Liberation of Helios

The Liberation of Helios was a battle that took place on the 30th July, 249 after slightly over a year of the city's occupation by Pandrosi Communists, and a blockade cutting off the New World from the Old World.
The battle was the first major participation in the war by the Empire of Kordowyn, her subjects, and the Templari'i Republic and the first instance of a New World military presence in the Old World. 
The Kordynian Allied Fleet joined with the stranded Lirrachan North Fleet, and attacked Helios in their effort to free Emperor Llywelyn I, who had been trapped in the Old World on a State Visit when the Pandrosi seized Helios. As the Coup of '93 lead to the Emperor being taken under house arrest by Supreme Leader of the Gretian Imperial Junta, Hiram Borman, Kordynian forces rallied against the Gretians in order to liberate him, the crew of HMS Maddock, and his daughters.
The fleet caught the Pandrosi off guard, and the new Torpedo Destroyers were very effective in destroying five battleships in port, while the main fleet cut the defending cruisers apart. Pandrosi forces were quickly overwhelmed by the Hereditan Resistance, who turned Pandrosi artillery against the Communist fleet. With the situation turning against them, the Pandrosi fleet turned and ran.
The liberation of the city and re-opening of the Channel leaves the Allied Fleet poised to begin invading Gretia.
