|Department||Baltimore Police Department|
Battaglia was the only Italian-American police commissioner of Baltimore, controlling a police department previously dominated by Irish-American police officers during a time period nicknamed the "Holy Roman Empire." Battaglia would lose the post for a consultant position in 1984 to Bishop L. Robinson as Mayor Donald Schaefer shifted control of the department to the city's majority African American community. It was under Battaglia that former BPD officer Gary D'Addario was elevated to the rank of lieutenant. D'Addario is best known as the shift commander featured in David Simon's Homicide: A Year on the Killing Streets book and was the inspiration for the character of Al Giardello seen on NBC's Homicide: Life on the Street. During the Baltimore riot of 1968, Battaglia was ranked as a Lieutenant Colonel and was the Department's official Field Force Commander.

the mayor acknowledged the city's changing demographics by dragging Battaglia into a well paid consultant position and giving the black community a firm lock on the upper tiers of the police department.
