In George Orwell's Animal Farm, Mr. Frederick was not mentioned after the Battle of the Windmill. Can we safely assume that his fate was similar to that of Adolf Hitler, his historical parallel?
Frederick is the shrewd owner of the neighboring Pinchfield farm, who is known for being "perpetually involved in lawsuits." He attempts to take advantage of Jones's misfortune. Frederick tricks the animals by purchasing timber from them and paying for it with counterfeit bank notes. Shortly after stealing the timber from the animals, Frederick and his troops attack Animal Farm and destroy the windmill before being driven out of the farm by the animals. In the novella, Frederick's character symbolically represents Adolf Hitler, the leader of Nazi Germany during the 1930s and 1940s. Similar to how Hitler decided to attack the Soviet Union during World War II, Frederick chooses to attack Animal Farm, which allegorically represents the Soviet Union throughout the novella. In the novella, Frederick's character is not mentioned after the Battle of the Windmill. Given that the story is the allegorical tale of the Russian Revolution and the early years of the Soviet Union, the plot and action of the story are focused on Animal Farm and Napoleon's reign, not on Frederick's fate. While Orwell chose not to elaborate on Frederick's fate, one cannot assume that Frederick committed suicide like Adolf Hitler. Essentially, there is no way of telling for sure whether Frederick committed suicide like his historical parallel.
