@argothair It depends on which battles failed.
Typically, if any battle is going to go sideways, it’s the SZ12 one (DD/CR off of Gibraltar). I don’t mind losing/drawing this one too much, as all does is gives UK an opportunity to either go all-in against the Italian fleet or consolidate their Atlantic Fleet (which Germany really has no means of stopping even if you kill everything).
In the extremely unlikely event that SZ2 or SZ6 (where the actual transports are) go badly, you’re probably in really horrible shape. Only real recourse at that point is to turtle up, by tons of INF, and pray for better luck on Japan’s side of the board.
