Writing to General Lincoln two months after the battle, Washington expressed his pleasure at seeing the bond between the French and Patriot armies undimmed by the failure at Savannah. With time, the Continental commander believed that the allies would become skillful at carrying out joint and combined operations, a faith aptly rewarded two years later when a Franco-American force beseiged and then captured a British army at Yorktown, Virginia.
"While I regret the Misfortune, I feel a very sensible Pleasure in contemplating the gallant Behaviour of the Officers and Men of the French and American Army; and it adds not a little to my Consolation to learn that, instead of mutual Reproaches, which too often follow the Failure of Enterprises depending upon the Coöperation of Troops of different Nations, their Confidence in and Esteem for each other are increased."
