Quick answer

On 5 September 1781 a French fleet under the Comte de Grasse fought a British fleet under Rear Admiral Thomas Graves off the capes of Chesapeake Bay, and the French kept the bay that Cornwallis at Yorktown depended on. On 5 September 1914 the French Sixth Army began the move against the German flank that opened the First Battle of the Marne. Each has its own full story below.
