Answer:
Uriah Galusha Pennypacker
Explanation:
Uriah Galusha Pennypacker (June 1, 1841/1844 – October 1, 1916) was a Union general during the American Civil War. He may be the youngest person to hold the rank of brigadier general in the US Army; at the age of 20, he remains the only general too young to vote for the president who appointed him.
