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.

The battle was particularly brutal in the history of urban conflict, with most of the capital's outer districts left in ruin from heavy clashes and artillery strikes. Kandsonian forces lost more than 9,800 troops, while the EUEEN lost 3,804, more than all its combined military deaths in previous conflicts since the World War, including the 1999-2005 Vulkaria War. Rettoa and its allies lost around 20,000 soldiers. As a result of the battle, nearly 19,000 civilians died and nearly half of the city's population fled the capital.
