The '''Battle of Osmino''' was part of the [[Osmino]] offensive in the [[Roca War|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 [[Sateroc]]ean 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 (Iearth)|World War]], including the [[Second War in Vulkaria|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. 

==First assaults==
Beginning on the morning of October 13th 2024, Rettoan forces and their partnering [[Sateroc]]ean armored columns and [[Brotherhood of Kolkesburg]] militia units began a ground and air assault on Osmino from staging points in [[Solime]] and [[Arastaoir]]. This coincided with a massive rocket barrage against the capital, with short-range missiles from all surrounded directions in occupied Kandson, as well as cruise missiles from Rettoan naval ships, and medium and long-range ballistic missiles from Rettoa, [[Stasso]], and mainland [[Sateroc]]. 

Rettoa apparently intended to rapidly seize Osmino, with special forces infiltrating the city, supported by airborne operations and a rapid mechanised advance from the north and west. Military commanders had aimed to attempt an approach from the south as well, but heavy resistance in [[Dalir]] prevented the establishment of a southern front. 

Initial attacks were successful despite stubborn resistance from defending Kandsonian soldiers and armed civilians. Kandsonian use of sophisticated man-portable weapons provided by international allies, however, slowed the ground assault and much of the fighting stalled to the satellite districts of Osmino rather than the city interior itself.

===Capture of Senell Airport===
Rettoan forces began a "concerted effort" to take [[Senell International Airport]] in the first day of the assault on Osmino. Around 5:05 in the morning amid wider rocket attacks on the capital, Rettoan forces began to establish positions in tower blocks overlooking the airport, including a medical station, staging area, and an artillery observation post. At 06:15, Rettoan forces began to barrage the airport with Grad rocket fire, using their positions in neighboring residential buildings to direct artillery fire at the airport.

A formation of 20 to 34 Rettoan helicopters launched the operation to secure Senell Airport to create an airbridge in which troops and equipment could muster less than 10 kilometres (6.2 mi) from Osmino. To cover their attack on the airport, the Rettoan military jammed Kandsonian radars and suppressing local air defense sites. Flying low, the Rettoan helicopters made their approach from the [[Sarits River]] and were immediately attacked by Kandsonian small arms fire and MANPADS. The Rettoan helicopters countered by deploying flares. Several were hit, with at least two helicopters being shot down and several more aborting their landings.

As the Rettoan paratroopers landed in growing numbers and fanned out, [[Brotherhood of Kolkesburg]] units arrived in armored trucks and disembarked closer to the main terminal supported by three Rettoan tanks, and the Kandsonian defending garrison was forced to retreat as they started to run out of ammunition. At one point during the fighting, a helicopter was shot down and crashed into the main terminal, erupting a massive fire that engulfed most of the Arrivals building. The initial clashed had lasted about an hour; the paratroopers had suffered significant losses, while the Brotherhood militia also suffered high casualties but were able to push Kandsonian fighters out of the terminal. The Rettoan forces were thus able to secure the airport.

Attempts by Kandsonian forces to take the airport back in the following day were thwarted numerous times as Rettoa and its allies began encircling the city and thus the counter attackers.

===Recapture of Senell Airport===
By 30 October, the airport's runways and main hangers had been far too damaged by artillery and airstrikes to be utilized by Rettoan forces, and frequent clashes nearby rendered any aircraft attempting to take off from the airport to be vulnerable to surface fire. The beginning withdrawal of Rettoan forces from Osmino culminated in a staging of retreating forces at Senell, a strategic failure which allowed Zamastanian [[Z-17 Condor]]s to target vehicles on and around the runways. On 31 October, a EUEEN ground attack consisting of [[Odoni]], [[Blallia]]n, and [[Vœyetska]]n units entered the airport and seized the runway with little resistance. However, the main terminal of the airport was heavily defended by remaining Rettoan forces, and clashes became close-quarters and deadly. Additionally, booby-trapped staircases and hallways led to over four dozen casualties among EUEEN troops as they maneuvered through the structures.
