Yes. Which the Solars inevitably lost. I mean, they fought, sure, but they were never going to win. "To make a fight of it" implies that the outcome was ever in doubt, and it wasn't. If the Usurpation was going to be averted, it would have to happen prior to the Calibration Feast.
If a combat-specced Solar goes up against a Usurpation Sidereal/DB kill-team, the Solar dies. Period. They die like a little bitch. They die face down in the mud, wailing incoherent questions like "why?" and "who?" and "how does my hair hurt?"
The ones that made a fight of it? Those were the ones who died after the initial decapitating strike, because they didn't attend the Calibration Feast and remained holed up in their own cities, with their superweapons and fortresses and armies, which frequently included Dragonblooded loyal to them.
