On the night of the 20th, still without having joined forces with the other three groups, MacCarthy's force camped by a tributary of the Pra River. The next day, at around 2pm, they encountered a large enemy force of around ten thousand men; believing that the Ashanti army contained several disaffected groups whose chiefs were willing to defect, MacCarthy instructed the band to play God Save the King loudly. The Ashanti responded by approaching closer, beating war drums, and his beliefs were swiftly dispelled.
