Sir/
In consequence of an Application from this Board, The Honorable the Marine Committee of Congress have Order'd down the Brigantine Andrew Doria Capt Isaiah Robinson whose Assistance we thought might be necessary in the Service you are directed to.
By the Rules Established by the Honorable the Continental Congress, the Officers of the United States Command all Officers of the like rank belonging to any particular State when employ'd together.
Of course Cap. Robinson will take the Command as soon as he joins you; You are therefore to follow his instructions on every occasion, (except they shou'd be contrary to those we have already given you) and as the good of the Service requires perfect Unanimity in the Officers, we recommend it to you, to Cultivate a good Correspondance with each Other.
[Endorsed] A Copy of the Above were sent to each Captain.
