On June 15, 1808, the French army stormed the Portillo, an ancient gateway into the city defended by a hodgepodge battery of old cannons and a heavily outnumbered volunteer unit. Agustina, arriving on the ramparts with a basket of apples to feed the gunners, watched the nearby defenders fall to French bayonets. The Spanish troops broke ranks, having suffered heavy casualties, and abandoned their posts. With the French troops a few yards away, Agustina herself ran forward, loaded a cannon, and lit the fuse, shredding a wave of attackers at point-blank range.
