By the early part of 1914 I had seen a good deal of experience in tracing bomb outrages to certain of the anarchistic and Black Hand elements in the population of the city. As the year wore on these occurrences became so numerous as to warrant special attention, and on August 1, the approximate date of the outbreak of war in Europe, Police Commissioner Arthur Woods created in the police department the Bomb Squad. I was in command, and reported direct to the Commissioner. As the volume of work increased, and more men were taken on, the Commissioner delegated his supervision of the Bomb Squad to Guy Scull, who was then Fifth Deputy Police Commissioner, and who is now a major in the United States Army. That supervision was later passed on to Nicholas Biddle, a Special Deputy Commissioner, who, as I write this, is lieutenant-colonel in the United States Army, in charge of the Military Intelligence Bureau in New York; and following Mr. Biddle, Fuller Potter, another special Deputy Commissioner, and now a major in the Military Intelligence, directed the policies of the Squad. Within a few months the personnel of the Bomb Squad included the following picked men: George D. Barnitz, Amedeo Polignani, Henry Barth, George P. Gilbert, Edward Caddell, Patrick J. Walsh, Jerome Murphy, James J. Coy, Valentine Corell, James Sterett, Henry Senff, Michael Santaniello, Joseph Fenelly, Joseph Kiley, Charles Wallace, William Randolph, Thomas Jenkins, and Anthony Terra--all detective sergeants, and George Busby, a lieutenant. To this list were added the names of James Murphy, Robert Morris, Thomas J. Ford, Walter Culhane, Vincent E. Hastings, Thomas J. Cavanagh, Louis B. Snowden, Thomas M. Goss, Daniel F. Collins, Frederick Mazer, Edward J. Maher, Walter Price, William McCahill, and Cornelius J. Sullivan. It made a list of fine material for the work which we were called upon to do, and no one will begrudge me here a word of tribute to their aptitude, their courage--to all of the qualities which made them such able and vigilant guardians of the neutrality of our country during the years preceding our entrance into the war. Many of the Bomb Squad went to war later: Barnitz became a junior lieutenant in the United States Navy, in intelligence work of a high order. Barth, Caddell, Corell, Fenelly, Jenkins, Walsh, Sterett, Santaniello, Randolph, James Murphy, Morris, Ford, Culhane, Hastings, Cavanagh, Snowden, Goss, Collins, Price, Mazer, Maher, McCahill and Sullivan became sergeants in the Corps of Intelligence Police of the National Army. And after I became connected with the Military Intelligence Branch of the War Department, I had frequent occasion to deal during the war in coöperation with the men whom I have mentioned in service.
