This is a choice scenario. You can choose a historical path or a fictional one. With a victory you take the historical path. in this case, the 3rd infantry reg. stays at Port Stanley and the battle for Goose Green goes on as it happened historically. If you get a tactical victory, the 3rd infantry reg. marchs towards Goose Green as a reinforcement.
Note: If you choose the fictitional path and you lose, the game will not count on the 3rd infantry reg. untill the end of the campaign.
