The commanding general of the Union Army during the American Civil War. In the American Civil War, the Federal Army led by Grant won the final victory. However, after four years of bloody civil war, the two sides spent 15 billion US dollars on military expenditure and more than 700,000 soldiers died, countless towns and plantations became ashes. It had been the consensus of all soldiers that peace should be returned to the people. After the war, Grant showed great goodwill because the soldiers of the Confederate Army were also "our compatriots". In a house of Appomattox, Grant was wearing an ordinary soldier's suit. At that time, he was not a winning general, but an old soldier who wanted to go home after war. The officers and soldiers of the South were given adequate food and houses to return home, and the deserted land in South needed them to take care of. The cruel civil war ended quietly. Grant won the respect of all, and his loving and compassionate heart was remembered by the American people.
