The first official U.S. flag flown during battle was on August 3, 1777, at Fort Schuyler (Fort Stanwix) during the Siege of Fort Stanwix. Massachusetts reinforcements brought news of the adoption by Congress of the official flag to Fort Schuyler. Soldiers cut up their shirts to make the white stripes; scarlet material to form the red was secured from red flannel petticoats of officers' wives, while material for the blue union was secured from Capt. Abraham Swartwout's blue cloth coat. A voucher is extant that Capt. Swartwout of Dutchess County was paid by Congress for his coat for the flag.
