General Thomas Swearing in the Volunteers Called into the Service of the United States at Washington, D.C.

Winslow Homer's wood engraving documents a Civil War recruitment ceremony, with General Thomas administering the oath to a gathered crowd before a classical government building. Published as a news illustration in Harper's Weekly, the work exemplifies the woodcut-based visual journalism that dominated American newspapers during the 1860s. Homer's precise architectural rendering and careful attention to individual figures reflect the documentary function of wartime illustration. Such images, distributed weekly to thousands of readers, established the narrative and visual conventions that would later define sequential art—framing historical moments through composed scenes that guided viewer attention and established editorial perspective.
