The Battle of Osmino was part of the Osmino offensive in the Rettoan-led invasion of Kandson for control of Osmino, the capital city of North Kandson, and surrounding districts including Senell International Airport and Cain Air Base. The combatants were elements of the Rettoan Armed Forces supported by Saterocean forces and the Brotherhood of Kolkesburg, with the city defended by the North Kandson Armed Forces supported by the EUEEN and Zamastanian Air Force. The battle lasted from 13 October to 4 November 2024 and ended with the withdrawal of Rettoa and its partnered forces.
Initially, Rettoan forces captured key areas to the north and east of Osmino, leading to international prediction of the city's imminent fall. However, swift intervention by the EUEEN coupled with stiff Kandsonian resistance sapped Rettoan momentum. Poor Rettoan logistics and tactical decisions helped the defenders to thwart efforts at encirclement, and, after a week of protracted fighting, the defending forces began counterattacking.
Following the successful counterattacks in late October, Rettoa began withdrawing its forces from the capital city area on 1 November. Three days later, the Kandsonian authorities declared that Osmino was again under Kandsonian control, and EUEEN forces began pushing beyond the capital.
