The members of the Mormon Battalion have a surprise run-in with wild bulls at a crossing of the San Pedro River. A handful of battalion members are injured as the bulls charge the men, mules and wagons.
In his personal account of the battalion's actions, Col. Cooke records seeing a Cpl. Frost coolly stare down a charging bull and hold his ground: "He aimed his musket very deliberately and only fired when the beast was within 10 paces; and it fell headlong, almost at his feet."
