Explanation:
The most famous combat operation of the Civil War with participation of African American was the assault on Fort Wagner, carried out on July 18, 1863 by the 54th Massachusetts Black Volunteer Regiment (commander Colonel Robert Shaw). It was the first regular military unit in US history to consist entirely of African Americans. The 54th Massachusetts regiment became widely known for its courage, and this event contributed to the formation of new African American regiments, which, according to President Lincoln, played an important role in the victory of the North.
The Treaty of Versailles officially ended World War I and forced Germany to accept blame for the war.
