Yeah, we had a victory of sorts. My science officer, Doc Lee, is my least capable fighter. He's better at support but that wasn't really this type of encounter. After a protracted time shooting probes finally encountered Donatra and defeated him. Burned through all my minor and most of my major components. Accumilated zero loot (really - I went through the logs twice to verify).
So although it was good to participate in a fleet event, I'll be holding off for now. At least until I get Doc Lee and the remainder of my characters through Operation Gamma and the rest of the FE.
