1st Battle of Riseri

Overview
The First Battle of Riseri is the only space battle of the War of Volatilis Subjugation. It involved a Manta fleet comprised of every military vessel they had except FFZ-001 and FFZ-002, against every military vessel in the fleet of the Sisterhood of Esskal. While a number of Vaalo warriors died in their boarding attempts, no Manta spacecraft were lost, and the war ended with the Mantas in possession of the Volatilis fleet, the Riseri star system, and by default the Lorai system since it could no longer be defended.

Battle
From scouting actions, the Mantas had discovered that the Sisterhood of Esskal would be putting its fleet through a general maintenance overhaul, leaving them vulnerable to invasion. However, the time window would be short after arrival, as the Volatilis spacecraft were not incapable of fighting if they could leave their spacedocks. The Dependable class freighters had been converted into basic transports, with only enough life support for a one-way trip.

After reaching Riseri, the fleet spent a short time assessing the situation. DDZ-001, FFZ-003, AKFZ-001 and AKFZ-002 made tactical jumps to the spaceyards containing the Kalros class destroyers. They immediately opened fire on the destroyers, taking out surface systems like sensors, communications and point defenses.

The freighters docked with the spaceyards, emptying their cargo bays of the Vaalo warriors. The warriors captured a spaceyard within fifteen minutes, quickly followed by the other station. The destroyers were boarded soon after that, and Vandal launched a shuttle carrying prize crews.

LFZ-001 announced it was being overwhelmed by the Volatilis frigates it had been sent to subdue, so when the freighters reported all Vaalo warriors had disembarked, the order was sent for the freighters to reinforce LFZ-001. The freighters were successful in backing up LFZ-001, driving the frigates out of attack range. At this time, a Volatilis destroyer contacted FFZ-003 to announce its surrender, and shortly afterwards a report from the Vaalo boarders announced that they had taken key points in the other destroyer.

Vandal launched multiple salvos of five missiles, destroying two Volatilis frigates and forcing a third to surrender. The prize crews taking command of both destroyers marked the victory of Manta forces in the system. In the face of Manta orbital superiority, the Sisterhood of Esskal's government surrendered.

Aftermath
This battle set the stage for the later rebellion by the people of Lyesul against Manta rule, which resulted in the Volatilis population being decimated through an orbital bombardment.
