Answer:
George Washington
Explanation:
George Washington was the top army general during the American Revolutionary War. He was a very effective military commander who had proven his worth in the French and Indian Wars, a couple of decades earlier.
George Washington was able to keep his army controlled and well prepared, even in the hardest moments. With time, his strategy proved succesful and he was able to limit British control to New York City, from where the British army would finally depart in 1783.
The answer should be B! It's actually kinda funny. Northerners thought that the Confederate army would be easily defeated and that the Civil War was going to begin and end at the Battle of Bull Run. So, lots of spectators watched, but they were quickly proven wrong, as the war lasted for years.
