Victor tells Robert that he must carry on the mission to destroy the monster.
In the letter dated September 2, 17 — , Walton grieves at the fact that he has found a friend who seems on the verge of death and that his own mission to discover a northwest Arctic passage has failed. He writes to his sister to remember him fondly and to wish her family well.
In the letter dated September 5, 17 — , Walton writes that Victor is now dying, and Walton has a near mutiny aboard his ship.

In the letter dated September 7, Walton is in deep despair, now far short of his goal. He informs the crew that they will return to England if they are not destroyed.
