[ WP ] You have a school project based on The Civil War , using a clock you go back in time and upon arrival your clock died ( ran out of battery life )

It was a mistake. 
 
 Not the war, my time travel. 
 
 I could use my knowledge of mechanics to advance the war machine to end this bloodshed quicker but then the horrors of World War 1 would happen before mankind's ability to understand that people are the nation and not the subjects to be ruled over. 
 
 I could use my knowledge of basic first aid and save thousands of lives. This is a better evil, but what could this do to the future that I know? If I am to exist into a living future then in history's past this might be the best course that I could venture to help the cause of humanity. 
 
 And here I am, at the [ Battle of Cowpens, ] ( https: //www.nps.gov/cowp/learn/historyculture/the-battle-of-cowpens.htm ) and I am mortified within myself of what any choice I make might change the future. 
 
 So I got on a horse with no name and I danced with the wolves.
