For the inauguration of Unionist Louisiana Gov. Michael Hahn on March 4, 1865, Patrick Gilmore gathered all military musicians in New Orleans for the swearing-in ceremony at Lafayette Square. The band leader also brought in other local musicians and bands. When he had all his players assembled, there would have been several hundred performers. This drawing by C. E. H.
