Final answer:
The two men convicted of treason during the Whiskey Rebellion were pardoned by President Washington, and later, related individuals involved in Fries's Rebellion were also pardoned by President Adams.
Step-by-step explanation:
The fate of the two men convicted of treason during the Whiskey Rebellion is that they were pardoned by President Washington. As the sending of a massive army to western Pennsylvania took place to quell the rebellion, the response to the insurrection was considerable. However, President Washington and later President Adams showed clemency. Specifically, President John Adams pardoned the men involved in what became known as Fries's Rebellion, which was related to the same series of events and sentiments as the Whiskey Rebellion.
