No, Mary Warren never told the truth about what happened in the woods.
Explanation:

She and the other accused girls went on a mission of conjuring things and practicing witchcraft. They had ulterior motives for this Abigail Williams wished to accuse Elizabeth Proctor of witchcraft so that she could marry her husband.
