This was a pretty weird poem because the protagonist doesn’t seem to have any emotion even though he seems to be dying as he disappears under the ice. By using the words “imperturbable”, “coolly”, and “sad”, the author portrays a depressed man disappearing forever into the water and never being seen again.
The Farewell
They say the ice will hold so there I go, forced to believe them by my act of trusting people, stepping out on it, and naturally it gaps open and I, forced to carry on coolly by my act of being imperturbable, slide erectly into the water wearing my captain's helmet, waving to the shore with a sad smile, "Goodbye my darlings, goodbye dear one," as the ice meets again over my head with a click.—Edward Field
