Answer:
They were both civil war generals and wanted to preserve the Union
Explanation:
Grant and Lee both:
fought in the Mexican War
had tremendous passion for what they were fighting for
were stubborn and faithful.
Each was a risk taker.
rose to greatness in ability to turn to peace at the war's end.
behaved with enormous graciousness when they met briefly in Appomattox to finalize the South's surrender that led to peace.
