Zahavan Civil War

The Zahavan Civil War was a conflict fought between the Primogenitor Argentius Vairosean and his Uncle Demoleon, who had claimed his throne. The war grew to include numerous localized rebellions against imperial authority, and later an attempted social revolution by the Cult of ______.

Background
The Zahavan civil war was was the culmination of the instability generated by a series of short lived, and inept Primogenitors whom had passed increasingly unpopular decrees. By the time Argentius became Primogenitor in 1917, he was the fifth such person to be named Primogenitor since 1913. The untimely deaths of his predecessors, coupled with their inept leadership had led to a growing national weariness in Imperial authority, and Zahavan faith as a whole. Only a year into his reign, Argentius' uncle, Demoleon declared himself rightful Primogenitor, and claimed the throne for himself. Following his claim to the throne, several legions, namely those lead by his sons declared their support for Demoleon's claim to the throne while other legions swore their loyalty to the crowned Primogenitor.

Members of the Rehati, and the Megas Syndriot, as well as several other relatives attempted to mediate between Argentius and his Uncle throughout 1917 and 1918, with an uneasy peace existing between the Primogenitor and his Uncle during this time. Ultimately, however negotiations broke down, and battle ensued between the two in November 1919 CE.

Hostilities begin
After over two years of attempted negotiations Demoleon, believing his position to be strong enough for a quick victory dispatched a force of some 40,000 troops under command of his son Stefanos, to attack imperial forces camped outside town of Nakhmas. The Imperial commander, Tetrach Tullus Numerius with 26,540 thousand men were under the impression that the latest round of negotiations would not conclude until the following day and were taken by surprise.

The resulting battle saw Stefanos' army suffer light casualties, while Numerius' force was annihilated, with some 11,350 killed, 8,438 captured, and 4,760 wounded or missing. Even more damaging than the loss of Numerius' force was that now Argentius' left wing was outflanked forcing him to withdraw south across the Nefertari river. This maneuver left a clear path towards the capital Arcanium, where Argentius' was forced to leave only a small garrison whose numbers were bolstered by naval infantry from the Imperial fleet. The political ramifications of the reigning Primogenitor abandoning the capital bolstered Demoleon's position and would have more disastrous affects for Argentius in the years to come.

First battle of Thraxia
The early and decisive victory coupled with the now seemingly clear path to the capital emboldened Demoleon who split his forces in two, Two legions would pursue Argentius' forces across the Nefertari, while the remainder of his force would march on Arcanium and begin a siege. Demoleon placed Aulus Sallustius as commander for the forces sent to peruse Argentius.

The two forces would meet at the town of Thraxia, which was an important railway hub, and one of the few areas where a substantial crossing of the Nefertari already existed. Sallustius had been slowed on his march south by bands of loyalist Praecep frontier troops, allowing Argentius' forces time to prepare defenses. The following battle saw bloodletting likely never before seen on the Avalonian continent. Sallustius' troops advanced over largely open ground and despite a continual bombardment lasting over 6 hours the defenders had remained steadfast in their fortified positions resulting in substantial casualties for the attackers.

After the fourth attack had not only been repulsed but had actually lost the positions previous attacks had taken on the town outskirts, Sallustius pulled his forces back and began to make defense works of his own. The slow static fighting around Thraxia would continue for the rest of the year and into 1920.

Siege of Arcanium
With Argentius' forced pinned down to the south Demoleon proceeded to march on the capital virtually unopposed and in January of 1920 laid siege to the city itself. Initially Demoleon believed the city would capitulate quickly, with his intelligence reporting their was a skeleton garrison of only four to six thousand men. In reality the garrison, which had been bolstered by Praecep frontier troops, academy cadets, and left behind Ordo Hetaeri guards with naval infantry was closer to 18,000 men. Still much smaller than the 178,000 Demoleon had under his command.

While the siege could have been, and perhaps should have been a knockout blow and victory for Demoleon, it turned out to be one of his greatest miscalculations which resulted in his ultimate defeat. From the beginning the siege was ineffective, the weather was poor, making conditions for Demoleon's troops difficult to conduct maneuvers or to construct siege trenches. Another overlooked issue was the fact that Demoleon's forces had virtually no naval presence nearby, allowing the city to continue to receive supplies, and the loyalist ships in harbor would routinely shell Demoleon's forces whenever they attempted to move. Lastly, Demoleon was so fixated on taking the capital, he repeatedly refused requests from Sallustius for more troops to break the stalemate around Thraxia to the south.

Still the mere fact that the capital city was under threat, and the reigning Primogenitor had fled caused significant political pressure on Argentius, and in fact there were calls by some for him to abdicate. Additionally there were a number of defections to Demoleon's side by some army troops.

Battle of Helios Bay
While the vast majority of the Nautika remained loyal to the Primogenitor elements of the third flotilla defected to Demoleon following the announcement that Arcanium was besieged. This provided Demoleon's forces with an opportunity to fully envelop the capital, and increase the pressure on Argentius further. Demoleon issued orders for the flotilla to steam for Helios Bay immediately under Admiral Cominius Megadates.

The loyalist forces under Admiral Hieronymus Kyrios uncovered the pretender plans due to loyalist elements within the third flotilla, with their plans revealed Kyrios laid a trap for the pretender ships, steaming most of his ships away while leaving only one armored cruiser in the bay with several destroyers while the bulk of his forces steamed out to sea. When the pretender forces arrived, Megadates assumed the remainder of the loyalist fleet was docked in the harbor and commenced his attack. The larger pretender force was able to easily brush aside the rear guard loyalist fleet and maneuvered to begin a blockade of the city harbor.

Megadates ordered his ships to begin taking out the cities coastal harbor batteries which were now firing upon them, with his fleet arrayed to bombard the harbor defenses Megadates had left his ships as prime targets for Kyrios' arriving fleet. Pinned between the harbor, and the arriving loyalist fleet Megadates ships were picked off one by one, until with his own flagship reduced to a burning hulk, Megadates issued the order to surrender shortly before taking his own life.

The defeat of the third flotilla ensured Arcanium could not be completely enveloped, the victory at Helios Bay also gave Argentius and the loyalist cause a much needed political boost. Additionally it forced Demoleon to make a decision, either attempt to assault the city outright, or lift the siege and attempt to defeat Argentius in the field. With summer already approaching the window for any meaningful campaign season would be closing rapidly.
