The Battle of Apple River Fort, occurred on the late afternoon of June 24, 1832 at the Apple River Fort, near present-day Elizabeth, Illinois, when Black Hawk and 200 of his "British Band" of Sauk and Fox were surprised by a group of four messengers en route from Galena, Illinois. One of the couriers was wounded in the thigh as the riders quickly made for the protection of the nearby stockade. Courier Fred Dixon lagged behind and provided cover for his comrades. The other couriers rode ahead to warn some 70 settlers of the approaching Sauk and Fox, thus saving their lives. The small company of militia at the fort, about 28-30 men and boys led by Captain Clack Stone, fought off Black Hawk's 150-man war party in an action that lasted about an hour. The withering pace of the gunfire eventually convinced Black Hawk that the fort was too heavily defended to lead a direct attack. He considered burning the fort, then switched to raiding cabins of foodstuffs, clothing and cooking utensils. In the gathering darkness, Black Hawk and his war party retreated.

The British Band was a mixed-nation group of Native Americans commanded by the Sauk leader Black Hawk, which fought against Illinois and Michigan Territory militias during the 1832 Black Hawk War. The band was composed of about 1,500 men, women, and children from the Sauk, Meskwaki, Fox, Kickapoo, Potawatomi, Ho-Chunk, and Ottawa nations; about 500 of that number were warriors. Black Hawk had an alliance with the British that dated from the War of 1812, giving them their colloquial name. The band crossed the Mississippi River from Iowa into Illinois in an attempt to reclaim their homeland and in violation of several treaties. Subsequently, both the Illinois and Michigan Territory militia were called up and the Black Hawk War ensued.
