The irony of religion
The reader learns that after the kidnapping of Eunice alongside her other family members, the Kahnawake natives kept her and assimilate her into their culture. Sadly, some of Eunice's siblings were killed during the capture. After assimilation, Eunice was married by the natives and got converted to Roma Catholicism. The irony is that the natives believe in God, but they kill and detain people they consider enemies.
The irony of the Kahnawake natives
The Native Americans do not want outsiders, and when the war breaks out, they kill and imprison them. The idea that the outsiders are killed shows that they are not wanted. Ironically, when Williams' family is captured, the natives release the rest of the family besides those killed on the condition that Eunice is left behind. Ironically, they assimilate Eunice to the local culture. The reader wonders why a girl from the outsider community can be assimilated to marry the native husband.
The irony of oppression
The Unredeemed Captive is a true story showing the two sharp sides of oppression. The story details how the war destroyed the community. The Europeans entered into a conflict with h natives. Ironically, the Europeans seemed superior with all machinery behind them, and they thought they would destroy the Natives. Ironically, the Natives were tactical, and they oppressed the Europeans by kidnapping, killing, and imprisoning them. William's family is an example of a European family that was badly oppressed by the Native community.
The irony of Stephen
Stephen is Eunice’s brother who relentlessly looked for her reunion. When their father died without tracing and locating Eunice, Stephen continued with the mission. The satire is that Stephen remained optimistic that he will see his sister again even after more than twenty years of separation. At last, Stephen met his sister when she was eighty-five years old. The moral lesson of this irony is that we should never give up.
