Marching north, the British Army brushed aside American light forces in a few skirmishes . Washington offered battle with his army posted behind Brandywine Creek . While part of his army demonstrated in front of Chadds Ford, Howe took the bulk of his troops on a long march that crossed the Brandywine beyond Washington's right flank .

The British captured the city on September 26, beginning an occupation that would last until June 1778 . </P>
