In the summer of 1809, as Napoleon’s armies swept through Spain, a group of Aragonese partisans set up a clandestine bullet factory in the rugged Sierra de Tardienta. This act of resistance, almost mythic in its daring, was captured by Francisco de Goya in his 1810 work Manufacture of bullets in the Sierra de Tardienta. Goya, then serving as official painter to the Spanish court and a witness to the devastation of the Peninsular War, was among the first to document such scenes of civilian defiance.

The painting is part of his celebrated series on the war, which he described as “the disasters,” offering a rare, unvarnished look at the mechanics of rebellion. At the heart of the picture, a handful of men and women labor by torchlight, melting lead and casting bullets, their faces tense with urgency. The cramped, makeshift forge is rendered with grim clarity: crucibles, tongs, and scraps of metal litter the ground, while the flicker of fire throws harsh shadows on the cave walls. Goya’s eye lingers on the physical toll—soot-streaked faces, raw hands, a child watching from the shadows—inviting the viewer to feel the weight of necessity and fear.

Unlike the heroic, orderly depictions of war by artists such as Jacques-Louis David, Goya’s scene is intimate and fraught, focusing on the anonymous labor that underpins resistance. The darkness presses in, but the glow of the forge becomes a fragile beacon of hope. The exact medium of Manufacture of bullets in the Sierra de Tardienta remains uncertain, though it belongs to the group of war images Goya produced between 1810 and 1815, many of which were preparatory works for his later prints. These pieces were not commissioned by the crown, but rather created out of Goya’s own compulsion to bear witness.

Some entered private collections before being acquired by public museums; this work’s early provenance is not fully documented, but it now forms part of the Prado’s holdings. In the context of Goya’s career, it marks a turning point from courtly portraiture to raw reportage, laying the groundwork for his later, darker visions of humanity.
