The Battle of Meligalas was an essential confrontation occurring in the context of World War II in Greece, where local resistance forces were increasingly entangled in conflicts with collaborationist groups. The Greek People's Liberation Army (ELAS), the military wing of the National Liberation Front (EAM), aimed to drive out German occupiers and prevent the consolidation of collaborationist forces within Greece. The security battalions were formed under the leadership of the collaborationist government, consisting of individuals loyal to Nazi Germany, complicating the already volatile political atmosphere in the country.

The battle itself took place in the town of Meligalas, which became a focal point for the clash between ELAS and the collaborationists. The fighting was marked by fierce skirmishes, where each side sought to establish dominance over the region amidst the waning influence of German forces. The ELAS, drawing on local support and popular sentiment against the occupiers, fought not only for military victory but also for legitimacy as the rightful representatives of the Greek people.

As ELAS forces advanced, they encountered significant resistance from the security battalions, leading to a protracted struggle characterized by brutal combat. The eventual outcome significantly impacted the balance of power among Greek factions, as well as the broader resistance movement against both German occupation and local collaborationist forces. The battle was part of a larger narrative of civil strife and guerilla warfare that would continue in its aftermath, leading toward the eventual Greek Civil War.
