Military Intelligence Division, of the General Staff, sent a great many character and loyalty investigations of overseas cases, officers’ investigation cases and a large variety of cases of special investigation of both positive and negative nature, to A. P. L. in New York. A separate department was established in New York headquarters exclusively to handle the cases coming to New York Military Intelligence in Washington. Within the seven months ending December 11, 1918, the New York office received 5,046 cases of the types above mentioned. Perhaps a man going overseas would give from one to ten references, say an average of four references to each case, which would mean the interviewing of more than 20,000 individuals at the request of the War Department in Washington. The men who did this work did not get a cent for it. The territory covered by the Division extends from Poughkeepsie, New York, to Montauk Point, Long Island, a distance of about 200 miles. The cases would be scattered all over this territory, and very often the same case would require two or more investigators. Beside all of these rather heavy duties in connection with the big government work, A. P. L. had daily requests from the Intelligence Office at Governor’s Island, the Port of Embarkation at Hoboken, and the various other Intelligence Offices in and around New York City. Every possible assistance was rendered these various officers. It was impossible to classify all of this work in the files, so that the entire number is not available. As the perfectly interlocking system of intelligence of the A. P. L. in the great city became known, the agents of the Department of Justice and the officers of the various Military Intelligence services got in the habit of calling on headquarters at A. P. L. for all sorts of information. Quite often they would call regarding some case which needed looking into at a town a long distance away. The name of an A. P. L. division at that point would be given, and the case turned over to the latter by telegraph. Thus it is easy to see that the web of New York, expanded into the web of A. P. L. all over America, was of almost incalculable benefit to all of the U. S. Departments concerned in any way with the war.
