipat is largely absorbed into the modern city. The flat ground that once held 700 chained wagons and a thousand panicked elephants is now urban sprawl and farmland. But the battle's echo persists in every Mughal monument from the Taj Mahal to the Red Fort -- structures built by the dynasty that began with a prince, a few cannons, and a gamble on a dusty Haryana plain.
