This Day in History: September 17

The Enemy and we are very near Neighbours. Our advanced Works are not more than five or 600 Yards from theirs, and the main body of the two Armies scarce a Mile. We see every thing that passes, and that is all we can do, as they keep close on the two Peninsulas of Boston and Charlestown, both of which are surrounded with Ships of War, Floating Batteries, &c. and the narrow necks of Land leading into them fortified in such a manner as not to be forced without a very considerable Slaughter, if practicable at all.
