Tomorrow, at twelve o'clock in the forenoon, the experiment will be tried upon the Alarm Guns, which are placed upon the Delaware, betwixt this city and the capes, of which the Committee of Safety thinks proper to inform the public, to prevent any confusion. We hear that on Monday last [April l], the sloop Endeavor, Job Trip master, being on her passage from Dartmouth to this place, to the northward of Egg Harbour, was chaced and come up with by a tender carrying four carriage guns, ten swivels, and thirty-five men, fitting out by the Phoenix, and commanded by one Butler, a midshipman. The tender was not content with firing a broadside at Capt. Trip's vessel, after she had hauled down her sails, but went along side, after using much scurrilous language, ordered another broadside t.o be fired, by which Captain Trip received a ball in the thigh, which broke and much shattered it; the mate also had a ball went through one thigh, and lodged in the other. An officer afterwards came on board, and told Capt. Trip, that Butler (the Captain of the tender) out of his clemency, had consented to give him his boat, on condition he would make the best of his way on shore, which Capt. Trip represented as impossible, for himself and his mate both being wounded, they could neither stand nor sit. They then gave them the three hands belonging to the sloop, who, after much difficulty, reached the shore. The Captain and Mate were both dangerously ill, having been thirty-six hours without any dressing to their wounds. The tenders's people, after plundering the sloop, scuttled, and set her on fire.
