AUGUSTUS S. MULVANITY, LTJG, USN
Augustus Mulvanity '23
Date of birth: January 17, 1901
Date of death: June 10, 1930
From the 1923 Lucky Bag:
Augustus was lost on June 10, 1930 when the ship he was aboard, SS Fairfax, collided with the tanker SS Pinthis. Fairfax caught fire and caused the death of 27 people aboard, including Augustus, his wife, and his young daughter. Pinthis sank with the loss of all twenty crew.
From Find A Grave:
Nashua Telegraph Jun 16, 1930 front page and page 2
Impressive and solemn services with full military rites accorded an officer who died in the service of his country were given the remains of Lieutenant Augustus Shea Mulvanity, United States Navy, and 20 month old daughter Eileen, who with Mrs. Mulvanity were among the victims of the Fairfax disaster off Scituate, Tuesday night, yesterday afternoon. The body of the wife, Mrs. Lucille Buckley Mulvanity had not been recovered as yet from the sea at the scene of the disaster. Rev. Matthew Creamer, permanent rector of the church gave a short eulogy in which he praised the bravery of Lieutenant Mulvanity in his brave effort to save his wife and child and asked the congregation to rise and say three "Our Fathers" for the recovery of the body of Mrs. Mulvanity, to offer some little consolation to the grief stricken parents of the girl.
It's unclear if this should be considered an operational loss. If Augustus was en route to a new station or otherwise under official orders, it would be.
