Far Isle was a human colony world. In 2492, a massive insurrectionist uprising occurred on the planet. The United Nations Space Command was unable to contain the rebellion, prompting the UNSC to declare code Bandersnatch: the UNSC used nuclear weapons to raze the colony.
The colony's total destruction is often cited by insurrectionists as the cause for their fighting. The destruction of Far Isle was arguably the cause of the Insurrection. However, the Insurrection is generally acknolowledged to have begun following the Callisto Incident in spring 2494.
The nuclear bombardment of Far Isle likely appears in the Halo Legends episode Origins when Cortana discusses the Insurrection. A flight of GA-TL1 Longswords is shown dropping bombs on a coastal city; in the next shot, a burning, slagged crater is shown in the middle of the city.
