Those who lost it all and came back fighting: Ulysses S. Grant
Grant was the 18th president of the United States. He saved the Union during the Civil War. Yet, he led a life full of highs and lows. A West Point graduate, he left the Army after being accused of drinking on duty. Then he struggled for seven years, barely able to support his family.
When war broke out, Grant went back into the army, first as a volunteer, then as a colonel, and eventually as the top U.S. general. Wait, there's more--Grant was elected president, but he later burned through his money. He was flat-out broke, and ultimately had to write his memoirs on his deathbed in order to provide for his family.
At Shiloh in April, Grant fought one of the bloodiest battles in the West and came out less well. President Lincoln fended off demands for his removal by saying, “I can’t spare this man–he fights.”
For his next major objective, Grant maneuvered and fought skillfully to win Vicksburg, the key city on the Mississippi, and thus cut the Confederacy in two. Then he broke the Confederate hold on Chattanooga.
Historical assessments of Grant's legacy have varied considerably over the years. Historians have hailed Grant's military genius, and his strategies are featured in military history textbooks. Grant's presidency has traditionally been criticized for multiple scandals and for his protection of his friends.
Recent scholarship has recognized his achievements, and regarded him as an embattled president who performed a difficult job during Reconstruction.
