Twain rightfully hated King Leopold with a purple passion (see "King Leopold's Soliloquy") for his role in the deaths of millions of Africans.
 In reading "King Leopold's Ghost : A Story of Greed, Terror, and Heroism in Colonial Africa" by Adam Hochschild, I see that Twain's friend Henry Morton Stanley assisted Leopold in his plundering of the Congo and ruthless exploitation of its people. 
Was Twain ever aware of this? If not, why not? If he was, is there any record of his ever denouncing his old friend?
