Answer:
How does Black Hawk use rhetoric in this line to advance his purpose?
His heart is dead, and no longer beats quick in his bosom. He uses hyperbole, exaggerating his feelings of defeat by describing the experience as death, indicating to the audience that the two feelings carry similar weight.
He uses ethos, suggesting his behavior was an ethical and just reaction against the deceitful and immoral behavior of the white men.
He presents an antithetical statement, making a connection between two opposite ideas to use contrast as a means for justification.
He appeals to emotions and sentiment to distract his audience from the need for justification in favor of angering them...
Thus what I know for now
