- Bakkin said "all our efforts were in vain" , and she believed at least , that WB's estate/treasure was still on Sphinx ( she asked Marco to hand it over to her ) .
And as far as i know the village & villagers were safe also ( Marco also said the village was saved ) , so she wasn't talking about them either .
So it looks to me what she meant by "our efforts were in vain" was that at least she & Weevil didn't stand a chance vs the Green Beast .
- As for Bakkin not being captured , idk why Marines didn't capture her , but there was a frame showing her shouting "Weevil" who was sailing away from her on GreenBeast's Marine Battleship , and Weevil shouted back "Mama!" .
So Marines knew she was there . But of course GB wasn't needed to capture her , some VA some RA some fodder Marines could've made her submit .
- Weevil giving in would mean he knew he didn't stand a chance vs the Green Admiral .
Unless you're thinking Weevil gave in because GB had hostage(s) , which would be an assumption based on flimsy arguments .
Why didn't Bakkin mention it if GB had hostage(s) with him ? .
