British dummies on Evacuation Day

First, top o' the Evacuation Day mornin' to ye! If you're a Boston City Hall worker or the parent of a BPS student, you're probably just now getting up, no? J.L. Bell posts an account from Gen. John Sullivan on pointing his spyglass at British fortifications in Charlestown on March 17, 1776:

Meanwhile, Paul Revere tweets:
