In the summer of 1777, while Washington was encamped near Brandywine, a large party of foragers came into the neighborhood, and the General gave orders to a company of his troops, to go in pursuit of them early the next morning, and, if possible, cut off their retreat. As an engagement might ensue, he also gave orders that the women should leave the camp. Receiving intelligence of the latter order, and unwilling to be included in it, the wife of Colonel Clement Biddle, an intimate associate of Mrs. Washington in the camp, went to the General and told him that the officers, who had gone on the expedition, would be likely to return hungry, and she would consider it a favor to be allowed to remain and prepare some refreshment for them. Washington complied with her request, and her servant was immediately posted off in search of provision.

Receiving information that a band of "rebels" was in pursuit of them, the foragers took a quick step out of the neighborhood. The pursuers returned at a late dinner hour exceedingly fatigued and ripe for attacking the "good things" prepared by Mrs. Biddle. Notified of her generosity, the officers forthwith repaired to her quarters, each saying, on his entrance, "Madam, we hear that you feed the army to-day." It is said that at least a hundred officers enjoyed her hospitalities on that occasion.
