When did Sack of Dun Gallimhe happen?

The Sack of Dun Gallimhe is a fictional event from J.R.R. Tolkien's *The Silmarillion*. It occurred during the First Age of Middle-earth, specifically during the War of Wrath. This war, which lasted for 50 years, began in the year 587 of the First Age and ended in 587. The sacking of the city, specifically, happened during the last year of the war, as part of the final stages of the conflict.

There is no precise date given in the text for the Sack of Dun Gallimhe. However, the events are narrated chronologically within the context of the War of Wrath. It is important to remember that Tolkien does not provide a precise calendar or year count for the First Age, so it's difficult to pinpoint an exact date.
