Hubbard allegedly spent six weeks drilling this convict crew, turning them into a splendid fighting unit, “with some seventy depth charge runs to their credit and not a single casualty.” But according to naval records, he was relieved of command before the ship was even launched, by the commandant of the Boston Navy Yard, who declared him “not temperamentally fitted for independent command.” There is no record that Hubbard saw action in the Atlantic at any time.
