Yes, that’s the exaggerated tale that everyone knows.
In “Destruction and Its Impact on Ancient Societies at the End of the Bronze Age” <https://www.lockwoodpress.com/product-page/the-fall-of-the-b...> Jesse Millek examines 153 sites claimed to have been destroyed and found that 61% never happened, happened during a different time period, or had a different cause.
Even without buying the whole book you can download the appendix where he summarizes the results. A few notable entries:
Shiqmona: The possibly destroyed public building dates to the fourteenth century BCE. No end of the Late Branze Age destruction was uncovered.
Tell Irbid: C14 dates derived from short-lived samples places the destruction event between 1395–1260 BCE.
Krisa: There is only a statement that the site was destroyed with no published evidence of destruction in any structure.
Iria: Some burnt material in a pit was assumed to be a destruction. There was no damage visible to the buildings.
Athens: The Houses on the North slope were not houses at all. It was refuse that was dumped on the stairs.
Ayios Stephanos: Burning was uncovered in one room from Trench Beta 11. No other damage was recorded.
Amman Airport Structure: Evidence of burning in Room VII can be attributed to the hearth in that room.
Pefkakia: Adrimi-Sismani repeatedly cited a destruction, even though the excavators clearly stated the site was abandoned.
Tell el-‘Ajjul: Bell simply placed it on a map as destroyed with no citations. There was no settlement ca. 1200 BCE.
