I think that the harsh winter was a big part of the war because the Americans lost a lot of soldiers and I think that the British had the upper hand. Because there was a lot of letter about how much they wanted to go home. Like George Washington wrote a letter saying that they were going to die if the weather  was so bad. And there was a doctor that said that it was very bad and that people had the flu and other bad stuff . And that is why  this was a very big factor in the battles and the stuff that happened in the American Revolution.
