In February 1804, Usman dan Fodio ﵀ left the city of Degel with his followers. Sultan Yunfa of Gobir had declared the jama’a his enemy and cut off its freedom of movement. The Shehu moved with his brother Abdullahi dan Fodio ﵀, his son Muhammad Bello ﵀, and hundreds of households to Gudu, a place on the western edge of Gobir.
For Usman dan Fodio ﵀ this journey was a Hijrah, a withdrawal of religious meaning, not merely a flight. At Gudu he was proclaimed Amir al-Mu’minin by the jama’a. From that moment the breach with Gobir was final.
Yunfa sent successive patrols to harass the jama’a. Cattle were stolen, supplies plundered, small groups taken captive. In the months between February and June the conviction grew that a great clash was unavoidable.
When Yunfa heard that the jama’a was moving eastward toward the lakes near Tabkin Kwotto, he assembled his cavalry. Warriors of allies among the Tuareg and the Sullubawa joined him. The Gobir army was numerous, mounted, and equipped for the open plain.
