Failure Mode by Craig Alanson

When a mission ends in disaster and there is no way to achieve the objective, no way to regroup and try again, no plan B, no hope, all you can do is fall back into FAILURE MODE: try to salvage what you can.

If it is even possible to save anything. Or anyone.

The galaxy is doomed. Monkeys may be clever and too stubborn to give up, but Skippy The Idiot Who Got PLAYED knows the harsh truth: this is a fight he can't win. The odds are not only stacked against him, he was designed not to win this fight.
Maybe he can salvage some faint memory of the civilizations that inhabit the galaxy, but those beings are doomed. Doomed. Including the Merry Band of Pirates.
