Why does Jim bring Hands his brandy

I think Jim is wanting to use Hands to be on his side. Jim finally finds brandy for Hands, as well as biscuit, cheese, and fruit for himself. Returning to the deck, Jim drinks water and gives Hands the brandy. Jim tells Hands that he is taking possession of the ship and should be regarded as captain, and with that pronouncement, the boy pulls down the pirates' flag.
