The Battle of Port Hudson was the final engagement in the Union campaign to recapture the Mississippi. While Union General Ulysses Grant was besieging Vicksburg upriver, General Nathaniel Banks was ordered to capture the Confederate stronghold of Port Hudson, in order to go to Grant's aid. When his assault failed, Banks settled into a 48-day siege, the longest in U.S. military history.
The Compromise of 1877 was an informal, unwritten deal that settled the intensely disputed 1876 U.S. presidential election. It resulted in the national government pulling the last federal troops out of the South, and formally ended the Reconstruction Era.
