She was also regularly depicted as an active participant in warfare; indeed, the battlefield was sometimes referred to as "the garden of the Badb". During the First Battle of Mag Tuired, Badb—along with her sisters, Macha and Morrígan—fights on the side of the Tuatha Dé Danann. Using their magic, the three sisters incite fear and confusion among the Fir Bolg army, conjuring "compact clouds of mist and a furious rain of fire" and allowing their enemies "neither rest nor stay for three days and nights". Badb plays a similar role in the Táin Bó Cúailnge, terrorising and disorienting the forces of Queen Medb and causing many to fall on their own weapons. She would often take the form of a screaming raven or crow, striking fear into those who heard her, and could also be heard as a voice among the corpses on a battlefield.
