The Brandywine Valley, near the battle-ground, then, as now, teemed with agricultural wealth. The fine farms of the thrifty English settlers, many of whom traced their ownership back in a family line of three-quarters of a century, spread out along the creek in fine meadows of natural "green grass," and rolled upward over the hill-slopes, which, though broken and irregular, nowhere rise precipitously or to great height. The invading forces, as they marched up from the Chesapeake, could not but see the richness of the region, and one of their officers, conversed with by Joseph Townsend, exclaimed "in some rapture," Joseph says, "You have got a hell of a fine country here; which we have found to be the case ever since we landed at the Head of Elk." Along the hill-slopes, on the east side of the Brandywine, from Chad's Ford up to Brinton's, a distance of about three miles, the Americans lay on the night of September 10th. Wayne was posted to guard the lower ford, and Sullivan had his own division and those of Stirling and Stephen stretched up along the stream. Greene's division formed the reserve. Sullivan's duties included the guarding of the fords above Brinton's, and he had become possessed of the unfortunate idea that there were but three of these fordable, and that beyond the three in question there was no place for a distance of twelve miles where the hostile army could cross. He therefore sent detachments on this evening of the 10th to the three fords--the Delaware regiment to Jones's, and battalions of Hazen's regiment to Wistar's and Buffington's. With this he rested content. It is, however, true that the cavalry at his command seems to have been pitifully meagre: he asserts that on the morning of the battle he had _four_ light-horsemen only, two of whom he sent on scouting duty, retaining the other two to serve as couriers to head-quarters. Below the line of Washington's main army, at Pyle's Ford, were posted the Pennsylvania militia under General Armstrong, and below their position the Brandywine enters rocky hills, flowing between steep banks that forbid the easy passage of an army.
