Come to hear Middie Clapp Baker talk about her reminiscences of the events leading up to the fortification of Dorchester Heights and how that fateful night resulted in the British being forced to give up their occupation of Boston without a shot being fired. Through the magic of time travel, Submit Baker (born Submit Clapp) will share her memories about events and people and Dorchester life in the second half of the 18th century.
