This early Disney film dwells more on the brawling and warring between Irish and British and Irish and Irish than on history. Still, if you listen closely, you will glean a tiny piece of historical information. It seams that in 1587, a treaty was proposed that would allow the British to stage a defence against Spanish invaders on Irish soil. How this treaty turned out is not covered. We do get the details of young Red Hugh's love life and how it figures into the joining forces of the O'Connells, the Sweeneys and the O'Neals to stand against British tyranny.
