Extract of a Letter from the delegates of this State, at Yorktown, to his Excellency the Governor, dated Jan. 9. “A few days ago a large Brig was blown ashore five miles below Wilmington, and taken by General Smallwood. It proved a valuable prize, there being 7500 stand of arms, 1500 suits of clothes, baggage for the officers of four regiments, and a quantity of wine and spirits on board. Three other vessels are said to be drove ashore on the Jersey side, the inhabitants are taking proper care of their Cargoes.”
