The battle from that point on got very ugly. We finally managed to swing the Dauntless about and savaged the ship with a broadside, dealing 30+ damage to the Eldar ship, however it immediately returned fire, pulsar lances and battery fire savaging our hull, dropping us to under 50% hull integrity, fully half the crew was killed, over 20,000 men lost. Desperate and not really thinking things through, I finished coming about and aimed the Dauntless straight at the Eldar Dragon, Ramming Speed, TPK time!
The Daunltess speared the Xenos vessel, dealing two-dozen points of damage and shattering the vessel's spine. The Emperor was with us, because our vessel only took a single point of damage from the ram. However the Dragon ship's attack craft relauched and further bit into the Dauntless' hull, reducing the ship to just above crippled status and killing even more crewmen. As the two burning ships drifted apart I was sure we'd die due to another attack craft wave, but suddenly Las-battery fire rakes the Dragonship once more as our frigate re-arrives on the field of battle, disobeying my orders for the NPC captain to disengage no matter what happened. The day won thanks to this blatant disregard for my orders, I could not blame him, I would have done the same!
End result, Dragon ship destroyed, Dauntless at 16% hull integrity and a skeleton crew (12%), the Sword Frigate at 40% hull integrity and 42% crew. A close, desperate battle against a superior opponent, won only through crazed gambit. Holofields suck, surprised we succeeded the ram despite them (we roll openly too, no fudging there!).
