The War of 1812 is mostly forgotten today, but it was a big deal in Jamaica Plain at the time. I've never seen any mention of Jamaica Plain men serving in the military during this conflict - perhaps there's something in the Town of Roxbury archives.
Salem Gazette February 28, 1815
At JAMAICA PLAIN,
On Tuesday morning at little past 7 o'clock the news of Peace was announced at Jamaica plain by the ringing of the bell, which continued at intervals during the whole day. In the evening the seats of fourteen gentlemen were elegantly illuminated, as were those also of three others on the following evening. The display was brilliant and animating.
