Answer (A)-They helped the war effort in many different ways.
Explanation:
I would not say, "late summer", because <u>Siege of Yorktown</u> initial movements started on September 28th and British troops surrender led by <u>Lieutenant General Charles Cornwallis</u> happened on October 19, 1781, at Yorktown, Virginia. Franco-American commanders were <u>General George Washington</u> and <u>Jean-Baptiste Donatien de Vimeur, Comte de Rochambeau</u>. <u>Siege of Yorktown</u> was the last major land battle of the<em><u> American Revolutionary War</u></em>, as the surrender by <u>Cornwallis</u>, and the capture of his army, prompted the British government to negotiate an end to the conflict. After the British surrender, <u>Washington</u> sent Tench Tilghman to report the victory to Congress. The Treaty of Paris was signed on September 3, 1783, formally ending the war.
