What did african americans gain in 1812?

During the war of 1812 many African Americans fought alongside the Americans. Though they were offered freedom for the English many stayed to fight with their country. Even after this though they didn't really gain anything seeing as this didn't end slavery or create any sort of push towards abolishing racial injustice.
