[Extract]

We understand here that Batteries, may be constructed at the entrance of the Bay of Boston so as to prevent the egress & regress of any Ships whatever. If this be fact, would it not Sir be a signal stroke to secure the Fleet & Army in and before Boston so as to compel a surrender at discretion. While I write this, I assure you my heart is elated with the contemplation of so great an event. A decisive thing, that would at once end the War, and vindicate the injured liberties of America. But your judgement, and that of your brave Associates, will best determine the practicability of this business.
