“TO JOHN ASHMEAD, Esq.: 

"CONTINENTAL NAVY BOARD, 

BORDENTOWN [N.J.], April 8th, 1778.

"Sir: Whereas, it is probable that the Enemy may make an Excursion in order to destroy, or take possession of, the Shipping at this place, you are therefore hereby directed to prepare for sinking the Mercury Packet under your command;¹ you are to find immediately some suitable Place for the Purpose, and remove here there, and, when she is emptied, have two Holes bored through her Bottom, and Plugs inserted, so that in case of alarm, the Plugs being drawn, she may sink forthwith. It will be convenient to have the Plugs very long, and secret Marcks made by which they may be easily directed to the Holes in case we should have an opportunity of raising her again. Trusting to your Diligence and Discretion in conducting this Business, 

“We are your friends, 

"FRAS. HOPKINSON."
