A detailed regimental history recounts the mobilization, coastal defense challenges, training, garrison service at several forts, routine life, and administrative records of a Massachusetts heavy artillery regiment during the Spanish-American War. Chapters trace marching orders, station assignments, personnel organization, and the regiment's discipline and esprit de corps through periods of suspense, rumor, and final demobilization. The book includes rosters, muster-rolls, a chronology of operations, and illustrations, and emphasizes the steadfast performance of men on coast-defense duty who maintained readiness despite limited action and public indifference.
