The Battle of Yorktown was Mainly a French Victory
OK, Americans helped a little bit.
History is often the egoism of nations rather than the accurate accounting and highlighting of facts. This is especially true where events are located perilously close to a nation's cherished foundation myths. A case in point is the American War of Independence and its climatic battle, the Siege of Yorktown -- an event central to the "foundation myth" of the United States of America.
Usually presented as an "American" victory (with little or no French help), a closer analysis suggests that the battle was overwhelmingly a French victory and merely part of France’s much wider global war with the British Empire.
