The privateer Genl Mifflin arrived here the 10th Inst. from a Cruise in which she has taken three Prizes, The Elephant a Kings Store ship, the Brig Betsey a merchant man in Ballast, and the Tartar an english Privateer of 26 Guns & 160 men. The Mifflin mounts but 20 Guns (6 pounders) finding therefor her Enemy Superior, the Commander Capt Babcock made a Desperate attack to board, in which the English Captain was killed and the ship directly surrendered.— Captain Babcock having now about two hundred Prisoners and his Provisions being short he was under the necessity of sending one hundred & ninety of them in the Brig which he gave for the Purpose, and they have since arrived in England as appears by the english Prints.— In order to secure an Exchange of an equal Number of americans Capt Babcock took a Receipt for these Prisoners from the master of the Elephant the master of the Brig & the 1st Lieutenant of the Tartar (the Captain of the latter being killed) promising a Release of american Prisoners accordingly.— I have had this Instrument authenticated by the admiralty of the Place and inclose the Copy in due form to serve as you may think necessary.—

Capt Babcock was obliged to quit the Tartar at Sea the 23d of June and if she is not taken we expect her hourly to arrive.— I shall deliver the prisoners who remain on board the Mifflin into the prisons here and shall desire Mr. Schweighauser to engage for their maintenance or I shall do it myself untill I receive your Orders: The mifflin and her Prizes if they arrive are to my address.

I am with the greatest Respect Dear & hond Sir Your dutifull & affectionate Kinsman
