Nope. Read your actual history and not the handful of propaganda paragraphs said in school. We had almost little to nothing to do with it. We lost almost all of our setpiece battles. Our real, nonpropaganda victories only came about when the French sent masses of trained troops to the north and midAtlantic while Spain sent a fair amount to the deep south. I'll go pull up some stats and come back. But the fact that US militias once us our freedom is BS. France and Spain had far more to do with it.
So, here ya go. Back with a few actual facts rather than my memory. While most people are at least vaguely aware that France had "a few" troops in the US thanks to Patriot (which gives way too much credence to the Americans at Yorktown it was basically all French), they are unaware that Spain had a large number of troops in the South and that one of the biggest battles in the Revolutionary War was in.....Pensacola Florida. Count Bernardo de Galvez led Spanish troops to take Baton Rouge, Natchez and Mobile and then settled down for a seige at Pensacola. 7,000 Spanish troops encircled about 4,000 British troops and after the fighting the Spanish basically lost 85 soldiers in exchange for killing over 200 and capturing about 1,500 British. That may not sound like a lot when you read about Civil War and WW2 battles, but the Battle of Bunker Hill was about 2,000 Americans versus 3,000 British and the British only had about 270 KIAs.
Meanwhile at Yorktown the "American" victory that was the pivotal battle of the Revolutionary War, although the combined allied forces were about 17,000, jus shy of 9,000 of that was French frontline troops while only about 3,000 American regulars were there (another 5,000 or so militia that were used primarily only to dig treches and only shot some ceremonial bullets).
The other famous American only victories were all small. When Washington famously sailed across the Delaware to attack drunken German mercenaries celebrating Christmas, he had about 2,500 troops and they captured about 900. Cowpens had 2000 Americans vs 1,150 British; Ticonderoga had about 250 Americans versus 80 British; Princeton was about 4,500 Americans versus 1,200 British; Vincennes was 200 Americans versus about 100 British; Springfield was about 1,500 Americans versus 5,000 British; Lexington had 80 Americans versus 400 British and Concord had 4,000 Americans versus about 1,500 British. The rest were all losses excluding some even more minor raids.
All of the other major battles were British victories (like in the biggest battle of the war at Long Island).
Only Saratoga was an American only (with French advisors) victory that was bigger than the battle of Pensacola as there about 15,000 Americans versus 6,600 British.
So the biggest "American" victory in the Revolutionary War was mainly French. The second biggest WAS actually American. And the third biggest was Spanish with little to no American involvement. There wasn't even a close fourth in terms of battle size that "America" didn't lose.
