"The 11th of Sepr. last I was preparing Dispatches for you when the report of cannon at Brandywine interrupted my proceeding. The event of that day you have doubtless been informed of, which, excepting the Enemy keeping the ground, may be deemed a drawn battle. Genl. Washington collected his Army at Chester, and the Enemy's not moving towards him next day must be attributed to the disability they sustained and the burthen of their wounded. On the 16th of the same month, the two Armies were drawn up in order of battle near the White horse on the Lancaster road, when a most violent and incessant storm of rain prevented an action. Our Army sustained a heavy loss in their Ammunition, the Cartouch Boxes, especially as they were not of the most seasoned leather, being no proof agst. the almost incredible fury of the weather, which obliged Genl. Washn. to draw his Army up into the country till those injuries could be repaired, and a new supply of ammunition procured. The Enemy in the mean time kept on the West Side of Schuylkill. On Fryday the 19th about one in the morning the first alarm of their crossing was given, and the confusion, as you may suppose, was very great. It was a beautiful still moonlight morning and the streets as full of men women and children as on a market day. On the eveng. before I was fully persuaded that unless something was done the City would be lost; and under that anxiety I went to Col. Bayard, speaker of the house of Assembly, and represented, as I very particularly knew it, the situation we were in, and the probability of saving the City if proper efforts were made for that purpose. I reasoned thus--Genl. Washn. was about 30 Miles up the Schuylkill with an Army properly collected waiting for Ammunition, besides which, a reinforcement of 1500 men were marching from the North River to join him; and if only an appearance of defence be made in the City by throwing up works at the heads of streets, it will make the Enemy very suspicious how they throw themselves between the City and Genl. Washington, and between two Rivers, which must have been the case; for notwithstanding the knowledge which military gentlemen are supposed to have, I observe they move exceedingly cautiously on new ground, are exceedingly suspicious of Villages and Towns, and more perplexed at seemingly little things which they cannot clearly understand than at great ones which they are fully acquainted with. And I think it very probable that Genl. Howe would have mistaken our necessity for a deep laid scheme and not have ventured himself in the middle of it But admitting that he had, he must either have brought his whole Army down, or a part of it. If the whole. Gen. W. would have followed him, perhaps the same day, in two or three days at most, and our assistance in the City would have been material. If only a part of it, we should have been a match for them, and Gen. W. superior to those which remained above. The chief thing was, whether the cityzens
