"Agnes Darling, if such should be we never meet again, while firing my last shot, I will gently breathe the name of my wife - Agnes - and with wishes even for my enemies I will make the plunge and try to swim to the other shore"

The quote by Wild Bill Hickok reflects an extensive combination of love, bravery, and approval of fate. Expressed in a letter to his spouse Agnes, Hickok openly acknowledges the possibility of his imminent death, likely due to the unsafe nature of his life in the American frontier as a gunslinger, lawman, and folk hero.

Hickok begins with an affectionate address, "Agnes Darling", indicating a deep emotional bond and authentic inflammation towards his wife. His use of the word "beloved" highlights an intimacy and warmth that contrasts greatly with the harsh truth of his circumstance. He is acutely mindful that their reunion might never happen. This awareness is encapsulated in the phrase "if such must be we never reunite", laying bare his pessimistic outlook on surviving his perilous journey.

The images of "shooting my last shot" serves a double function. Literally, it describes the last act of defense in a deadly confrontation, a not unusual event in Hickok's turbulent life. Metaphorically, it signifies the nearing end of his life's struggle, with "the last shot" being his last attempt to hang on to life in a hostile world.

The line "I will carefully breathe the name of my better half - Agnes" is both poignant and poetic. In this ultimate minute, he looks for solace and strength in her name, conveying that she is his final thought and convenience. It reveals a tender vulnerability, illustrating how love transcends even the most trying situations.

His intent to face death "with dreams even for my opponents" stands out. It suggests a magnanimity and a desire to leave behind any grudges, embracing a tranquil departure. Lastly, "try to swim to the other shore" represents his hope for what lies beyond life-- a clean slate, or an afterlife. This metaphorical crossing to "the other shore" hints at an approval and preparedness to face whatever follows death.

Ultimately, Hickok's words portray a guy deeply in love, fixed up with his death, and confident for peace beyond the world he understood.
