Tuesday, September 16th, 1777.
Battle near White Horse Tavern, north of Paoli.
About nine in the morning we were informed that the enemy were advancing towards us. The troops got under arms and the baggage was sent off. An advance party of the enemy attacked our pickets just posted, about 300 strong, who shamefully fled at the first fire. About this time it began to rain such a violent storm that the arms were unfit for use, and orders were given to march to the Yellow Springs, a distance of 5 miles to the northward, where the troops arrived about 10P.M.
To President of Congress. Washington.
