After a skirmish at Cooch's Bridge south of Newark, the British troops moved north and Washington abandoned a defensive encampment along the Red Clay Creek near Newport, Delaware, to deploy against the British at Chadds Ford. This site was important as it was the most direct passage across the Brandywine River on the road from Baltimore to Philadelphia. On September 9, Washington positioned detachments to guard other fords above and below Chadds Ford, hoping to force the battle there. Washington employed General John Armstrong, commanding about 1,000 Pennsylvania militia, to cover Pyle's Ford, 5.8 miles south of Chadds Ford, which was covered by Major Generals Anthony Wayne's and Nathanael Greene's divisions. Major General John Sullivan's division extended northward along the Brandywine's east banks, covering the high ground north of Chadds Ford along with Major General Adam Stephen's division and Major General Lord Stirling's divisions. Further upstream was a brigade under Colonel Moses Hazen covering Buffington's Ford and Wistar's Ford. Washington was confident that the area was secure.
