Amsterdam, June 29th, 1781.
Sir,
I have the honor to inform your Excellency that I got to Amsterdam on Tuesday morning. It has been thought advisable to wait a few days, that we may sail with a Dutch squadron of fourteen sail, destined as a convoy to the Baltic. The loss of the ship Marquis de Lafayette, which is confirmed by Lloyd's list, renders every precaution necessary, and essential to prevent a further disappointment in supplies.
I hope your Excellency will approve of the reasons for delaying our departure, which must be amply compensated by the benefit of a convoy through the North Sea. I beg leave to request that Colonel Laurens's servant may be informed, should he apply to your Excellency, that, if he leaves Paris immediately and travels with despatch, he will reach this place in time to embark with us for America. Any commands, which your Excellency may please to honor me with, and which may be transmitted by him, will be faithfully attended to.
I beg you will present my best respects to your grandson.
I have the honor to be, with profound respect, &c.
W. JACKSON.
TO DAVID HARTLEY.
