Main Universe Batman had already understood why the other side had released Hulk first. They wanted Martian Hunter's Mind Invasion to push Hulk into his strongest state as quickly as possible, then send him to support Asgard.
Although the base was surrounded, it was only superheroes and some Parademons. This force was far inferior to an invasion by two empires working together.
