The invasion of the Bengal Sultanate did not begin with a traditional declaration of war or a proud, sunlit march of banners. Instead, it materialized like a silent, overwhelming specter under the absolute cover of a torrential midnight downpour. The sky above the Bengal border had fractured into a relentless deluge, turning the roads into thick, choking mires. Twelve-year-old Crown Prince Vikramaditya Deva, riding at the rear of his vanguard with a cold, analytical stillness, knew the precise tactical value of this miserable weather. Standard matchlock muskets—the absolute mainstay of the Bengal Sultanate's Portuguese-supplied infantry—were rendered entirely useless in such an adverse climate, as their exposed powder pans and glowing match-cords were instantly extinguished by the driving rain.
This stark environmental limitation was precisely why Vikramaditya had chosen this exact night to strike. However, the rapid timeline of the invasion meant that his logistics had not yet permitted a universal weapon upgrade across all units; while the majority of his frontline regiments were equipped with the newly standardized flintlock muskets—which offered far better weather protection than matchlocks due to their enclosed frizzens—only his elite vanguard company carried Chief Weapons Officer Hariharan's newest, highly experimental prize: the percussion cap rifle. Because the percussion cap mechanism was entirely sealed within a copper cylinder and struck directly by an internal, spring-loaded hammer, the torrential downpour had zero effect on its firing capability.
The immediate target was the critical border fortress of Midnapore. Recognizing that a protracted siege in the mud would bleed his resources, Vikramaditya's shadow network, the Tritiya Netra, had already executed a masterstroke of structural sabotage. Embedded agents within the region had spent weeks monitoring the vulnerabilities of a massive upstream stone dam that regulated the regional river. At exactly midnight, using pre-planted charges of high-granulation black powder encased in watertight lead boxes, the operatives blew the primary floodgates apart.
A roaring wall of water tore down the valley, completely inundating the low-lying plains surrounding Midnapore. Crucially, because the stone fortress itself was far too small to shelter the entire regional garrison, the bulk of the Bengal army had been stationed in an extensive, sprawling cantonment camp situated outside the fortress walls, protected only by low earthen breastworks. The flash flood ripped through this external camp with cataclysmic force. Tents were swept away, leather gunpowder pouches were instantly soaked through, and hundreds of panicked soldiers were submerged in the rushing currents.
Driven by blind terror, the drenched survivors abandoned their ruined camps and scrambled frantically toward the fortress. Men clutching useless matchlocks, unstrung bows, and sheathed swords bottlenecked at the narrow outer gates, clawing their way up the slick, exposed stone staircases and ladders to reach the high parapets. They were completely disorganized, rendered effectively weaponless by the water, and starkly visible under the flashes of lightning.
That was the exact moment the Khurda forces stepped out of the dark. Standing shoulder-to-shoulder in their uniform steel cuirasses and helms, the infantry leveled their rifles. They did not fire blindly over stone walls; instead, they targeted the dense, exposed masses of Bengal soldiers trapped on the outside ladders, the narrow bottlenecked walkways, and the open walkways of the parapets where they were desperately trying to assemble without functional ammunition, their swords drawn in a futile gesture of defense.
To clear the high walls and break any residual resistance on the ramparts, Captain Devendra's artillery company unleashed the terrifying power of the Vajrastra and Varshastra rocket batteries. Screaming through the midnight rain, the unique Varshastra rockets—vicious projectiles whose tail ends were tied to sharp swords—descended upon the enemy positions. As they struck down in a wild, erratic manner, the spinning blades sliced through the panicked masses, cutting flesh and creating deep lacerations. Compounding the carnage, the volatile nature of the Varshastra caused many of the rockets to violently explode upon impact, shattering defensive positions alongside the Vajrastra and throwing the defending Bengal archers into the roiling waters below, their useless bows slipping from their fingers.
"Present! Volley fire!" Major General Virendra's voice boomed over the rushing waters.
A continuous, devastating wall of fire tore through the darkness. The elite vanguard's percussion rifles fired with absolute, unbroken reliability, followed closely by the rolling, alternate volleys of the flintlock companies. The enemy, armed only with ruined matchlocks, suppressed archers, and swords that could not close the distance, could not respond with a single ranged shot. They fell like wheat before an industrial reaper as they stood exposed on the slick stone structures. It was a psychological and technological slaughter, proving to the dying Sultanate vanguard that the dawn of a new, industrialized empire had finally arrived on their borders.
