From 2D Market:
An original story featuring a female knight heroine.
A lady knight leads her knight company on a punitive campaign to subjugate the local goblin tribe. However, goblins use their greatest weapon, large numbers, to overwhelm the expedition. The entire company, with their leader knocked unconscious, falls into goblin captivity.
Luckily for everyone, goblins don’t practice executing captives, but rather prefer to sell them into slavery.
Soon after, the lady knight regains her conscious to a band of goblins discussing how to appraise their newly captured goods...
