Current Luffy, Zoro, Sanji, WCI Jinbe, Robin, Nami with Zeus, Brook, Franky and Chopper

Cavendish (he has complete control over Hakuba), Bartholomeo, Sai, Leo, Hajrudin, Ideo, and Orlumbus.

The Escaped Convicts such as Crocodile, Buggy and his followers are present too to help Luffy to release Ace.

Squardo isn't going to betray Newgate.

Whitebeard is old, but he's not ill.

They has 3 hours prep and basic information about Marine tactics

But Shanks didn't come to help this time he was busy fighting Kaido.

they get ace back a lot easier as WB is not injured and luffy is much stronger

Literally all the fodder on the island get soloed by law, the M3 and law as well as marco could probably beat a admiral or at least stalemate for a while whilst WB goes on a rampage

after a lot of casualties i think ace will be free but will not die Wb will lay his life on the line for the others.

When BB comes it will get interesting but after seeing all the sacrifices i'm sure Ace would escape in laws sub with the SH whilst the others leave on their ships.
