This work identifies every person from Massachusetts and Maine who served in that conflict. The body of the book is arranged by state and thereunder by militia company. For each company, there is given the name of the company captain, the names and ranks of all the militiamen who served under him, and the company’s dates of service, place of organization, and duty station.
