The morning I intend to make the attack on the Fortifications on Sulivan's Island, which will be on the first of the Flood, I will hoist a Blue Flag at the Main Top Gallant Mast Head, which is to be signified to General Clinton from the Friendship, by an Union Flag at the Foretop Gallant Mast Head ー And should it suit the General that I should go upon the Attack, the Friendship shall loose her Main Top Gallant Sail; But should he wish to have it deferred 'till the morning following, then the Friendship shall hoist her Ensign at the Main Top Gallant mast Head ー In either case Guns are to be fired 'till I answer by hoisting the Standard at the Main Top Gallant mast Head. ー
