"Interior of the outbuilding attached to Marshal Kane's Police Headquarters, Holliday Street, Baltimore- discovery of cannon, muskets and ammunition intended for the service of the Secessionists. General Banks promptly arrested Marshal Kane as the most active Secessionist in Maryland, and incarcerated him in Fort McHenry. He supplied his place by Colonel Kenley, a tried and trustworthy officer. Provost Marshal Kenley actively pursued his search after concealed arms. He took possession of the late marshal's office, the entrance of which was guarded by a cannon planted in the hall and officers with drawn swords, a precautionary measure rendered necessary by the disturbed state of the city. The search after arms was eminently successful. In an old back building of the City Hall, used by Marshal Kane, were found two 6-pounder and two 4-pounder guns, half ton of assorted shot, four hundredweight of ball, eight hundred rifle-ball cartridges, gun carriages, etc. In the office and under the marshal's office, in the floors and in the ceiling, arms and ammunition were found, among them a case of splendid pistols, two hundred and fifty muskets and rifles, twenty-five of which were Minie, besides several muskets which were supposed to belong to the Massachusetts soldiers disarmed by the mob on April 19th." —Leslie, 1896
