Perses Crisis

The Perses Crisis was a 15-day between Modrovia and Tiperyn in 1974 over the divided Perses Island Chain in the Eurybian Sea.

The crisis began on 4 February 1974 when Tiperyn launched an invasion of a lightly defended, Modrovian island in the Perses Island Chain. Both Tiperyn and Modrovia had administered the island chain separately in relatively peace since the 1500s, but the geopolitical situation in the late 20th century had positioned the two powers as rivals in the Eurybian. Tiperyn had asserted a claim over the entirety of the Perses Island Chain briefly, citing early maps of the islands by Tiperyn explorers, albeit without legal justification. The Perses Crisis was the culmination of two decades of clashes between the two countries in the Eurybian that began with a series of naval battles concurrent with the Great Kesh War. It involved several marine battalions and naval and air assets on both sides, although there were few casualties and the conflict did not expand to involve either the North-South Concordant or League of Free Nations of which Tiperyn and Modrovia were members of respectively. In total, 33 Tiperyn servicemembers and 23 Modrovians were killed during the crisis.

Immediately prior to the conflict the Tiperyn Realm Armada had secured a corridor its Perses Naval Air Station on the island of Crius and targeted Modrovian-held islands in the chain. The Modrovian military made several attempts to break the cordon with naval and air assets. Although Tiperyn lost one corvette in one such engagement, Modrovia failed to sever Tiperyn's line to landed ground troops in the chain. Both states made multiple opposed and unopposed landings of armored, mechanized, and light marine forces, leading to multiple skirmishes and one major battle before Tiperyn withdrew its forces from the island, returning the chain to the status quo.

Although Tiperyn and Modrovia remain geopolitical rivals in the Eurybian region, the two states regained practical and positive relations shortly after Modrovia's departure from the League of Free Nations in 1983. Tiperyn withdrew its claim of sovereignty over the Modrovian-held parts of the Perses Island Chain in 1981 and confrontations in the area of Perses became largely restricted to measuring air defense response times.

Tiperyn order of battle
In the lead up to the invasion of the Modrovian Perses, the Realm Armada mobilized and transferred an Amphibious Landing Group, reinforced Fleet Carrier Group and Destroyer Group to the Eurybian Sea Division for the operation. A Carrier Air Group, consisting of fighters, bombers, and electronic warfare aircraft, was also attached to the Fleet Carrier Group to aid in the defense of the Amphibious Landing Group. An additional Carrier Air Group was garrisoned at the Perses Naval Air Station to contribute to the air effort. Meanwhile, the 2nd Marine Strike Brigade was partially mobilized and set sail with the Amphibious Landing Group, with one-third of the brigade taking part in the initial invasion with the remainder being held in reserve.
