On this day 250 years ago the Massachusetts House of Representatives named one of its members, 68-year old Seth Pomeroy, as “general officer” for militias. Pomeroy would subsequently fight as a volunteer without command at Bunker Hill, serve as the Major General in command of the Massachusetts Militia and serve in the Continental Army as a Brigadier General. He would die of disease in Continental Service in 1777 at the age of 70.
