The assault on Kediri was a culmination of extensive planning and military logistics involving the Mataram Sultanate's troops and the Dutch East India Company. Trunajaya's rebellion, which had gained momentum in East Java, posed a substantial threat to Mataram's hegemony in the area. The rebellion attracted attention across the archipelago, as it highlighted the struggles for power in a region rife with competing factions and colonial interests. The decision to combine forces was strategic, utilizing Dutch naval power and Mataram’s local knowledge for a coordinated attack.

The allied forces began their march toward Kediri, overcoming challenging terrain and ensuring effective supply lines amid escalating tensions. After enduring significant hardships, such as limited provisions and the logistical hurdles of moving troops, the forces finally reached the stronghold. The assault itself saw clashes that showcased both traditional Javanese combat techniques and European military strategies, with heavy casualties reported on both sides during the conflict.

The capture of Kediri was not just a tactical victory; it was symbolic of the waning influence of Trunajaya and a reinforcement of Mataram's political authority in the region. This event served to consolidate the cooperation between local rulers and colonial powers, while also demonstrating the shifting dynamics of power in Southeast Asia during this period. By securing Kediri, the allies successfully destabilized Trunajaya's support networks, effectively scattering his forces and diminishing his insurrectionist capabilities.
