I had to memorize all my Presidents from a very early age. Lets see....Garfield or Arthur....hmmm....yeah, Arthur.
Well off the top of my head, they weren't used to the terrain and couldn't carry forth supplies. Also, I recall they had to surrender various forts in the middle of the war, losing a substantial amount of supplies, weapons and food.
The Puritans are a sect of Christianity. If I recall, they came from the Protestants; a.k.a the pilgrims who wanted to break away from the terrible Church Of England.
If I'm doing your homework; you're welcome heheh.
