Studying history is interesting. Every generation of historians seems to find some new way to look at events.
Yes, I'm currently reading "The Perils of Peace" by Thomas Fleming which starts with the surrender at Yorktown then travels back and forth in time around that event. As you point out, it was very much a global battle involving England, France, Spain and then Holland was getting into the mix as well.
Interestingly, July 4, 1776 is generally presented to us as a "done deal" but the British were still in possession of New York, South Carolina and Georgia then and still yet in 1782.
The concept of the "united" states was pretty loose and fluid, as they generally looked out for themselves and when asked by the Continental Congress to submit payment on April 1, 1782 to support the continued war effort, not one single dollar was deposited.
General Washington had a hell of a struggle. Another great book on this era is "1776" by David McCullough.
John Adams, the future 2nd President had written at the time that he saw the people divided by thirds. One third supported the Revolution, one third were Loyalists and one third were indifferent and just wanted to be left alone to settle in a new world.
Me?... I'm just glad to have been born in the USA. With all that's going on in the world now, there's at least one time each day while watching the news that my Wife and I look at each other and say "How did we get so lucky?"
Happy Fourth everyone.
