The battle of Transfex Iridius

Slippery and Ancient
The battle of Transfex Iridius occurred as the Covenant fleet of Righteous Power, consisting of 12 ships, engaged the Paris-Class UNSC Frigate "Slippery" and the Marathon-Class UNSC Cruiser "Ancient", the battle lasted for 4 hours, the slippery was lost with most of it's crew, evac pods were shot down so ODST Pods were used to drop onto Beta Gabriel, which the slippery was currently above, a ODST Team and a spartan were able to get off safely, the Ancient survived the battle, it's kills were astounding since it took out over half of the fleet, and in the process, wasn't destroyed
