If I were in Valley Forge at the time of 1777 and 1778 during the winter I would have not stayed. There are a lot of reasons why I would have not stayed. Some being because the lack of food, for example meat. The camp at Valley Forge was also small, it only had a few houses and huts and a mill for forging iron. That was not a lot to live with while having soldiers.
You had to share and sleep in huts with twelve men. I would guess that that would be very cramped and sometimes aggravating. There were no beds in the huts just a straw bed on the cold mud floor. You would have to live in these huts for six whole months with only one fireplace. I would not leave behind my family for this cold, starving, cramped winter.
