Major André returned victorious from the Siege of Charleston on 18 June, and both he and General Clinton were immediately caught up in this news. Clinton was concerned that Washington's army and the French fleet would join in Rhode Island, and he again fixed on West Point as a strategic point to capture. André had spies and informers keeping track of Arnold to verify his movements. Excited by the prospects, Clinton informed his superiors of his intelligence coup, but failed to respond to Arnold's 7 July letter.
