He carried on much as he did before the war. Washington struggled to make a profit as a plantation owner. When not bemoaning the weather and the catastrophes it wrought on his crops, his letters reveal an abiding interest in seeds and soil.

Both he and Martha were chagrined when their retreat, Mount Vernon, became a tourist destination. Patriotic tourists imposed a financial burden on the Washingtons who entertained unsolicited citizens as guests.

Well, for half that time he was fighting the war / managing his army, the Treaty of Paris didn't occur until 1783.

His time spent between 1776 and 1782 is fairly easy to track by way of the battles he was involved in, mostly taking place in the Pennsylvania/New Jersey/New York area until 1781. He took his troops down to Virginia at that point. Once the Battle of Yorktown took place in late 1781, it signaled an end to the war. Only once the treaty was signed and he resigned his commission in 1783 was he was able to return home to Mount Vernon. Interestingly enough he had only been home for a total of five days during the entire 7 years of the war. Upon returning home he dumped all of his campaign equipment in the dining room (including two very large marquee tents), much to his wife's chagrin, and tried to return to focusing on running his plantation as he did prior to the war. This even included a trip out to western Pennsylvania to take a look at land he had been given due to his involvement in the French & Indian War. He was still involved in politics, however, chairing the Constitutional Convention in 1787. Fortunately for us, Washington understood the importance of what he was doing and kept copies of all of his correspondence throughout the war, and still much survives after, so we have a very good record of his life.
