What did Mr. Dimmesdale tell the people of New England before he died?

Before he dies, Dimmesdale stands on the scaffold with Hester and Pearl in front of the townspeople. When he does this, he reveals that it was he who committed the sin of adultery with Hester and that he is the father of Pearl. Additionally, he opens up his shirt to reveal a red letter on his chest. Dimmesdale then dies.
