Didn't think George took charge in the field until 1776 outside of Boston.
From the Real Story of the American Revolution Web site: http://www.rsar.org/military/battles.htm
1775 June 17: Breed's Hill (Boston MA) -- While this is often called the battle of Bunker Hill. there was no fighting on Bunker Hill -- this hill is adjacent to (behind) Breed's Hill. Two British attacks against entrenched rebel militia positions on Breed's Hill were beaten back by concentrated musket fire. The third British attack succeeded only because the American militia ran out of ammunition. The militiamen were driven out of the fortifications closest to Boston, but they sustained only half as many casualties as the British, they remained in a dominating position, and Boston now came under siege. Also on this day George Washington was named Commander-in-Chief by the Continental Congress, and on July 2 he arrived in the Boston area to relieve Gen. Artemas Ward, who had been serving as Commander-in-Chief and directing the efforts of militia regiments from many nearby states.
(Casualties: U.S. militia 450, British 1,050)
so it would appear the troops were authorized on the 14th and George was selected shortly thereafter on the 17th. (emphasis added and typo corrected)
“Since 1775, when General George Washington first lead soldiers into battle”
Didn’t think George took charge in the field until 1776 outside of Boston.

You can hit abuse on yourself and ask moderators to remove your post if you are embarrassed by your blunder.
I wonder why you would think that the Army does not know how many years they have been in existence?
