The Riamese Invasion of the Unhak was a short undeclared military confrontation between Hoterallia and Riamo in the Unhak Islands Chain. It was dominated by land battles between Riamese army units and the Imperial Hoterallian Army, with minor skirmishes at the beginning of the invasion between the Riamese army units and the Hoterallian Northern Expeditionary Army Group.

The Riamese had air and naval supremacy from the opening days of the invasion, allowing for a fruitful logistics network to exist from the first day of the operation, and ultimately giving the Riamese enough momentum to break through heavily fortified local defenses.

The operation is notable for the Hoterallian use of bicycle infantry, which allowed troops to carry more equipment and swiftly move through thick jungle terrain. The Riamese units, equipped with demolition charges, destroyed over a hundred bridges during the retreat, yet this did little to delay the Hoterallian. With swift movements, the Hoterallian 45th Infantry Regiment delayed the Riamese long enough for the 32nd Division to evacuate the island chain.

After the invasion, the Riamese resumed control of their previously owned territories and several islands that the Hoterallian lost during the invasion.

Background

Hoterallia

By 1940, Hoterallia had been on its downfall politically as the Empire was entering into a state of civil war.[4] Due to the political turmoil, the Empire was forced to withdraw all of its troops from outside the mainland to return home and reunify the homeland.[5] One of the forces that got withdrawn was the 32nd Division and its mixed brigades guarding the Unhak Islands Chain.

The island chain had been under the attention of both the Hoterallian and Riamese due to its geographical location and bountiful natural resources.[3] The islands had been under the Hoterallian influences since the late 1800s after the Hoterallian campaign to capture the chain.[3] Shortly after the Great War, the chain was split between the Riamese and Hoterallian but the Riamese was still bitter about the defeat during the Great War so plans to reinvade the chain were made. This troop build-up was noticed by the Hoterallians, so an immediate evacuation was given to the 32nd Division, and plans to stall the invading forces were given to the 45th Infantry Regiment.[5]

As the Riamese started to invade, the Hoterallian had over 100 tanks, many of which were light tanks and tankettes, these tanks were new models, including the Type 2 Kaminari light tank, Type 90 Kinzoku Kiheitai, Type 2 Raifu tankette and Type 2 Kinma light tank. In addition, they had nearly 150 aircraft available. As well as many well-maintained artillery pieces, anti-tank and anti-aircraft guns, and over 15,000 motor vehicles and bicycles.[5]

Riamo

Aftermath

The invasion would allow the Riamese Navy to hold control to the Unhak Sea, as well as the western entrance to the Nostrian, setting the stage for Riamese dominance of the seas for the next 2 decades.

Furthermore, the conflict became the precedent of a generation-long era of anti-riamese sentiment throughout the archipelago, which made it difficult for Riamo to hold effective control over the islands.
